They had me make a part from a drawing, or physical object. By watching over your shoulder, that usually tells them all they need to know about your CAD experience and computer literacy.\r\nRemember that since every company has a different setup with their CAD software, PDM system, and documentation procedures, they\u2019re not worried about you doing the task perfectly. Usually they\u2019re watching to see what you do when you run into a task you don\u2019t know how to solve.\r\nThe biggest thing to do (and this is true for most interview questions, in my opinion) is to be honest about your skills and knowledge. If they want you to use the sheet metal tool in Solidworks, for example, but you haven\u2019t touched sheet metal tools in years, tell them that. They\u2019re expecting to have to train you to do things their way, show them that you\u2019re ready to listen instead of just trying to bluff through the test.\r\nRead also :AutoCAD And Drafting related interview Questions For Mechanical Students\r\nCAD Interview Question and Answers\r\n1 .\u00a0What is conceptualization in design process?\r\n\r\nA Concept Study is the stage of project planning that includes developing ideas and taking into account the all features of executing those ideas. This stage of a project is done to reduce the likelihood of assess risks, error and evaluate the potential success of the planned project.\r\n\r\n2.\u00a0Define concurrent engineering.\r\n\r\nIn concurrent engineering, various tasks are handled at the same time, and not essentially in the standard order. This means that info found out later in the course can be added to earlier parts, improving them, and also saving time.\r\nConcurrent engineering is a method by which several groups within an organization work simultaneously to create new products and services.\r\n\r\nSee also :\u00a0What is Concurrent Engineering ? benefits of Concurrent Engineering\r\n\r\n3.\u00a0.Describe Computer Aided Design.\r\n\r\nCAD is the function of computer systems to support in the creation, modification, analysis, or optimization of a design. CAD software is used to raise the productivity of the designer, progress the quality of design, progress communications through documentation, and to generate a database for manufacturing\r\n\r\nRead More :\u00a0\u00a0What is CAD | Types Of CAD | Computer Aided Design\r\n\r\n4.\u00a0State the importance of Computer Architecture in CAD.\r\n\r\nIn CAD, Computer architecture is a set of disciplines that explains the functionality, the organization and the introduction of computer systems; that is, it describes the capabilities of a computer and its programming method in a summary way, and how the internal organization of the system is designed and executed to meet the specified facilities.\r\n\r\n5.\u00a0What is \u2018Rendering\u2019?\r\n\r\nRendering is the making of a two dimensional image from a three dimensional model by means of computer programs. A picture file has objects in a strictly defined data structure; it would have information of geometry, lighting, viewpoint, texture, and shading as a description of the scene.\r\n\r\nRead More :\u00a0\u00a0What Is 3D Rendering - Best 3D rendering Software\r\n\r\n3d rendering\r\n\r\n6.\u00a0What do you understand by the term \u2018Texture Mapping\u2019?\r\n\r\nTexture mapping is a system for providing detail, surface texture and color to a computer generated graphic model. A texture map is used to the surface of a polygon. This process is like to sticking patterned paper to a plain white paper. Multi texturing is the use of more numbers of textures at a time on a polygon.\r\n\r\n7.\u00a0Write down \u2018Free form surface\u2019\r\n\r\nFreeform surface is used in CAD and other computer graphics software to describe the skin of a 3D geometric element. Freeform surfaces do not have rigid radial dimensions, unlike regular surfaces such as planes, cylinders and conic surfaces.\r\n\r\n8.\u00a0What is CGS ?\r\n\r\nConstructive solid geometry (CSG) is a method used in solid modeling for creating 3D models in CAD. Constructive solid geometry permits a modeler to make a complex surface by applying\r\nBoolean operators to join objects. Frequently CSG presents a model\/surface that appears visually complex, but is essentially little more than cleverly combined.\r\n\r\n9.\u00a0List out techniques of assembly modeling.\r\n\r\nBottom-up assembly model\r\nTop-down assembly model\r\n\r\nRead More :\u00a0\u00a0Design For Manufacturing and assembly - Overviews, Steps, Advantages\r\n\r\n10.\u00a0 list out the advantages of Tolerance Analysis\r\n\r\n1.

Reciprocating pumps are more suitable for low volumes of flow at high pressures.\r\nComponents of Reciprocating Pump\r\nThe main components of reciprocating pump are as follows:\r\n\r\n \tSuction Pipe\r\n \tSuction Valve\r\n \tDelivery Pipe\r\n \tDelivery Valve\r\n \tCylinder\r\n \tPiston and Piston Rod\r\n \tCrank and Connecting Rod\r\n \tStrainer\r\n \tAir Vessel\r\n\r\nreciprocating pump - Construction and application\r\n1. Suction Pipe\r\nSuction pipe connects the source of liquid to the cylinder of the reciprocating pump. The liquid is suck by this pipe from the source to the cylinder.\r\n2. Suction Valve\r\nSuction valve is non-return valve which means only one directional flow is possible in this type of valve. This is placed between suction pipe inlet and cylinder. During suction of liquid it is opened and during discharge it is closed.\r\n3. Delivery Pipe\r\nDelivery pipe connects cylinder of pump to the outlet source. The liquid is delivered to desired outlet location through this pipe.\r\n4. Delivery Valve\r\nDelivery valve also non-return valve placed between cylinder and delivery pipe outlet. It is in closed position during suction and in opened position during discharging of liquid.\r\n5. Cylinder\r\nA hollow cylinder made of steel alloy or cast iron. Arrangement of piston and piston rod is inside this cylinder. Suction and release of liquid is takes place in this so, both suction and delivery pipes along with valves are connected to this cylinder.\r\n6. Piston and Piston Rod\r\nPiston is a solid type cylinder part which moves backward and forward inside the hollow cylinder to perform suction and deliverance of liquid. Piston rod helps the piston to its linear motion.\r\n7. Crank and Connecting Rod\r\nCrank is a solid circular disc which is connected to power source like motor, engine etc. for its rotation. Connecting rod connects the crank to the piston as a result the rotational motion of crank gets converted into linear motion of the piston.\r\n8. Strainer\r\nStrainer is provided at the end of suction pipe to prevent the entrance of solids from water source into the cylinder.\r\n9. Air Vessel\r\nAir vessels are connected to both suction and delivery pipes to eliminate the frictional head and to give uniform discharge rate.\r\n\r\n\r\n\r\nWorking of Reciprocating Pump\r\nThe working of reciprocating pump is as follows:\r\n\r\n \tWhen the power source is connected to crank, the crank will start rotating and connecting rod also displaced along with crank.\r\n \tThe piston connected to the connecting rod will move in linear direction. If crank moves outwards then the piston moves towards its right and create vacuum in the cylinder.\r\n \tThis vacuum causes suction valve to open and liquid from the source is forcibly sucked by the suction pipe into the cylinder.\r\n \tWhen the crank moves inwards or towards the cylinder, the piston will move towards its left and compresses the liquid in the cylinder.\r\n \tNow, the pressure makes the delivery valve to open and liquid will discharge through delivery pipe.\r\n \tWhen piston reaches its extreme left position whole liquid present in the cylinder is delivered through delivery valve.\r\n \tThen again the crank rotate outwards and piston moves right to create suction and the whole process is repeated.\r\n \tGenerally the above process can be observed in a single acting reciprocating pump where there is only one delivery stroke per one revolution of crank. But when it comes to double acting reciprocating pump, there will be two delivery strokes per one revolution of crank.\r\n\r\nUses of Reciprocating Pump\r\nReciprocating pump is mainly used for\r\n\r\n \tOil drilling operations\r\n \tPneumatic pressure systems\r\n \tLight oil pumping\r\n \tFeeding small boilers condensate return\r\n\r\nAdvantages of Reciprocating Pump\r\n1. This pump is self-priming - Not require filling the cylinders by starting.\r\n2. This pump can work in wide pressure range.\r\n3. Priming is not necessary in pump.\r\n4. Provide high pressure at outlet.\r\n5. Provide elevated suction lift.\r\n6. They are use for air also.\r\n\r\nDisadvantages of Reciprocating pump\r\n1. Flow is not consistent, so we have to fit a bottle at equally ends.\r\n2. Flow is extremely less and cannot use for high flow process.\r\n3. High wear and tear, so need lot maintenance.\r\n4. Early price is much more in this pump.\r\n5. Additional heavy and large in shape.\r\n6. Low discharging capacity.","headline":"Reciprocating Pump &#8211; Construction and Working animation","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-02-10","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/02\/reciprocating-pump-Construction-and-application-300x149.jpg","height":149,"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/what-is-hydroblasting-application-of-hydroblasting/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/02/hydroblasting-300x225.jpg')"></div><span class="sr-only">link to What is Hydroblasting | Application of Hydroblasting</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/what-is-hydroblasting-application-of-hydroblasting/">What is Hydroblasting | Application of Hydroblasting</a></p></header><div class="excerpt"><p>What is Hydroblasting | Application of Hydroblasting

Abrasives, toxic and potentially harmful chemicals are not used in hydroblasting systems.\r\n\r\nA highly pressurized and focused stream of water, generally above 10,000 psi, comes from a hydro blasting machine, which includes a pressure pump and the right nozzles. This cleaning method may also require enclosures to protect the adjacent areas or structures from unwanted water spray as well as a collector or catcher of the blasted-off waste or contamination.\r\n\r\nHydroblasting is also called \"water blasting\".

In sheet metal operation the surface area-to-volume ratio of the starting metal is high. This ratio distinguished the sheet metal operation from bulk deformation. Often it is called press working because the machines used to perform these operations are pressed. A part produced by sheet metal operation is often called stamping.\r\nThe tools used to perform stamping operation are a set of tools called punch (smaller members) the upper half and a die (larger member) the lower half. The sheet metal is placed in between the two die halves. When the two die halves are brought together the punch enters the die and part\/s is\/are produced. Punch has a shape that corresponds to that of a die but is smaller by an amount determined by the required punch die clearance. Again the punch die clearance is determined by the type and thickness of the material and the operation to be\r\nperformed.\r\nSee also :\u00a0Classification Of Press Tools Operations related to Sheetmetal\r\nStamping of sheet metal involves cutting or shearing, bending or forming, and drawing or deep-drawing operations. A detail of all the process has been given below.\r\nBlanking or piercing: It involves cutting of the sheet metal along a close outline in a single step to separate the piece from the surrounding stock.\r\nForming: This operation produces one or more plane surfaces that are at an angle to the original or flat plane of the blank. Any change either small or big is classified as forming.\r\nDrawing: Forming of a flat metal sheet into a hollow or concave shape, such as a cup, by stretching the metal is known as drawing.\r\nShaving: It is a secondary operation after blanking or piercing operation. It produces a smooth edge on the work piece instead of the breakaway edge. This is achieved by removing a small amount of stock from the edge of the part.\r\nTrimming: It is similar to blanking but, it occurs after forming, drawing, or other operations when extra metal is left in the part for holding or locating purpose or as stock allowance. The removal of this extra stock is called trimming.\r\nEmbossing: It is used to create indentation in the sheet such as raised or depressed area with little or no change in material thickness. Making of nameplates and stiffening ribs are two applications\r\nCoining: It permits different designs to be imparted on either side of a blank. The blank is entirely captive in the die. Indentation results in thinning of the sheet metal and the raised sections result in thickening of the metal.\r\nSwaging: This process uses an open die. The part is also squeezed into cavity but in contrast to coining, the excess material is not contained but allowed to flow at will.\r\n\r\n\r\nmetal stamping\r\nCharacteristics and application of metal stamping\r\nIf the parts are designed properly, then this can contribute significantly to design for manufacturability (DFM). Other parts can be reduced by incorporating diverse function to the selected parts. Springs and other flexible sections, snap-fit elements, folding tabs, and pressfixable designs can be incorporated and can eliminate the need for other parts, including separate screw fasteners or other fasteners. Projection welding and spot welding are easily provided. Such innovations can reduce the number of parts in an assembly and make the stamped part itself easy to assemble.\r\nPerhaps the major characteristic of all stamped metal parts are of uniform wall thickness with few exception. The wall thickness ranges from a low of about 0.025 mm to about 20 mm, although pure bending or shearing operations are produced on even heavier stock. Most stamping, however, is performed in the range of about 1.3mm to 9.5mm stock thickness. The size of metal stampings ranges from the smallest parts used in wrist watches to large panels used in trucks or aircraft. The largest press brakes are as long as 9 m\r\nIn order to minimize die cost, the following guideline should be followed while designing parts for stamping manufacturing process: \r\n\r\n\r\n \tMinimize the number of distinct features in a part.\r\n \tAvoid closely spaced feature.\r\n \tAvoid the use of narrow cutouts and narrow projections.\r\n \tMinimize the number of bend stages in a part.\r\n \tBend angles greater than 90\u00b0 should be avoided if possible.\r\n \tAvoid side action feature.","headline":"What is Metal stamping &#8211; Stamping of sheet metal","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-02-10","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/02\/metal-stamping-300x216.jpg","height":216,"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=131">&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=130"><span class="screen-reader-text">Page </span>130</a> <a class="page-numbers" href="?page_num=131"><span class="screen-reader-text">Page </span>131</a> <span aria-current="page" class="page-numbers current"><span class="screen-reader-text">Page </span>132</span> <a class="page-numbers" href="?page_num=133"><span class="screen-reader-text">Page </span>133</a> <a class="page-numbers" href="?page_num=134"><span class="screen-reader-text">Page </span>134</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=133">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.
