Jig body\r\nThe jig body supports the work piece and has locating and clamping elements in it. It is provided with four jig feets and rests on the machine table.\r\nii. Jig feet\r\na jig feet which is not bolted to machine table is provided with four jig feet, instead of the entire bottom surface lying flat on the machine table. Jig feet are either cast with the jig body or detachable or welded to the base. They are usually hardened and ground to have flat bottom.\r\niii. Jig bushing\r\nFor guiding drills, reamers and boring bars, hardened steel jig bushes are employed which are fixed in the jig plates. The bushes can be replaced when wornout with less cost than replacing the entire jig plate.\r\n\r\n\u00a0\r\n\r\niv. Jig plate or bush plate\r\nUsually the jig plate carries the jig bush for guiding the tools. The jig plate may be rigidly constructed as a single unit of jig or it may be of leaf or latch type. In this type, the jig plate must be clamped with the jig frame.\r\n\u00a0\r\nv. Locators\r\nLocators help a work piece to ret in proper position in a jig. Depending on the type of work piece, various types of locators are used for the locating the components, in the jig with reference to the tools, the locators are usually detachable type, fixed to the jig frame. So whenever wear occurs, the locators can be easily replaced with new ones.\r\n\r\nvi. Clamps\r\nClamps are used for holding the work piece rigidly against all disturbing forces. They also keep the work piece firmly in contact with locating pins of surfaces. Sufficient thickness of section should be provided to withstand clamping forces.\r\n\r\nvii. Fool proof element\r\nThis element prevents the work from being loaded wrongly into the jig. The elements may be simple fouling pegs, cross pieces or pins.","headline":"Main Parts  Of Jig and Fixture &#8211; Jig and Fixture Design","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2017-07-28","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2017\/07\/elementsofjigpartsofjigs-300x221.jpg","height":221,"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/design-consideration-for-glass-working/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2017/07/DesignConsiderationForGlassWorkingProductDesign-300x289.jpg')"></div><span class="sr-only">link to Design Consideration For Glass Working  Product  Design</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/design-consideration-for-glass-working/">Design Consideration For Glass Working  Product  Design</a></p></header><div class="excerpt"><p>Design Consideration For Glass Working  Product  Design  Glass products are commercially manufactured in an almost unlimited variety of shapes.

Many are produced in very large quantities, such as light bulbs, beverage bottles, and window glass. Others, such as giant telescope lenses, are made individually.\r\n\r\n\r\n\r\nDesign Consideration For Glass Working Product Design\r\n\r\n\u00a0\r\nGlassworking Product Design Consideration :\u00a0\r\nGlass possesses special properties that make it desirable in certain applications. The following design recommendations are:\r\n\r\n \tGlass is transparent and has certain optical properties that are unusual if not unique among engineering materials. For applications requiring transparency, light transmittance, magnification, and similar optical properties, glass is likely to be the material of choice. Certain polymers are transparent and may be competitive, depending on design requirements.\r\n \tGlass is several times stronger in compression than in tension; components should be designed so that they are subjected to compressive stresses, not tensile stresses.\r\n \tCeramics, including glass, are brittle. Glass parts should not be used in applications that involve impact loading or high stresses, which might cause fracture.\r\n \tCertain glass compositions have very low thermal expansion coefficients and are therefore tolerant of thermal shock. These glasses can be selected for applications in which this characteristic is important.\r\n \tOutside edges and corners on glass parts should have large radii or chamfers likewise, inside corners should have large radii. Both outside and inside corners are potential points of stress concentration.\r\n \tUnlike parts made of traditional and new ceramics, threads may be included in the design of glass parts; they are technically feasible with the press-and-blow shaping processes. However, the threads should be coarse.","headline":"Design Consideration For Glass Working  Product  Design","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2017-07-27","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2017\/07\/DesignConsiderationForGlassWorkingProductDesign-300x289.jpg","height":289,"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/designing-spring-diagra/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2017/07/DesigningMechanicalSprings-springdesigndrawing-300x204.jpg')"></div><span class="sr-only">link to General Steps in Designing Mechanical Springs</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/designing-spring-diagra/">General Steps in Designing Mechanical Springs</a></p></header><div class="excerpt"><p>General Steps in Designing Mechanical Springs   Springs and die springs are important mechanical components used in countless mechanisms, mechanical systems, and tooling applications.

This chapter contains data and calculation procedures that are used to design springs and that also allow the machinist, toolmaker or tool engineer, metalworker, and designer to measure an existing spring and determine its spring rate. In most applications, normal spring materials are spring steel or music wire, while other applications require stainless steel, high-alloy steels, or beryllium-copper alloys.\r\n\r\nSee also:\u00a0Types Of Mechanical Springs | Advantages and Applications Of Springs\u00a0\r\n\r\n\r\nMechanical Spring Design -Spring Diagram a. Compression Spring \u00a0b. Extension Spring\u00a0\r\n\u00a0Spring Design Procedures\r\n1. Determine what spring rate and deflection or spring travel are required for your particular application.\r\n2. Determine the space limitations the spring is required to work in, and try to design the spring accordingly using a parallel arrangement, if required, or allow space in the mechanism for the spring according to its calculated design dimensions.\r\n3. Make a preliminary selection of the spring material dictated by the application or economics.\r\n4. Make preliminary calculations to determine wire size or other stock size, mean diameter, number of coils, length, and so forth.\r\n5. Perform the working stress calculations with the Wahl stress correction factor applied to see if the working stress is below the allowable stress.\r\n\r\n\r\nThe working stress is calculated using the appropriate equation with the working load applied to the spring.The load on the spring is found by multiplying the spring rate times the deflection length of the spring. For example, if the spring rate was calculated to be 25 lbf\/in and the spring is deflected 0.5 in, then the load on the spring is 25 \u00d7 0.5 = 12.5 lbf.\r\n\r\nThe maximum allowable stress is found by multiplying the minimum tensile strength allowable for the particular wire diameter or size used in your spring times the appropriate multiplier. See the figures and tables in this chapter for minimum tensile strength allowables for different wire sizes and materials and the appropriate multipliers.\r\n\r\nEXAMPLE.\u00a0\r\nYou are designing a compression spring using 0.130-in-diameter music wire,ASTM A-228.The allowable maximum stress for this wire size is 0.45 \u00d7 258,000 = 116,100 psi\u00a0\r\n\u00a0\r\nNOTE. A more conservatively designed spring would use a multiplier of 40 percent (0.40), while a spring that is not cycled frequently can use a multiplier of 50 percent (0.50), with the spring possibly taking a slight set during repeated operations or cycles. The multiplier for torsion springs is 75 percent (0.75) in all cases and is conservative.\r\n\r\nIf the working stress in the spring is below the maximum allowable stress, the spring is properly designed relative to its stress level during operation. Remember that the modulus of elasticity of spring materials diminishes as the working temperature rises. This factor causes a decline in the spring rate. Also, working stresses should be decreased as the operating temperature rises.","headline":"General Steps in Designing Mechanical Springs","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2017-07-27","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2017\/07\/DesigningMechanicalSprings-springdesigndrawing-300x204.jpg","height":204,"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/advanced-rubber-tree-tapping-machine/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2017/07/AdvancedRubberTreeTappingMachineReportDownload-300x247.jpg')"></div><span class="sr-only">link to Advanced Rubber Tree Tapping Machine Report Download</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/advanced-rubber-tree-tapping-machine/">Advanced Rubber Tree Tapping Machine Report Download</a></p></header><div class="excerpt"><p>Advanced Rubber Tree Tapping Machine Report Download   Abstract   The objective of this paper is to obtain, inducing of mechanism of the farm is very crucial for the better agricultural output....</p><div class="button-container"><a rel="nofollow" class="button reverse" href="//www.gunkrazy.com/advanced-rubber-tree-tapping-machine/" aria-label="View Post: Advanced Rubber Tree Tapping Machine Report Download">View Post</a></div></div></div></article> <script type="application/ld+json">{"@context":"http:\/\/schema.org\/","@type":"BlogPosting","name":"Advanced Rubber Tree Tapping Machine Report Download","url":"\/\/www.gunkrazy.com\/advanced-rubber-tree-tapping-machine\/","articleBody":"Advanced Rubber Tree Tapping Machine Report Download\u00a0\r\n\r\nAbstract\u00a0\r\n\r\nThe objective of this paper is to obtain, inducing of mechanism of the farm is very crucial for the better agricultural output. Since Green revolution India is trying to modernize its agricultural outfits but had failed many times .As engineer it our primary duty to serve our country and help it in its up liftment.\r\nIn this project, mechanization of rubber tapping is done as it is rigorous and very difficult job. Our project can be used for extracting rubber latex from large number of trees with great ease. It would help in reduction of labor and would help in self-reliability of plantation owners for tapping. It is a machine which as a slider attached with a rotating tool to cut the cambium layer of rubber tree.\r\nThe slider is guided around the tree with help of the guide way. It would help labour to get away from back pain and other physical problems. It consists of a cordless drilling machine with a modified tool which can be simply operated with hand and with aid of a guide ways.\r\n\r\n\r\n\r\nINTRODUCTION\r\nIn India there is a demand for rubber as it is used for manufacturing products like Tyres, Tubes etc. The rubber is harvested from latex of rubber trees by undergoing may process. It is then vulcanized with sulphur to obtain vulcanized rubber which is used in tyre manufacturing industry. By a process called \u201crubber tapping\u201d we obtain rubber latex from tree. Here a helical cut is made in the tree, approximately four feet from the ground and circling about half the tree. Every day workers scrapes away the caked latex and a thin layer of bark in the early morning. The latex flows down the spiral into a cup for 2 hours before the sap hardens and closes the cut in the tree.\r\nCurrently the main problem facing the rubber industry is depreciation of the price of rubber and also lack of skilled workers. For tapping rubber trees care must be taken to avoid damaging the tree during tapping. Workers are trained for six months before learning the proper technique and improper tapping can kill many valuable trees. The process of tapping rubber is also a physically taxing job. To Improving this process would save cost of labour required for tapping. To improve this process we developed a new rubber tapping tool. A more economic design reduces worker fatigue. Through all of this the design is kept simple to keep reliability high and cost low.\r\n\r\n\r\n\r\nCONSTRUCTION AND WORKING PRINCIPLE\r\nII-A BODY FRAME\r\n\r\n\r\n\r\n\r\n \tIt the part which supports the rubber tapping machine.\r\n \tIt acts as the skeleton of the machine.\r\n \tIt helps in weight distribution of parts.\r\n\r\n\r\nII-B RUBBER BUSH\r\n\r\n\r\n\r\n\r\n \tIt helps in providing necessary friction for holding machine on tree.\r\n \tIt also prevents from damage the tree.\r\n\r\n\r\nII-C CLAMPING SCREW\r\n\r\n\r\n \tIt helps in holding and clamping the machine on tree.\r\n \tIt is similar to the nut and bolt mechanism.\r\n\r\nAdvanced Rubber Tree Tapping Machine Report Download\r\n\r\n\r\n\u00a0WORKING PRINCIPLE\r\nIt is a machine designed to obtain latex from the cambium layer of rubber tree. The main process happening here is that the tool is guided along the bark of tree with help of guide way. The tool is fitted on the slider. The slider is rested upon the guide way. The guide way plays a crucial role in the machine.\r\n\r\nWORKING PROCESS\r\nThe machine has a screw clamping mechanism for clamping the machine on the tree. After clamping, the rubber bush prevents damage to the bark of the tree. Then the slider is guided by the guide way to the spot where the tapping activity is to be carried. The depth of cut on the bark can be control by the hands. The cutting tool rotates in circular motion leads to the tapping or cutting of bark. The tool is given a force of 5 N\/mm.\r\n\r\n\r\n\r\nADVANTAGES\r\n\r\n\r\n\r\n\r\n \tIt can be used by common man.\r\n \tIn rubber plantations there will be various diameters of trees, in that case these machine will be useful.\r\n \tThe latex will be obtained very quickly and easily.\r\n \tLess effort is required.\r\n \tTo avoid the damage of tree, rubber bushes are placed on the frame\r\n\r\nAuthors:\r\n\r\n\r\nJ V C Maliackal, Asif K A, Sajith P A, Sajo K Joseph, Yazir\r\n\r\nDownload and Reference:\u00a0\r\nAdvanced Rubber Tree Tapping Machine Report Download\u00a0","headline":"Advanced Rubber Tree Tapping Machine Report Download","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2017-07-27","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2017\/07\/AdvancedRubberTreeTappingMachineReportDownload-300x247.jpg","height":247,"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/rotational-molding-working/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2017/07/RotationalMolding-WorkingPrinciple2CApplication2CAdvantages-300x285.jpg')"></div><span class="sr-only">link to Rotational Molding &#8211; Working Principle,Application , Advantages</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/rotational-molding-working/">Rotational Molding &#8211; Working Principle,Application , Advantages</a></p></header><div class="excerpt"><p> Rotational Molding - Working Principle , Application , Advantages, Disadvantages  Rotational Molding

The schematic of rotational molding process is shown in figure\r\n\r\nSee Also:\u00a0Introduction Of Blow Molding | Advantages And Disadvantages\r\nWorking Principle\r\nThe plastic material in the form of powder is inserted into the mold. The mold is heated in an oven and rotated biaxial until the powder has melted. The molten powder is adhered to the mold wall and makes a thin layer. The mold is opened and finished part is removed.\r\nThe mold is rotated at different speeds in order to avoid the accumulation of molten powder. The amount of time required to heat the powder at molten temperature in to the oven is important. If the oven is heated for long time, powder will degrade and it will affect the mechanical properties. If the mold is heated short time, the powder may not be completely melted, resulting in large bubbles in the powder. The formed part must be cooled through the air so that it solidifies slowly. The formed part will shrink on cooling, and facilitating easy removal of part. The cooling rate must be kept within a certain range.

The manipulator is based on a parallelogram linkage mechanism and translates along horizontal directions and z-axis motion i.e. vertical movement is provided by effective stylus length. At the end-effecter a palm router installed with milling cutter is mounted. Compared to conventional milling machine it can traverse the de-scaled profile traversed by stylus. The forward kinematic equations have been formulated. The simulation results by solid works software approximately matches the computation formulation derived in this paper. A prototype is made-up to perform milling operation on any contour. Pantograph Milling Machine is well explained below\r\n\r\n\r\nINTRODUCTION\r\nTraditional milling machine were able to mill only on a plain surface or we can say only along the straight paths and could not generate the replica of already existing object. This kind of manipulator has large workspace, high sleight and good maneuverability; it can be widely used in field of painting, welding, assembly and wood\/metal engraving. However due to its cantilever type structure, the manipulator is inherently not very rigid and thus the link connecting the assembly to the bed is the most vulnerable to failure due to bending load. It is poor in dynamic performance in high speed and heavy duty operations. Hence suitable for light duty and slow speed operations\r\n\r\nSince the parallel mechanism was first invented in 1960\u2019s and nowadays it is being used in many industrial applications. Light Rail vehicles (LRVs) are equipped with one pantograph that collects current from the contact wire. When the LRVs operate, the pantograph pan-head is in contact with the wire, and electricity is transferred to the vehicle\r\nThe mechanical efficiency of pantograph mechanisms and conventional open-chain and closed-chain type manipulators are studied and evaluated using the concept of modified geometric work. The kinematics of 6-DOF, pantograph type manipulators are studied and special: mechanisms which simplify the kinematics are introduced.\r\n\r\nThe computational complexity of both Cartesian and cylindrical type pantograph manipulators are evaluated and compared with a PUMA type manipulator\r\n\r\n\r\n\r\n\r\nThe Mechanism and Kinematics of a Pantograph Milling Machine\r\n\r\nThe pantograph mechanism is used to design and fabricate a milling machine which could traverse on any contour provided that stylus is moved along the same on any already existing object. Using such kind of manipulator we can generate the de-scaled replica of the object or we can say it to be a copying machine which can be employed in mass production with economical production\/machining cost. The 3-DOF in this manipulator adds a feature to increase or decrease the depth of engrave and thus can be used in metal engraving industries or wood carving industries to copy the engraved wooden design. At the end-effecter we can replace the cutter by a welding torch or a paint brush to\r\n\r\nperform the desired typical operation with very ease and accuracy. The only constraints are its poor dynamic performance but our kinematic analysis shows it to be perfect for light and slow speed operation.\r\n\u00a0\r\nAuthors:\r\n\r\nMahendra Verma, Abrar Ahmad, Niyazul S Haque, Sahil L Mallick, Ishank Mehta, R.
