Objectives
• To train the students in solid modelling, surface modelling and drafting
• To gain experience in assembly modelling, mechanism design and systems routing
• To practise computer controlled manufacturing methods
• To expose students to rapid prototyping
Solid Modeling - Creation of 3D models-Wireframe, Surface and Solid modeling techniques using CAD packages- Parametric modeling-Drafting-Generation of orthographic 2D views from models,Sectioning,Detailing –Exposure to Industrial components-Application of Geometrical Dimensioning &Tolerancing. Assembly Design Assembling of various machine parts and tolerance analysis, generation of 2D drawings and bill of materials from assembly Mechanism Design - synthesis and design of mechanisms - animations - exercises on various mechanisms like four bar chain, slider crank mechanism and its inversions System Design-Schematic and non schematic driven routing of pipes and tubes, Computer aided manufacturing Part programming fundamentals - manual part programming and computer aided part programming - hands on training in computer controlled turning and milling operations - tool path generation and simulation - exercises on CNC lathe and machining center/milling machines Generation of STL files and rapid prototyping of CAD models
