What are the advantages of forging?\r\n\r\n1. It refines the structure of the metal\r\n2. It renders the metal stronger by setting the direction of the grains.\r\n3. It effects considerable saving in time, labour and material.\r\n\r\n5. Mention the tool and equipment used in hand forging.\r\n\r\nSmith\u2019s forge or hearth, Anvil, Swage block, Hammers, Tongs, Chisels, Punches, Fullers, Flatters,\r\n\r\n6. Mention the types of fire prepared in smith\u2019s forge.\r\n\r\n1. Open fire\r\n2. Stock fire.\r\n\r\n7. What do you mean by Open fire.\r\n\r\nOpen fire is prepared by covering the previously burnt coal by fresh coal in front of the tuyere. As combustion of fresh coal takes place and fire expands outwards, the coal from top and sides moves towards the centre f the hearth, and more fresh coal is added over the fire after removing the ash and clinkers etc. left behind by the previous fire.\r\n\r\n8. What is meant by stock fire.\r\n\r\nIs prepared for prolonged heating, for large components.\r\n\r\n9. Mention the role of Anvil during forging.\r\n\r\nAct as a supporting device for the components for which forging operation is carried out and is capable of withstanding heavy blows rendered to the job.\r\n\r\n10. Body of anvil is made of which material?\r\n\r\nBody is generally made of cast steel, wrought iron , mild steel provided with a hardened top, about 20 to 25mm thick.\r\n\r\n11. What is the use of Horn in Anvil?\r\n\r\nIs used in bending the metal or forming curved shapes. The flat step provided, between the top and the horn, is used to support jobs during cutting and is known as chipping block.\r\n\r\n12. What are Swage Block?\r\n\r\nIt carries a number of slots of different shapes and sizes along its four side faces and through holes from its top face to bottom face, which also vary in shapes and sizes.\r\n\r\n13. What is the function of Swage Block?\r\n\r\nUsed as a support in punching holes and forming different shapes. The job to be given a desired shape is kept on the similar shape slot.\r\n\r\n14. Swage Block is made from which material?\r\n\r\nUsually a block of cast steel or cast iron.\r\n\r\n15. What is the function of Hammers?\r\n\r\nHammers are used to give heavy blows to the job or component to be forged.\r\n\r\n16. From which material Hammers are made?\r\n\r\nGenerally Forged Steel.\r\n\r\n17. List the classification of hammers.\r\n\r\n1.Hand or Smith\u2019s hammers\r\n2.Sledge hammers\r\n3. Power hammers\r\n\r\n18. Mention the major parts of a Hammer.\r\n\r\nPein, Eye, Cheeks and face are the major parts of any hammer.\r\n\r\n19. Which is called as a Smith\u2019s hammer?\r\n\r\nBall pein hammer or a straight pein sledge type hammer of relatively samall size are called as Smith\u2019s hammer.\r\n\r\n20. What is the weight of a Ball Pein hammer?\r\n\r\nIts weight normally varies between 1 kg \u2013 1.8kg.\r\n\r\n21. What is a Ball Pein hammer?\r\n\r\nIs used for all general work and its pein is employed when slight blows at a faster speed are needed such as in fullering a rivet head in a countersunk hole.\r\n\r\n22. What are Sledge Hammers?\r\n\r\nAre comparatively 3 to 4 times heavier than the hand hammers. They are available in varying sizes and weights from 3 kg \u2013 8 kg.\r\n\r\nsledge Hammers\r\n\r\n23. When we need a Sledge Hammer\r\n\r\nWhen heavy blows are needed in forging and other operations done on heavy jobs.\r\n\r\n24. List the classification of Sledge Hammer.\r\n\r\n1. Straight pein hammer\r\n2. Cross pein hammer\r\n3. Double faced sledge hammer.\r\n\r\n25. What is the function of Tongs?\r\n\r\nThey are used to hold the jobs in position and turning over during forging.\r\n\r\n26. From which material Tongs are made?\r\n\r\nThey are made of Mild Steel.\r\n\r\n27. Mention the size of Tongs used during forging.\r\n\r\nSizes of the tongs vary according o the size and shape of the job to be held, but the commonly used lengths of the tongs in hand forging vary from 40 to 60cm with the jaws opening ranging from 0.6 to 5.5 cm.\r\n\r\n28. List the types of Tongs\r\n\r\nThey are Close flat tong, Side bit tong, Pincer tong, Chisel or belt tong, Round hollow tong, Square hollow tong, Pickup tong.\r\n\r\n29. What is the function of Chisels?\r\n\r\nChisels are used to cut metals in hot or cold state. Those which are jused for cutting the metal in hot state are termed as hot chisels. When used for cutting in cold state are known as cold chisels.\r\n\r\n30. What is the difference between Hot &amp; Cold chisel?\r\n\r\nThe main difference between these chisels is in the included angle at the cutting edge.\r\n\r\n31. What is the included angle for cold chisel?\r\n\r\nA cold chisel carries an included angle of 60 degree at the cutting edge.\r\n\r\n32. What is the included angle for Hot chisel?\r\n\r\nA hot chisel carries an included angle of 30 degree at the cutting edge\r\n\r\n33. Mention the materials from which cold &amp; hot chisels are made?\r\n\r\nCold chisels are made from High carbon steel, where as Hot chisels are made from Medium carbon steel.\r\n\r\n34. What are punches?\r\n\r\nPunches are tapered tools made in various shapes and sizes. They are used for producing holes in red hot jobs.\r\n\r\n35.

Name three things about a feature that you can not redefine.\r\n\r\nThe class (solid, datum, and surface), the type (protrusions or cut), the form (extrude, revolve, sweep, and blend).\r\n\r\n62. Name three things about a feature that you can redefine.\r\n\r\nEverything in the dialog box (attributes (one-sided, both sides), sketch, direction, material side, depth, etc.).\r\n\r\n63. Can a feature be reordered before any of its parents?\r\n\r\nNo, never.\r\n\r\n64. Explain the difference between insert mode and suppressing features.\r\n\r\nInsert mode allows you to add features to the model before existing features and have the existing features move down in the model tree. Suppress removes features temporarily, but when they resume, they come back to their original position in the model tree.\r\n\r\n65. List three reasons to suppress features.\r\n\r\nTo simplify the model, to speed regeneration. To try different design iterations (what-if scenarios). To reduce file size for transfers thru email or floppy disks, etc.\r\n\r\n66. Can a feature with children be suppressed?\r\n\r\nYes, if you are willing to suppress the children as well.\r\n\r\nPro Engineer PTC Software Interview Question and Answers Part 3\r\n\r\n67. Explain parent\/child relationships.\r\n\r\nFeatures reference the parents for definition. Example, the sketching plane of an extruded protrusion is it\u2019s first parent. The protrusion is the child of the sketching plane, etc.\r\n\r\n68. What is \u2018Component Display\u2019?\r\n\r\nComponent display is used to show components in an assembly in different display modes. (Wireframe, hidden line, no hidden, shaded, or not shown at all).\r\n\r\n69. How do you find parent\/child relationships?\r\n\r\nUse info, global, reference viewer.\r\n\r\n71. What are the steps required to get just one components default datum planes displayed in an assembly?\r\n\r\nUsing layers, blank the layer containing the default datum planes, pick the plus sign next to that layer in the layer display dialog box and then pick the component that you want to see the planes in and then pick the show icon.\r\n\r\n72. Why would you do this?\r\n\r\nTo be sure that when creating a feature, you are using the datum planes in that part so that you don\u2019t make unwanted external references (parent\/child relationships).\r\n\r\n73. What does \u2018save status\u2019 in the layer menu do?\r\n\r\nSave status permanently sets the layer displays status of the model so that when the model is saved and opened again the layer display is still set that way.\r\n\r\n74. What function in layers should you not use?\r\n\r\nIt is normally recommended that beginners not use the isolate function in layer display.\r\n\r\n75. When copying a feature, what is the difference between \u2018dependent\u2019 and \u2018independent\u2019?\r\n\r\nDependent means that the copy feature will change when the original feature is changed. Independent means that the new feature will not change when you change the original feature.\r\n\r\n76. What is different about a feature that has a dependent copy?\r\n\r\nWhen redefining a feature that has a dependent copy, the alignment function in the sketcher is not available.\r\n\r\n77. How do you make a dependent copy feature independent from its original feature?\r\n\r\nUse modify, make independent.\r\n\r\n78. What is the pro_group_dir for?\r\n\r\nThis configuration option is used to tell the system where you are keeping your udf\u2019s.\r\n\r\n82. What is a cosmetic thread and why is it used?\r\n\r\nA cosmetic thread is a special surface feature that is used to define threads in models. It is only a cosmetic feature and does not affect mass properties. On drawings these features display like you normally want them to for a threaded hole.\r\n\r\n83. How do you create an opposite hand (mirror image) part?\r\n\r\nCreate an assembly without datum planes. Assemble the part that you want to make a mirror of. Pick component, create, part, mirror. Enter a name for the new part, pick ok, and select a datum plane in the part for the mirror plane.\r\n\r\n84. How do you get a bill of materials list of the components in an assembly?\r\n\r\nUse info bom.\r\n\r\n85. How do you modify a \u2018mate offset\u2019 dimension?\r\n\r\nPick modify, pick the component, pick the dimension, enter a value, pick regenerate, automatic\r\n\r\n86. When do you use two equal signs in a relation?\r\n\r\nWhen testing for equality.\r\n\r\n87. When do you use one equal sign in a relation?\r\n\r\nWhen setting equality (making one thing equal to another).\r\n\r\n88. What does \u2018ceil 10.2\u2019 evaluate to?\r\n\r\n11\r\n\r\n89. What does \u2018floor 25.8\u2019 evaluate to?\r\n\r\n25\r\n\r\n90. When do part relations evaluate?\r\n\r\nAt the beginning of regeneration before any features are regenerated.\r\n\r\n95. Why should you comment relations?\r\n\r\nYou should comment relations so that other users can understand what you are trying to accomplish with the relations.\r\n\r\n96. What does \u2018sort relations\u2019 do?\r\n\r\nSorts the relations in case of circular references within the relations.\r\n\r\n97. Can you add motion to a part?\r\n\r\nYes.\r\n\r\n98. How do you add a model parameter in a drawing note?\r\n\r\nUse ampersand and then the parameter name (&amp;material).\r\n\r\n99. What is the difference between #Move and #Move Text?\r\n\r\n. Move allows you to move the selected item anywhere. Move text allow you to move the selected item only parallel to the elbow\r\n\r\n100. Name the four types of tolerance formats?\r\n\r\nNominal (no tolerance shown), plus\/minus, plus\/minus symmetric, limits.\r\n\r\n101. Which of the tolerance formats should you not use?\r\n\r\nPlus\/minus (because manufacturing people want the model at the mean size not the nominal size).\r\n\r\n102. What is a drawing symbol?\r\n\r\nA symbol is a collection of draft entities that are stored together for reuse on other drawings\r\n\r\n103. Can a drawing reference more than one assembly?\r\n\r\nYes.\r\n\r\n\r\nProE Wildfire interview Question and Answers : Part 1 \u00a0| Part 2 \u00a0| Part 3\u00a0\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nCAD Software | CAD Tutorials\r\nTechnical Mechanical Interview Question and Answers\r\nCAD \/ CAM Projects List - Abstract , Report Download\r\nStructural analysis and Design 3d Model Projects\r\n\r\n\r\n\r\n&nbsp;","headline":"Pro Engineer PTC Software | Interview Question and Answers Part 3","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-05-22","mainEntityOfPage":"False","dateModified":"February 18, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/05\/Pro-Engineer-PTC-Software-Interview-Question-and-Answers-Part-3-300x213.jpg","height":213,"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/pro-engineer-ptc-software-interview-question-and-answers-part-2/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/05/Pro-E-Interview-Question-and-Answers-300x194.jpg')"></div><span class="sr-only">link to Pro Engineer PTC Software | Interview Question and Answers Part 2</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/pro-engineer-ptc-software-interview-question-and-answers-part-2/">Pro Engineer PTC Software | Interview Question and Answers Part 2</a></p></header><div class="excerpt"><p>Pro Engineer PTC Software | Interview Question and Answers Part 2

What is the minimum number of surfaces you must remove when adding a shell feature?\r\n\r\nOne.\r\n\r\n32. What is the minimum number of sections you must sketch when adding a blend feature?\r\n\r\nTwo.\r\n\r\n33. What is the difference between a \u2018straight\u2019 and \u2018smooth\u2019 blend feature?\r\n\r\nStraight extrudes with straight segments between the sections. Smooth extrudes with the best fit arc between three or more sections.\r\n\r\n34. What is the first section of a sweep feature called?\r\n\r\nTrajectory.\r\n\r\n35. What does the start point and direction arrow do in a blend feature?\r\n\r\nThe start point determines where the system starts counting the vertices in the section.\r\n\r\n36. What does a \u2018blend vertex\u2019 do?\r\n\r\nA blend vertex adds one additional vertex to the sketch, for example, when blending between a rectangle and a triangle a blend vertex is required on the triangle section so that the sections have the same number of vertices.\r\n\r\nPro E Interview Question and Answers\r\n\r\n37. Why is alignment not always necessary when creating the cross section of a sweep feature?\r\n\r\nBecause the system draws two sketcher centerlines, and if you sketch close enough to the centerlines, the system will assume alignment.\r\n\r\n38. What are the three types of dimensional patterns?\r\n\r\nIdentical, varying, general.\r\n\r\n39. What is the requirement for a feature to be patterned?\r\n\r\nThe feature must have a locating dimension.\r\n\r\n40. Which of the three types of dimensional patterns regenerates fastest? \r\n\r\nIdentical.\r\n\r\n41. What is a reference pattern?\r\n\r\nA pattern that follows another pattern.\r\n\r\n42. How do you control the number of turns in a helical sweep feature?\r\n\r\nYou can\u2019t, directly. The number of turns is the length of the trajectory divided by the pitch.\r\n\r\n43. How do you add a mapkey to a pull-down menu?\r\n\r\nUse utilities, customized screen and pick the menus tab, then pick the menu, then pick the mapkey, then pick the arrow, then pick ok.\r\n\r\n44. How do you add an icon to a toolbar?\r\n\r\nUse Utilities, Customize Screen, and pick the 'Commands' tab. Select in the categories panel and then drag the icons to the toolbars.\r\n\r\n45. What is the \u2018Intent Manager\u2019?\r\n\r\nThe new sketcher where the section is always regenerated.\r\n\r\n46. List three uses for datum curves.\r\n\r\nTo create a layout. To define an area on the part that is not really a solid feature, for example, where to apply a label to the part. To develop kinematic mechanisms\r\n\r\n48. What text should not be edited in the drawing title block?\r\n\r\nThe tolerances, the scale, the number of sheets, just about everything except your name and the date, because they are all driven by parameters coming from the part.\r\n\r\n49. How do you change the tolerance values in the drawing title block?\r\n\r\nChange the tolerances in the part which can be displayed using the environment menu under utilities.\r\n\r\n50. If a drawing view is added with the \u2018no scale\u2019 option, does it really have no scale?\r\n\r\nNo, it uses the sheet scale.\r\n\r\n51. What type of view must the first view added to a drawing be?\r\n\r\nGeneral, and you must orient it using save views from the model.\r\n\r\n52. Why should you use #Disp Mode on drawing views?\r\n\r\nBecause by default, drawing views get their hidden line removal from the environment. Each users environment may be different thus causing the drawing views to look different when another user opens the drawing.\r\n\r\n53. What is a \u2018shown\u2019 dimension?\r\n\r\nA dimension from the model.\r\n\r\n54. If you erase a dimension, is it gone forever?\r\n\r\nNo\r\n\r\n55. Why is it a good idea to start drawings early in the part design?\r\n\r\nBecause it\u2019s easier to show the dimensions from the model a few features at a time. Start the drawing early and have the drawing process be a parallel process with creating the part. In other words, create a couple features, go to the drawing, show the dimensions from the feature on the drawing, go back to the model, create a couple more features, show those dimensions on the drawing, etc.\r\n\r\n56. What is the best way to show dimensions?\r\n\r\nUse preview and pick the features from the model tree.\r\n\r\n57. How are the default number of decimal places and default tolerance values determined for parts and assemblies?\r\n\r\nThey are built into the start part and start assembly.\r\n\r\n59. Why should you put assembly components on a layer?\r\n\r\nSo you can see to add new components to the assembly. Layers do not care about parent\/child relationships.\r\n\r\n60. How do you get a list of all the features in a model?\r\n\r\nUse info feature list.\r\n\r\n&nbsp;\r\n\r\n\r\nProE Wildfire interview Question and Answers : Part 1 \u00a0| Part 2 \u00a0| Part 3\u00a0\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nCAD Software | CAD Tutorials\r\nTechnical Mechanical Interview Question and Answers\r\nCAD \/ CAM Projects List - Abstract , Report Download\r\nStructural analysis and Design 3d Model Projects\r\n\r\n\r\n\r\n&nbsp;","headline":"Pro Engineer PTC Software | Interview Question and Answers Part 2","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-05-22","mainEntityOfPage":"False","dateModified":"February 18, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/05\/Pro-E-Interview-Question-and-Answers-300x194.jpg","height":194,"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/pro-engineer-ptc-software-interview-question-and-answers-part-1/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/05/PROE-interview-question-and-Answers-300x163.jpg')"></div><span class="sr-only">link to Pro Engineer PTC Software  | Interview Question and Answers Part 1</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/pro-engineer-ptc-software-interview-question-and-answers-part-1/">Pro Engineer PTC Software  | Interview Question and Answers Part 1</a></p></header><div class="excerpt"><p>Pro Engineer PTC Software | Interview Question and Answers Part 1

What is the difference between object reference and geometric associativity?\r\n\r\nObject reference is a data management term that has to do with the way one object references another. Geometric associativity has to do with how a parts geometry can be changed from the part or drawing.\r\n\r\n2. What are the file extensions given to parts? assemblies? drawings? sketches?\r\n\r\nParts: .prt - Assemblies: .asm - Drawings: .drw - Sketches: .sec\r\n\r\n3. How should you create a new part or assembly? Why?\r\n\r\nYou should always create a new part or assembly using the copy from option in the new dialog box and copy a start part. This ensures the proper layer setup, saved views, datum planes, parameters, etc\r\n\r\n4. What is the config.pro file used for?\r\n\r\nThe config.pro file contains configuration options which control the behavior of pro\/engineer. This file also contains user macros which are called mapkeys\r\n\r\n5. What is a trail file?\r\n\r\nThe trail file is a record of every menu pick and screen pick and keyboard input during an entire session of pro\/engineer. This file can be retrieved and edited and replayed to retrieve work lost during an unexpected failure of a session.\r\n\r\n6. What does \u2018store back\u2019 mean?\r\n\r\n'Store back' refers to the behavior in which an object is stored back to the directory from where it was opened not necessarily the current working directory.\r\n\r\n7. What is the difference between File, Erase and File, Delete?\r\n\r\nFile erase removes the object from the ram of the computer and file delete removes the object from the disk or hard drive of the computer.\r\n\r\n8. What is the difference between File, Save and File, Backup?\r\n\r\n. File save stores the object in the directory where it was opened from and file backup copies the object to the specified directory using the same name\r\n\r\n9. After performing a File, Save As, what is the current object?\r\n\r\nAfter performing a file save as command the current object is not a new object it is the old object\r\n\r\n10. If I use Window, Close without saving my model, have I lost my work?\r\n\r\nNo.\r\n\r\n11. If I use File, Erase without saving my model, have I lost my work?\r\n\r\nYes.\r\n\r\n12. What is a feature?\r\n\r\nA feature is a geometric definition of part of the model.\r\n\r\nPROE interview question and Answers\r\n\r\n13. (True or False) All features have parents. Explain.\r\n\r\nTrue, with the exception of the three default datum planes. All features reference other features for their definition thus creating parent\/child relationships\r\n\r\n14. (True or False) All features have children. Explain.\r\n\r\nFalse. Example, rounds and chamfers should not have children.\r\n\r\n15. (True or False) Parent child relationships are bad. Explain\r\n\r\n. False. Parent\/child relationships are bad if you are not aware of how they are created.\r\n\r\n16. Can parent child relationships be broken?\r\n\r\nYes, using Redefine or Reroute.\r\n\r\n17. What is the mouse button sequence to query select an object that is under another object?\r\n\r\nRight, left to pick, right as many times as you need to to get the thing you want, middle to except the thing you want, middle again for done select.\r\n\r\n18. What is a reference plane? What does #Default do?\r\n\r\nThe reference plane gives the sketching plane it\u2019s orientation. Using default, the system picks the reference plane for you and does not create a parent\/child relationship.\r\n\r\n19. What does a sketch point do?\r\n\r\nA sketch point is used as a construction entity to help constrain a sketch.\r\n\r\n20. What do a construction circle and a sketch centerline do?\r\n\r\nA construction circle and a sketched center line are used to help define your design intent.\r\n\r\n21. Name six common assumptions the sketcher will make.\r\n\r\nHorizontal and vertical, equal length lines, equal radius or diameter, co-linearity, 90 and 180 degree arcs, points on the same horizontal or vertical, points on other entities, tangency, symmetry, parallel and perpendicular lines.\r\n\r\n22. What is the difference between #One Side and #Both Sides?\r\n\r\nOne-side extrudes only one specified direction from the sketching plane. Both sides extrudes both sides of the sketching planes.\r\n\r\n23. How do you change dimensions of a feature?\r\n\r\nModify, pick the feature, pick the dimension, enter the new value, pick regenerate.\r\n\r\n 25. Define \"Parametric Feature Based Modeling\".\r\n\r\nParametric means driven by parameters. Feature based means you define a series of instructions (features) to tell the system your design intent. Modeling means creating computer images coupled with geometric information defining a part or assembly.\r\n\r\n26. What is different about datum planes created \u2018on the fly\u2019?\r\n\r\nThe datum plane created on the fly means it was created when you were in the middle of creating something else and it goes away after the thing you really wanted was created. These are created using the 'make datum' command.\r\n\r\n27. List five uses for datum planes.\r\n\r\nSketching plane, reference plane, dimension and alignment references, geometric tolerancing, creating cross sections.\r\n\r\n28.
