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 plants 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 Dassaults 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 Dassaults Systems Solid Works Corp., a subsidiary of Dassaults Systems, S. A. (Vlizy, 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 moreenable 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.
