In Japan, where the concept originated, KAIZEN applies to all aspects of life, not just the workplace. In America the term is usually applied to work processes.\r\n\r\nSee Also:\u00a0Kaizen Continuous Improvement -Definition, Kaizen Process\r\n\r\nKaizen\r\nKaizen Tools\r\n1. 5S\r\n\r\n5S is a philosophy and checklist for good housekeeping to achieve greater order, efficiency and discipline in the workplace. It is derived from the Japanese words Seiri (Sort), Seiton (Straighten), Seiso (Shine), Seiketsu (Systematize), and Shitsuke (Standardize\/ Self-Discipline). There are also different English renditions.\r\n\r\nThe 5Ss are:\r\n\r\n \tSort (Seiri) \u2013 The first step in 5S is to eliminate all the things in the workspace that are not being used and store them away. If a tool are material is not used on a daily basis, eliminate it from the workstation.\r\n \tSet in Order (Seiton) \u2013 The second step is to arrange the items used on a daily basis so that they can be easily accessed and quickly stored. Your goal is to make eliminate any unnecessary movements and actions by the worker to make hie process as efficient as possible.\r\n \tShine (Seiso) \u2013 Next is to get everything cleaned and functioning properly. The goal is to remove all the dirt and the grime and to keep it that way on daily basis. You want to get it clean and keep it clean.\r\n \tStandardize (Seiketsu) \u2013 The fourth step is to develop a routine for sorting, setting and shining. Standardize creates a system of tasks and procedures that will ensure that the principles of 5S are performed on a daily basis.\r\n \t\u00a0Sustain (Shitsuke) \u2013 In the last step, you want to create a culture that will follow the steps on a daily basis. The chief objective of sustain is to give your staff the commitment and motivation to follow each step, day in and day out.\r\n\r\n2. Suggestion System\r\n\r\nA Suggestion System is the method by which the ideas and suggestions of employees are communicated upwards through the management hierarchy to achieve cost savings or improve product quality, workplace efficiency, customer service, or working conditions. Examples range from simply placing suggestion boxes in common areas, to implementing formal programs with committees reviewing ideas and rewards given for successful adoption of those ideas.\r\n\r\n3. Quality Control Circle\r\n\r\nQCC is a small group of workers who collectively find a problem, discuss alternative remedies, and propose a solution. QCCs voluntarily perform improvement activities within the workplace, as part of a company-wide program of mutual education, quality control, self-development and productivity improvement.\r\n\r\n4. Total Quality control\r\n\r\nTQC is an organized activity involving everyone (from managers to workers) in a totally integrated effort towards kaizen at every level. It is equivalent to Company-Wide Quality Control (CWQC).\r\n\r\nTotal Quality Control is the system which Japan has developed to implement Kaizen or continuing improvement. Total Quality Control is a forty year plus improvement on the teachings of Deming, Juran, Feigenbaum, and others who brought the concept of quality to Japan. Total Quality Control is where the rubber meets the road in terms of putting quality into place, both within the product and within the system to bring forth, sustain, and retire the product.\r\n\r\n5. Total Quality Management (TQM)\r\n\r\nTQM represents a number of management practices, philosophies and methods to improve the way an organization does business, makes its products, and interacts with its employees and customers. QCC activities function as an integral part of TQM. TQM evolved from TQC in the late 1980s.\r\n\r\nTotal Quality Management (TQM) describes a management approach to long-term success through customer satisfaction. In a TQM effort, all members of an organization participate in improving processes, products, services, and the culture in which they work.\r\n\r\n6. Toyota Production System (TPS) \r\n\r\nTPS is the philosophy which organizes manufacturing and logistics at Toyota, including interaction with suppliers and customers. It focuses on the elimination of waste and defects at all points of production including inputs, process and final output (delivery). The term \u201cLean Production System\u201d can be used interchangeably.\r\n\r\nThe main objectives of the TPS are to design out overburden (muri) and inconsistency (mura), and to eliminate waste (muda). The most significant effects on process value delivery are achieved by designing a process capable of delivering the required results smoothly; by designing out \"mura\" (inconsistency). It is also crucial to ensure that the process is as flexible as necessary without stress or \"muri\" (overburden) since this generates \"muda\" (waste). Finally the tactical improvements of waste reduction or the elimination of muda are very valuable. There are eight kinds of muda that are addressed in the TPS\r\n\r\n \tWaste of overproduction (largest waste)\r\n \tWaste of time on hand (waiting)\r\n \tWaste of transportation\r\n \tWaste of processing itself\r\n \tWaste of stock at hand\r\n \tWaste of movement\r\n \tWaste of making defective products\r\n \tWaste of underutilized workers","headline":"Kaizen Tools &#8211; 5s, Suggestion System , QCC , TQC , TQM , TPS","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-03-04","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/03\/Kaizen-300x285-300x285.png","height":285,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/kaizen-continuous-improvement-definition-kaizen-process/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/03/kaizen-Process-300x187.jpg')"></div><span class="sr-only">link to Kaizen Continuous Improvement -Definition, Kaizen Process</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/kaizen-continuous-improvement-definition-kaizen-process/">Kaizen Continuous Improvement -Definition, Kaizen Process</a></p></header><div class="excerpt"><p>Kaizen Continuous Improvement -Definition, Kaizen Process

When a company adopts the Kaizen model, it strives to improve its processes in small but meaningful ways. And not just a onetime improvement, but a commitment to excellence by constantly testing and improving the work flow, day in and day out. Kaizen was first introduced in the Toyota manufacturing plant in Japan in the early 1950s, and it has since become one of the country\u201fs main reasons for its success. In Japan, kaizen is a way of life in the workplace, from the office of the CEO all the way down to shop apprentice. They take it very seriously, and for good reason. Kaizen has led them from a defeated wartime nation to one of the strongest industrialized countries in the world. But the best thing about kaizen \u2013 and the biggest reason that every company should adopt it \u2013 is that it does not rely on expensive innovative solutions. Just the opposite is true. The core principal of kaizen is to make small, immediate improvements in the processes and standards of the workplace. But not just one improvement.\r\n\r\nIn Japanese management, kaizen means \u201ccontinuous improvement\u201d involving the entire workforce from the top management to middle managers and workers. The origin of Japan\u201fs kaizen movement was the quality control method imported from the United States (US) in the post WW2 period. Japan assimilated and developed this as its own management practice method which later even surpassed performance in the US. This adapted method, which became known as kaizen, spread rapidly among Japanese companies including a large number of small and medium-sized enterprises. It subsequently spread overseas as Japanese business activities expanded abroad and Japanese companies began to build production networks with local companies.\r\nKAIZEN- THE DEFINITION \r\nKaizen (Kai \u201eZen) is a Japanese term that means continuous improvement, taken from words 'Kai', which means continuous and 'zen' which means improvement. Some translate 'Kai' to mean change and 'zen' to mean good, or for the better.\r\nKaizen is one of the most commonly used words in Japan. It is in the newspapers, on the radio and TV. Japanese society is bombarded daily with statements regarding the Kaizen of almost anything. In business, the concept of Kaizen is so deeply ingrained in the minds of both managers and workers that they often do not even realize that they are thinking Kaizen. The key difference between how change is understood in Japan and how it is viewed in the West lies in the Kaizen concept. This concept is so natural and obvious to many Japanese managers that they often do not even realize that they possess it! This explains why companies are constantly changing in Japan. The Kaizen concept is very weak in Western companies, where it is often rejected without knowing what it really entails. This explains why American and European factories may go years without changing.\r\n\r\nIn sport, the kaizen cycle leads to continual improvement in performance.\r\nKAIZEN IS A PROCESS\r\nkaizen Process\r\n\r\nTo understand what kaizen is, it may be helpful to look at the differences between the traditional western methods of improvement and kaizen in the west, innovation is king. When management wants to get better results from their workers, they introduce the latest technology, or incorporate the newest management technique that they saw at the last trade show. Big changes equal big results - that\u201fs the mantra that is traditionally chanted in the west. The result is often a big expenditure of money and time and in the end, the results are not that great. Kaizen is different. Kaizen is the tortoise compared to the western hare. It relies on long-term, long lasting and no dramatic changes. \u201cSmall steps done many times\u201d is the method that they rely on. It is a group effort \u2013 everyone is involved and contributing. It requires a small investment of money, but a large investment in effort, cooperation and training. If done correctly, the results are often amazing. Kaizen is a process. It is not a onetime adjustment made to make this quarter\u201fs numbers look better. It must become a daily part of every worker\u201fs routine. It must become part of the company\u201fs culture so managers and employees are constantly looking for small ways to improve the work flow. When that happens, you will have an organization that has become lean, mean and efficient. This is the essence of kaizen. This is its greatest strength.\r\nContinuous Improvement - Kaizen\u00a0\r\nIn any business, an employee\u201fs work is based on existing standards imposed by management. Improvement refers to improving those standards. The Japanese perception of management boils down to one precept to maintain and improve standards. Improving standards means establishing higher standards. Once this is done, it becomes management's maintenance job to see that the new standards are observed. Lasting improvement is achieved only when people work to higher standards. Maintenance and improvement have thus become inseparable for most Japanese managers. The higher up the manager is, the more he is concerned with improvement. At the bottom level, an unskilled worker working at a machine may spend all his time following instructions. However, as he becomes more proficient at his work, he begins to think about improvement. He begins to contribute to improvements in the way his work is done, either through individual suggestions or through group suggestions. Nobody can dispute the value of improvement. Whenever and wherever improvements are made in business, these improvements are eventually going to lead to improvements in such areas as quality and productivity. The starting point for improvement is to recognize need, and this comes from recognition of a problem. Kaizen emphasizes problem-awareness and provides clues for identifying problems.\r\n\r\nPROBLEM SOLVING \r\n\r\nKaizen starts with a problem or, more precisely, with the recognition that a problem exists. Where there are no problems, there is no potential for improvement. A problem in business is anything that inconveniences people downstream, either people in the next process or ultimate customers. The issue is that the people who create the problem are not directly inconvenienced by it, and therefore are not sensitive to problem. In day-to-day management situations, the first instinct, when confronted with a problem, is to hide it or ignore it rather than to face it squarely. This happens because a problem is a problem, and because nobody wants to be accused of having created the problem. By resorting to positive thinking, however, we can turn each problem into a valuable opportunity for improvement. Where there is a problem, there is potential for improvement. When a problem that has been identified must be solved. When a problem is solved and standards have been surpassed, then new standards must be set.","headline":"Kaizen Continuous Improvement -Definition, Kaizen Process","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-03-03","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/03\/kaizen-Process-300x187.jpg","height":187,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/micrometer-types-diagram-parts-read-micrometer/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/03/depth-micrometer-diagram-297x300.jpg')"></div><span class="sr-only">link to Micrometer &#8211; Types , Diagram , Parts , How to Read Micrometer</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/micrometer-types-diagram-parts-read-micrometer/">Micrometer &#8211; Types , Diagram , Parts , How to Read Micrometer</a></p></header><div class="excerpt"><p>Micrometer

In micrometer, the accurate screw and nut are used for measurement. The micrometers having good accuracy (about 0.01 mm), hence is used for most engineering precision work.\r\nPrinciple of micrometer\r\n\r\n \tMicrometers works on the principle of screw and nut. The screw is attached to a concentric cylinder or thimble the circumference of which is divided into a number of equal parts. We know that when a screw is turned through a nut by one revolution, its axial movement is equal to the pitch of the thread of a screw.\r\n \tIf I am pitch or lead of screw-in mm, each rotation of screw advances it in relation to the internal threads a distance equal to I mm. If the circumference of the concentric cylinder is divided into n equal divisions, movement (rotation) of a cylinder through one division indicates 1\/n rotation of the screw or 1\/n mm axial advance.\r\n \tIn millimeter micrometer instruments the screw has a pitch (lead) of 0.5 mm and thimble has 50 divisions so that the least count of the micrometer is equal to 0.5\/50 =mm. By reducing the pitch of the screw thread or by increasing the number of divisions on the thimble, the axial advance value per one circumferential division can be reduced and the accuracy of measurement can be increased.\r\n\r\nSee also:\u00a0Introduction To Engineering Metrology -Types Of measurements\r\n\r\nmicrometer diagram parts\r\nLeast count of micrometer\r\nLeast count of micrometer= pitch of the spindle screw \/ no of division in the spindle\r\nOutside micrometer parts :\u00a0\r\nThe figure illustrates an outside micrometer. It is used to measure the outside diameter and length of small parts to an accuracy of 0.01mm. The main parts of an outside caliper are:\r\n\r\n1. U shaped steel frame\r\n2. anvil &amp; spindle\r\n3. lock nut\r\n4. sleeve or barrel\r\n5. thimble\r\n6. ratchet\r\n\r\nmicrometer diagram\r\n\r\n1.U shaped steel frame\r\n\r\nThe outside micrometer has a U shaped or C shaped frame. It holds all the micrometer parts together. The gap of the frame permits the maximum diameter or length of the job to be measured. The frame is generally made of steel, cast iron, malleable cast iron, or light alloy. It is desirable that the frame of the micrometer be provided with conveniently placed finger grips of heat-insulating materials.\r\n\r\n2.Anvil and spindle\r\n\r\nThe micrometer has a fixed anvil protruding 3mm from the left-hand side frame. The diameter of the anvil is the same as the diameter of the spindle. Another movable anvil is provided on the front of the spindle. The anvils are accuracy ground and lapped with its measuring faces flat and parallel to the spindle. These are also available with WC faces. The spindle is the movable measuring face with the anvil on the front side. The spindle engages with the nut. It should run freely and smoothly throughout the length of its travel. There should be no backlash between the spindle screw and nut. There should be a full engagement of nut&amp; screw when the micrometer is at its full reading.\r\n\r\n3.Locknut\r\n\r\n \tA lock nut is provided on the micrometer spindle as shown in fig, to lock it when the micrometer is at its correct reading. \r\n \tThe design of the locknut is such that it effectively locks the spindle without altering the distance between the measuring faces. It thus retains the spindle in perfect alignment.\r\n\r\n4.Sleeve or Barrel:\r\n\r\nThe sleeve is accurately divided and clearly marked in 0.5mm division along its length which serves as the main scale. It is chrome plated and adjustable for zero settings.\r\n\r\n5.Thimble:\r\n\r\nThe thimble can be moved over the barrel, it has 50 equal divisions around its circumference.\r\n\r\n6.Ratchet:\r\n\r\n \tThe ratchet is provided at the end of the thimble. It is used to assure accurate measurement and to prevent too much pressure from being applied to the micrometer.\r\n \tWhen the spindle ratches near the work surface to be measured the operator uses the ratchet screw to tighter the thimble. The ratchet automatically slips when the correct (uniform) pressure is applied and prevents the application of too much pressure.\r\n\r\nRange Of Micrometer :\u00a0\r\nThe micrometer usually has a maximum opening of 25 mm. They are available in measuring ranges of 0 to 25 mm, 25 to 50 mm, 125 to 150 mm up to 575 to 600 mm.\r\nProcedure to take micrometer reading\r\nProcedure for measuring dimensions with the help of micrometer\r\n\r\n1. Select a micrometer with a desired range of measurement.\r\n2. Check the micrometer for zero error. It can be check by contacting the faces of anvil and spindle. The zero on the thimble should coincide with zero on the reference line on the barrel (main scale), as shown in Fig. If this does not happen, then zero error is present in the micrometer which must be accounted for in final readings.\r\n\r\nhow to check micrometer for zero error\r\n\r\n3. Hold workpiece which dimension to be measured between anvil and spindle as shown in Fig.\u00a0 Then make a final adjustment by rachet and lock it with the help of Jock nut.\r\n\r\nmicrometer cylinder diameter measurement\r\n\r\n4. Now, take the reading of the main scale, suppose main scale reading is 13 mm as shown in Fig. Take the thimble reading which coincides with the reference line on the barrel. The 35th division line is coincident with the reference line.\r\n\r\nmicrometer reading example\r\n\r\nTotal reading = Main scale reading + (L.C. x reading on thimble)\r\n= 13.5 + 0.01 X 35\r\n= 13.850 mm\r\nPrecautions to be taken while using a micrometer:\r\n1. The micrometer is available in various sizes and ranges, and the corresponding micrometer should be selected depending upon the size of the workpiece.\r\n2. Micrometer should be cleaned of any dust and spindle should move freely.\r\n3. Check and set the zero reading before measuring.\r\n4. The workpiece whose dimension is to be measured must be held in the left hand and micrometer in the right hand.\r\n5. Make sure that the dimension to be measured in parallel to the axis of the spindle and the anvil.\r\n6. Always use the rachet for final adjustment and locknut for taking readings.\r\n7. In case of measurement of diameter make sure that the anvil and spindle faces touch the maximum dimension only.\r\nSources of error in micrometers\r\n1. The faces of anvil and spindle may not be truly flat.\r\n2. Lack of parallelism and squareness of anvil or spindle at some or all parts of the scale.\r\n3. The setting of zero reading may be inaccurate.\r\n4. Inaccurate readings have shown by fractional divisions on the thimble.\r\n5. Wear on the faces of anvil &amp; spindle, and wear in the threads of the spindle.\r\n6. Error due to too much pressure on the thimble or not using the ratchet.\r\nTypes of Micrometers\r\nThere is a number of different micrometers available for specific application and accuracy.\r\n1. Outside micrometer\r\n2. Inside micrometer\r\n3. Vernier micrometer\r\n4. Depth micrometer\r\n5. Bench micrometer\r\n6. Digital micrometer\r\n7. Differential screw micrometer\r\n8. Micrometer with dial gauge\r\n9. Screw thread micrometer\r\nInside micrometer\r\n\r\n \tThe inside micrometer is used to measure the internal dimensions of the workpiece. Fig. 1.25 shows the inside micrometer, the construction is similar to the outside micrometer. However, the inside micrometer has no U-shape frame and spindle. The measuring tips are constituted by the jaws whose faces are hardened and ground to a radius.\r\n \tOne one of the jaw is held stationary at the end and the second one moves by the rotation of the thimble. The locking arrangement is provided with a fixed jaw. Fig. 1.26 shows another inside micrometer is used for a larger internal dimension. It consists of two anvils, sleeve, thimble, rachet, stop, and extension rods.\r\n\r\ninside micrometer diagram\r\n\r\n \tThe range of this micrometer is 50 mm to 210 mm. however, the range can be increased by anyone extension rod provided with it. This micrometer has no frame and spindle. The measuring points are at Extreme ends provided with anvils. The axial movement of endpoints is taken place by thimble rotation about the barrel axis.\r\n \tA series of extension rods are provided in order to obtain a wide measuring range. Before taking the measurement, the approximate internal dimension of a workpiece (whose dimension is to be measured by inside micrometer) is measured by a scale.\r\n \tThe extension rod is then selected to the nearest one and inserted in a micrometer head.\r\n \tThen, the micrometer is checked for zero error with the help of a standard-sized specimen whose internal dimension is known. The micrometer is then adjusted at a dimension slightly smaller than the internal (bore) diameter of the workpiece.\r\n \tThe micrometer head is then held finely against the bore as shown in Fig. 1.27 and other contact surface is adjusted by moving the thimble till the correct feel is sensed. The micrometer is then removed and reading is taken. The lengths of extension rod and collar are added to the micrometer reading.\r\n\r\nVernier micrometer\r\n\r\n \tIn order to increase accuracy, the vernier principle also is applied to an outside micrometer. This type of micrometer can be read by 0.001 mm length.\r\n \tThe vernier micrometer as shown in Fig.consists of three scales as follows:\r\n\r\nvernier micrometer diagram\r\n\r\n1. The main scale is graduated on the barrel with two sets of division marks. The set below the reference line reads in mm and set above the line reads in 1\/2 mm.\r\n2. A thimble scale is graduated on the thimble with 50 equal divisions. Each small division of thimble represents 1\/50 of a minimum division of the main scale. The main scale minimum division value is 1\/2 mm.\r\n3. Vernier scale is marked on the barrel. There are 10 divisions on the barrel and this is equivalent to 9 divisions on the thimble. Hence one division on a vernier scale is equal to9\/10thatofthimble. But one division on the thimble is equal to to0.01 mm. Therefore, one division on a vernier scale is equal to \r\n\r\nLeast count of vernier micrometer\r\n\r\nL.C. = Value of smallest division on thimble- Value of smallest division on the vernier scale.\r\n= 0.01 - 0.009\r\n= 0.001 mm\r\nHence the accuracy of the vernier micrometer is 0.001 mm.\r\n\r\nReading the vernier micrometer:\r\n\r\n Reading of vernier micrometer diagram\r\n\r\nMain scale reading= 11.5 mm\r\n\r\nThimble reading\r\n= No. of thimble division coinciding with reference line x L.C. of a thimble\r\n= 12 x 0.01\r\n= 0.12 mm\r\nThe 4th vernier scale line is coincident with the divisions of a thimble\r\n\r\nHence, vernier reading\r\n=No. of vernier division coinciding with thimble scale x L.C. of vernier\r\n= 6 x 0.001\r\n= 0.006 mm\r\nTotal reading= 11.5 + 0.12 + 0.006\r\n= 11.626 mm\r\n\r\nIf vernier line coincident with the reference line is 0, then no vernier reading added to the final reading.\r\nDepth micrometer\r\n\r\n \tDepth micrometer (micrometer depth gauge) is used to measure the depth of holes, slots and recessed areas.\r\n \tIt consists of a base (measuring face) which is fixed on the barrel and measuring spindle which is attached with thimble as shown in Fig. The axial movement of the spindle takes place by rotation of thimble.\r\n\r\n depth micrometer diagram\r\n\r\n \tThe measurement is made between the end face of the spindle and the measuring face of the base. As spindle moves away from the base, the measurement increases due to scales on the barrel are reversed from the normal.\r\n \tThe scale indicates zero when spindle flush with the face and maximum when the spindle is fully extended from the base Fig.shows the use of depth micrometer.\r\n \tThe main scale reading is 17. The 14th division line of the thimble match with the reference line. Hence, thimble reading is\r\nTotal reading= 17 + 0.14 = 17.14 mm\r\n \tThe depth micrometer is available in ranges 0 -25 mm or0-50 mm. The range can be increased up to 0-90 mm by using extension rods in steps of 25 mm. The extension rod can easily be inserted by removing the spindle cap.\r\n\r\nDifferential screw micrometer\r\n\r\n \tDifferential screw micrometer uses differential screw principle and hence the accuracy of -this micrometer is increased compared to an ordinary micrometer.\r\n \tIn this micrometer, the screw has two types of pitches as shown in Fig., one smaller and other larger, instead of one uniform pitch as in ordinary micrometer.\r\n\r\ndifferential screw micrometer diagram\r\n\r\n \tBoth the screws are right-handed and the screws are so arranged that the rotation of thimble, one screw. Moves forward and other moves backward. The anvil is not attached to the thimble, but it slides inside the barrel.\r\n \tThe smaller screw nut is fixed in the anvil while larger screw nut fixed with a barrel, hence screw rotates with the thimble. In the case of a metric micrometer, the normally employed pitch for the screws is 0.4 mm and 0.5 mm.\r\n \t\u00a0Therefore, one revolution of the thimble, the measuring anvil will advance by an amount equal to 0.5-0.4 = 0.1 mm. The thimble circumference is graduated in 100 equal divisions. Hence anvil moves in an axial direction by mm corresponding one division of thimble this micrometer has a smaller range due to small total axial movement (differential axial movement) of the spindle.\r\n\r\nDigital micrometer\r\n\r\n \tThe mechanical measuring device as micrometer and vernier are suitable for making measurements that are accurate within 0.001 mm. This device is inexpensive, lightweight, compact, and relatively rugged.\r\n \tBut when greater accuracy of measurement is desired, these mechanical devices are inadequate. In the case of digital or electronic instruments, measuring instruments having an electronic digital readout has become common in the industrial measuring instrument in order to get superior precision and ease of reading provided by the electronic digital readout.\r\n\r\ndigital micrometer diagram\r\n\r\n \tA digital micrometer consists of the frame, anvil, spindle, locknut, barrel, thimble, ratchet, LCD display, and ON\/OFF ZERO key as shown in Fig. It has incorporated a digital readout into the structure of the micrometer's body.\r\n \tThe digital readout is integrated with a rotary encoder that is capable of reading the axial displacement of a spindle which rotates as a thimble is rotated.\r\n \tThe digital micrometers are available in a large number of different sizes, normally 0-25 mm, 25-50 mm, 50- 75 mm, and 75-100 mm. They are used to measure length, diameter, or thickness.","headline":"Micrometer &#8211; Types , Diagram , Parts , How to Read Micrometer","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-03-02","mainEntityOfPage":"False","dateModified":"June 2, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/03\/depth-micrometer-diagram-297x300.jpg","height":300,"width":297},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/difference-pert-cpm-project-management/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/03/project-management-basic-terms-300x129.jpg')"></div><span class="sr-only">link to Difference between PERT and CPM &#8211; Project Management</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/difference-pert-cpm-project-management/">Difference between PERT and CPM &#8211; Project Management</a></p></header><div class="excerpt"><p>Difference between PERT and CPM - Project Management

That means projects are not repetitive.\r\n\r\nFew examples of projects are:\r\n1. Constructing a bridge, dam, highway or building.\r\n2. Producing an airplane, missile or large machine.\r\n3. Introducing a new product.\r\n4. Installing a large computer system.\r\n5. Redesigning the layout of plant or office.\r\n6. Construction of a ship.\r\n7. Fabrication of a steam boiler.\r\n8. Maintenance of major equipments\/Plants.\r\n9. Commissioning of a power plant\/factory.\r\n10. Conducting National Election.\r\n\r\nBasic steps in project management\r\nManaging a project, regardless of its size and complexity, requires identifying every activity to be undertaken and planning when each activity must begin and end in order to complete the overall project on time. Typically, all projects involve the following steps:\r\n1. Describe the project.\r\n2. Develop a network model.\r\n3. Insert time estimates.\r\n4. Analyze the model.\r\n5. Develop the project plan.\r\n6. Periodically assess the progress of the project and repeat steps 2-6 as needed.\r\n\r\nNetwork: A network is the graphical representation of the project activities arranged in a logical sequence and depicting all the interrelationships among them.\r\n\r\nproject management basic terms\r\n\r\nTerminologies used in Network diagram:\r\n\r\n1. Activity: An activity means work\/job. It is a time consuming process. It is represented by an arrow in the network diagram (AOA system).\r\n2. Event: An event is a specific instant of time marks the start and end of an activity.\r\n3. Critical path: It is the sequence of activities which decides the total project duration.\r\n4. Duration (d): Duration is the estimated or actual time required to complete a task or an activity.\r\n5. Total project time: Time to complete the project. In other words, it is the duration of critical path.\r\n6. Earliest start time (E): It is the earliest possible time at which an activity can start. It is calculated by moving from 1st to last event in the network diagram.\r\n7. Latest start time (Li): It is the latest possible time by which an activity can start.\r\n8. Earliest finish time (Ej): It is the last event time of the head event. It is calculated by moving backward in the network diagram.\r\n9. Latest finish time (Lj): It is the last event time of the head event. It is calculated by moving backward in the network diagram.\r\n10. Float\/Slack: Slack is with reference to an event and Float is with reference to an activity.\r\n11. Free float: (Latest Finish Time \u2013 Earliest Start Time) \u2013 Activity duration.\r\n\r\nNetwork scheduling\r\nThe biggest advance in project scheduling since the development of the Gantt chart in 1917 was made between1956-58. During this period, two new scheduling techniques were developed. These techniques are\r\n(i) Program evaluation and review technique (PERT)\r\n(ii) Critical path method (CPM)\r\n\r\nBoth are based on the use of a network\/graphical model to depict the work tasks being scheduled. The popularity of network based scheduling can be attributed to its many benefits, especially its ease use. Other benefits include the following.\r\n1. It provides a visual display of needed task and their temporal ordering, which makes it easy to see how tasks should be sequenced as shown below. This assists communication and co-operation among task teams because each team can see how its work affects other team.\r\n2. It provides a relatively accurate estimate of the time required to complete the project at the proposed resource level.\r\n3. It identified and highlights the tasks that are critical to keep the project on schedule.\r\n4. It provides a method for evaluating the time-cost tradeoffs resulting from reallocating resources among tasks.\r\n5. It provides a method for monitoring the project throughout its life cycle. As the project progresses, PERT\/CPM easily identifies change in which tasks are critical and how the expected completion date is affected.\r\n6. It provides a convenient method for incorporating uncertainty regarding task times into the schedule and it helps to evaluate the effect of this uncertainty on project completion time.\r\n\r\nDifference between PERT and CPM\r\n\r\n\n\n\n\n\tPERTCPM\n\n\n\n\n\tPERT is a probabilistic model with uncertainty in activity duration. Activity duration is calculated from t0, tp and tm.CPM is a deterministic model with well known activity duration.\n\n\n\tIt is an event oriented approach.It is an activity oriented approach.\n\n\n\tPERT terminology uses word like network diagram, event and slack.CPM terminology employs word like arrow diagram, nodes and float\n\n\n\tPERT terminology uses word like network diagram, event and slack.CPM terminology employs word like arrow diagram, nodes and float.\n\n\n\tThe use of dummy activity is required for representing the proper sequencing.No dummy activity required.\n\n\n\tPERT basically does not demarcate between critical and non-critical activities.CPM marks the critical activities.\n\n\n\tPERT is applied in projects where resources are always made available.CPM is applied to projects where minimum overall cost is the prime importance.\n\n\n\tPERT is suitable in Defence project and R&amp;D where activity time can\u2019t be readily predicted.Suitable for plant maintenance, civil construction projects etc. where activity duration is known.","headline":"Difference between PERT and CPM &#8211; Project Management","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-03-01","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/03\/project-management-basic-terms-300x129.jpg","height":129,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/operational-management-mba-course-graduation-mechanical-engineers/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/03/operation-research-introduction-300x174.jpg')"></div><span class="sr-only">link to Operational Management MBA &#8211; Course after Graduation For Mechanical Engineers</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/operational-management-mba-course-graduation-mechanical-engineers/">Operational Management MBA &#8211; Course after Graduation For Mechanical Engineers</a></p></header><div class="excerpt"><p>Operational Management MBA after Graduation For Mechanical Engineers

The contents and the boundaries of the OR are not yet fixed. Therefore, to give a formal definition of the term Operations Research is a difficult task.\r\n\r\nThe OR starts when mathematical and quantitative techniques are used to substantiate the decision being taken. The main activity of a manager is the decision making. In our daily life we make the decisions even without noticing them. The decisions are taken simply by common sense, judgment and expertise without using any mathematical or any other model in simple situations. But the decision we are concerned here with are complex and heavily responsible. Examples are public transportation network planning in a city having its own layout of factories, residential blocks or finding the appropriate product mix when there exists a large number of products with different profit contributions and production requirement etc.\r\n\r\nOperations Research tools are not from any one discipline. Operations Research takes tools from different discipline such as mathematics, statistics, economics, psychology, engineering etc. and combines these tools to make a new set of knowledge for decision making. Today, O.R. became a professional discipline which deals with the application of scientific methods for making decision, and especially to the allocation of scarce resources. The main purpose of O.R. is to provide a rational basis for decisions making in the absence of complete information, because the systems composed of human, machine, and procedures may do not have complete information.\r\n\r\nOperations Research can also be treated as science in the sense it describing, understanding and predicting the systems behaviour, especially man-machine system. Thus O.R. specialists are involved in three classical aspect of science, they are as follows:\r\ni) Determining the systems behaviour\r\nii) Analyzing the systems behaviour by developing appropriate models\r\niii) Predict the future behaviour using these models\r\n\r\noperation research introduction\r\nApplications of Operations Research\r\nToday, almost all fields of business and government utilizing the benefits of Operations Research. There are voluminous of applications of Operations Research. Although it is not feasible to cover all applications of O.R. in brief. The following are the abbreviated set of typical operations research applications to show how widely these techniques are used today:\r\n\r\nAccounting:\r\n\r\n \tAssigning audit teams effectively\r\n \tCredit policy analysis\r\n \tCash flow planning\r\n \tDeveloping standard costs\r\n \tEstablishing costs for byproducts\r\n\r\nConstruction:\r\n\r\n \tProject scheduling, monitoring and control\r\n \tDetermination of proper work force\r\n \tDeployment of work force\r\n \tAllocation of resources to projects\r\n\r\nManufacturing:\r\n\r\n \tInventory control\r\n \tMarketing balance projection\r\n \tProduction scheduling\r\n \tProduction smoothing\r\n\r\nMarketing:\r\n\r\n \tAdvertising budget allocation\r\n \tProduct introduction timing\r\n \tSelection of Product mix\r\n \tDeciding most effective packaging alternative\r\n\r\nOrganizational Behavior \/ Human Resources:\r\n\r\n \tPersonnel planning\r\n \tRecruitment of employees\r\n \tSkill balancing\r\n \tTraining program scheduling\r\n \tDesigning organizational structure more effectively\r\n\r\nPurchasing:\r\n\r\n \tOptimal buying\r\n \tOptimal reordering\r\n \tMaterials transfer\r\n \tResearch and Development:\r\n \tR &amp; D Projects control\r\n \tR &amp; D Budget allocation\r\n \tPlanning of Product introduction\r\n\r\nWhy most mechanical engineers go for an MBA in operations management?\r\n\r\nHowever to know why it is a natural one, let us see:\r\n\r\n \tMostly Mechanical engineers work in Manufacturing or related industry after they graduate, where they witness operations management at the floor level. They become the part of operations where they work. They either manage their sub-ordinates or get managed by their managers.\r\n \tMechanical engineering course already lay down the foundation for operations management by having Operations Research, Manufacturing Technology \/ Processes, Production Planning etc as courses. So as a graduate, you know the variable of the process \/ industry, and with Operations MBA, you get a chance to learn to manage them.\r\n \tA Mechanical engineer understands the significance of a supply chain more because s\/he can visualise (or has seen) it better as the parameters \/ constraints of a manufacturing floor are more or less similar in nature.\r\n \tThe target processes in Operations MBA during the course are quite similar to Mech processes like optimising a network, CPM \/ PERT, BIN system (KANBAN) etc.\r\n \tSo an MBA in Operations complements the engineering degree. As an engineer, you know the technical stuff about the process and as an Operations MBA, you know what to control and what matters most for the organisation.\r\n \tOperations management is best suited for those with an engineering background, especially for the Mechanical Engineers who are the most employed in a manufacturing industry environment.\r\n \tA Mechanical Engineer with a strong engineering background combined with Operations Management, where he learns Services Operation Management, Quality Management, Operation Research, Operations Strategy, Supply Chain Management, Project Management, Production &amp; Material Management and Business Modeling &amp; Simulation puts thrust on maximizing the efficiency of production and minimizing all round costs and the time to delivery of products to customer. Operations management team constantly strives to improve the effectiveness of processes.","headline":"Operational Management MBA &#8211; Course after Graduation For Mechanical Engineers","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-03-01","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/03\/operation-research-introduction-300x174.jpg","height":174,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/metrology-interview-questions-answers/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/03/METROLOGY-INTERVIEW-QUESTIONS-300x183.jpg')"></div><span class="sr-only">link to Metrology Interview Questions and Answers For Mechanical Student</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/metrology-interview-questions-answers/">Metrology Interview Questions and Answers For Mechanical Student</a></p></header><div class="excerpt"><p>Metrology Interview Questions and Answers For Mechanical Student

What are measurement standards?\r\nans. Standards are objects of known size, quantity, roughness, etc. These standards are used to calibrate and verify measuring instruments. As a result, measured values are more accurate.\r\n\r\n2. What effect will temperature variation have on precision measurements?\r\nans. Temperature control during measurement is important because as materials are heated they expand. Each material expands at a different rate. This leads to distortion of parts and measuring devices that results in measurement errors.\r\n\r\n3. How can a vernier scale provide higher accuracy?\r\nans. A vernier scale uses a second elongated scale to interpolate values on a major scale.\r\n\r\n4. What are dimensional tolerances, and what are their primary uses?\r\nans. Dimensional tolerances specify the amount a dimension may vary about a target value. These are supplied by a designer to ensure the correct function of a device. If these tolerances are controlled the final product will work as planned.\r\n\r\nMetrology interview question For Mechanical Students\r\n\r\n5. Why is an allowance different from a tolerance?\r\nans. A tolerance is the amount a single dimension can vary. An allowance is an intentional difference between two dimensions to allow for press fits, running fits, etc.\r\n\r\n6. What are fits?\r\nans. There are standard for different types of fits (e.g. press fit, running clearance). These specify the allowance of two parts, so that they may be made separately and then joined (mated) in an assembly.\r\n\r\n7. What is the difference between precision and accuracy?\r\nans. Precision suggests a limit of technology, accuracy is the ability to achieve a value consistently. These are often interchanged because we are usually concerned with the accuracy when producing precision parts.\r\n\r\n8. Why are different grades of gauge blocks used?\r\nans. There are different quality levels for gages blocks. The poorest sets are workshop grade and are more accurate than most machine tools. The best sets are very accurate, and must be kept in tightly controlled conditions. The bast sets are used for calibrating others.\r\n\r\n9. How are a ring gauge and a plug gauge different?\r\nans. A plug gage goes into a hole, a ring gage surrounds a dimension.\r\n\r\n10.\u00a0Why is a micrometer used for precise measurement of components in mechanical engineering?\r\nans : Digital calipers are pretty accurate, but if you need precision, a micrometer is the way to go. Some things need to be measured in 1\/10000ths of an inch (e.g. high pressure hydraulic pump pistons) and a digital caliper just won\u2019t do that. That said, I use calipers all the time and use a mic when I need to.\r\n\r\n11. How are pressure gauges specified?\r\nans : There are a number of things to take into account while specifying the right pressure gauge for your application. This goes from choosing the right measuring range, choosing the diameter of the dial, to preventing the pressure gauge from being subject to vibrations and even more of this kind of choices.","headline":"Metrology Interview Questions and Answers For Mechanical Student","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-03-01","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/03\/METROLOGY-INTERVIEW-QUESTIONS-300x183.jpg","height":183,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <nav class="pagination-wrapper" aria-label="article pagination"> <a class="prev page-numbers" href="?page_num=203">&laquo; PREV</a> <a class="page-numbers" href="?page_num=1"><span class="screen-reader-text">Page </span>1</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=202"><span class="screen-reader-text">Page </span>202</a> <a class="page-numbers" href="?page_num=203"><span class="screen-reader-text">Page </span>203</a> <span aria-current="page" class="page-numbers current"><span class="screen-reader-text">Page </span>204</span> <a class="page-numbers" href="?page_num=205"><span class="screen-reader-text">Page </span>205</a> <a class="page-numbers" href="?page_num=206"><span class="screen-reader-text">Page </span>206</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=338"><span class="screen-reader-text">Page </span>338</a> <a class="next page-numbers" href="?page_num=205">NEXT &raquo;</a></nav></section></main><aside id="secondary" class="widget-area"><div class="about-wrapper"><h2 class="widget-title" style="background: #d693c6; color: #ff392e">About Us</h2><div class="about-image" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2020/03/Sachin-Thorat-300x300-min.png')"></div><p class="about-copy">LearnMech.Com is a Mechanical Project-oriented platform run by Sachin Thorat who is a B-Tech Graduate in Mechanical Engineering.
