Transcript

  • 1. By Asstt. Prof. Abhay S. Gore Dept. of Mechanical Engg. MIT (T), Aurangabad Intro to CAD/CAM and Tools
  • 2. What is Design?  Design is the human power to conceive, plan, and realize products that serve human beings in the accomplishment of any individual or collective purpose.  Usually considered in the context of applied arts , engineering, architecture, and other creative endeavors
  • 3. Some Popular Design Approaches  User-centered design, which focuses on the needs, wants, and limitations of the end user of the designed artifact.  Use-centered design, which focuses on the goals and tasks associated with the use of the artifact, rather than focusing on the end user  KISS principle, (Keep it Simple, Stupid), which strives to eliminate unnecessary complications  Murphy's Law (things will go wrong in any given situation, if you give them a chance)
  • 4. CAD/CAM  Computer-aided design (CAD) is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design.  Computer-aided manufacturing (CAM) is the use of computer systems to plan, manage, and control the operations of a manufacturing plant through direct or indirect computer interface with plant’s resources.
  • 5. Need for CAD/CAM • To increase productivity of the designer • To improve quality of the design • To improve communications • To create a manufacturing database • To create and test tool paths and optimize them • To help in production scheduling and MRP models • To have effective shop floor control
  • 6. Tools of CAD/CAM  AutoCAD (CAD)  Computer Aided Design or Computer Aided Drafting  For 2D and 3D design and drafting, developed and sold by Autodesk, Inc. in 1982  Earlier primitive entities used such as lines, polylines, circles, arcs, and text  But now it has solid modeling and 3D tools  Has supported custom objects through its C++ API  Application Programming Interfaces (APIs) for customization and automation  Include AutoLISP, Visual LISP, VBA, .NET and ObjectARX
  • 7. AutoCAD
  • 8. CATIA (CAD/CAM/CAE):  Computer Aided Three-dimensional Interactive Application  By the French company Dassault’s Systems  Created in the late 1970s and early 1980s to develop Dassault's Mirage fighter jet  Adopted in the aerospace, automotive, shipbuilding, and other industries
  • 9. CATIA  Modules of CATIA  Product Structure  Part Design  Assembly Design  Sketcher  Drafting (Interactive and Generative)  Wireframe and Surface  Freestyle Shaper  Digital Shape Editor  Knowledge ware  Photo Studio  4D Navigator (including kinematics)  Manufacturing  Finite Element Analysis
  • 10. Pro/ENGINEER (CAD/CAM/CAE):  Is a parametric, integrated 3D CAD/CAM/CAE solution created by Parametric Technology Corporation (PTC).  First to market with parametric, feature- based, associative solid modeling software on the market  Solid modeling, assembly modeling and drafting, finite element analysis, and NC and tooling functionality for mechanical engineers
  • 11. Pro E
  • 12. SIEMENS NX (CAD/CAM/CAE):  NX is the commercial CAD/CAM/CAE PLM software suite developed by Siemens PLM Software.  Used in the engineering industry, especially in the automotive and aerospace sectors.  NX is a parametric solid / surface feature-based modeler  Uses the Para solid geometric modeling kernel.
  • 13. UG NX
  • 14. SOLID EDGE (CAD/CAE):  Intergraph in 1996 using the ACIS geometric modeling kernel it later changed to using the Para solid kernel  In 1998 it was purchased and further developed by UGS Corp  In 2007, UGS was acquired by the Automation & Drives Division of Siemens AG  Solid Edge is 3D CAD parametric feature solid modeling software  Provides solid modeling, assembly modeling and drafting functionality for mechanical engineers  It has links to many other Product Lifecycle Management (PLM) technologies
  • 15. Solid Edge
  • 16. SOLID WORKS (CAD/CAE):  Developed by Dassault’s Systems Solid Works Corp., a subsidiary of Dassault’s Systems, S. A. (Vélizy, France)
  • 17. INVENTOR (CAD/CAE):  Autodesk Inventor is a CAD software application for 3D mechanical design, product simulation, tooling creation, and design communication, developed and sold by Autodesk, Inc. in 1999
  • 18. MASTERCAM (CAD/CAM):  Founded in Massachusetts in 1983, CNC Software, Inc  Let machinists design virtual parts on a computer screen and also guided computer numerical controlled (CNC) machine tools in the manufacture of parts  It has set of predefined tool paths—  including contour, drill, pocketing, face, peel mill, engraving, surface high speed, advanced multi- axis, and  many more—enable machinists to cut parts efficiently and accurately
  • 19. MasterCAM
  • 20. DELCAM (CAD/CAM), EDGECAM (CAM), Work NC (CAM):
  • 21. Hypermesh (CAD/CAE)  Introduced by Altair Corporation  Generally modeling, for meshing the CAD model and analysis of CAD model  Have solver as Optistruct and RADIOSS
  • 22. ANSYS (CAE):  General-purpose finite element analysis and computational fluid dynamics software  Best known for its ANSYS Mechanical and ANSYS Multi physics products  Including static/dynamic structural analysis (both linear and non-linear), heat transfer and fluid problems, as well as acoustic and electro-magnetic problems.  CFX computational fluid dynamics and Fluent for CFD  Electronic design automation (EDA) software for to simulate high-performance electronics designs found in mobile communication and Internet devices, broadband networking components and systems, integrated circuits, printed circuit boards
  • 23. ANSYS
  • 24. SIMULIA (ABAQUS):  Developed by HKS Inc of Rhode Island, USA  Consists of three core products: Abaqus/Standard, Abaqus/Explicit and Abaqus/CAE. Abaqus/Standard
  • 25. Syllabus Term work shall Consists of record book on laboratory experiments studies on the following Sr. No. Practical 1. CAD exercises using any one drafting software 2.
