Objectives


The main objective of this course is to acquaint students with secondary manufacturing processes. In addition to their classification, this course includes physics of various secondary manufacturing processes. Further, the students will be introduced to working and control of manual and CNC machines besides measurement techniques used in manufacturing.

Course content


Introduction to manufacturing processes and system concept and its evolution; Metal casting: Solidification Mechanism, Gating and Riser Design, Defects and Product Design; Metal Forming: Fundamentals of Plasticity, Force Equilibrium Method, Forging/upsetting, Drawing, Extrusion, Deep Drawing and Bending, Defects; Machining: Tool Specifications, Orthogonal and Oblique cutting, Tool wear and Tool Life, Economics of Machining; Shaping processes for Plastics and Tool Design; Joining Processes; Un-Conventional Material Removal Processes: ECM, EDM, LBM and Jet Machining; Rapid Prototyping and Tooling; Micro-fabrication technologies; Metrology and Selection of Manufacturing Processes.
