CAD/CAM

Sub Code : ME 701 Credits: 3:0:1 Prerequisite: Nil Preamble Computer Aided Design and Manufacturing (CAD/CAM) involves all the processes of conceptualizing, designing, analyzing, prototyping and actual manufacturing with Computer's assistance. Computer based information technologies have been extensively used to help both designing and manufacturing industries manage their processes and information system to focus their efforts on increasing the overall efficiency and meet the customer's requirements. CAD/CAM attempts to integrate the various stages of product design and development with a "Geometric Model", created from fundamentals of computational geometry (CG). Latest techniques of geometric modeling (Feature based or parametric modeling etc) and manufacturing like Rapid prototyping (RP) have bridged a gap between product conceptualization and product realization. A versatile Geometric Model can characterize all physical properties of real component and can incorporate all types of simulations and can quickly generate the modified outcomes (eg. Production drawings) for a predefined set of design rules. The benefits extend beyond design to engineering analysis, manufacturing and inspection which can be automated and integrated with the design. Present day CAD/CAM packages (Pro-E, ANSYS, Solid works, CATIA, Solid edge, Unigraphic's NX, NISA etc.) are capable of generating a versatile geometric model that can be used for simulation and evaluation of all probable practical conditions.
