Advanced Manufacturing and Process Modelling

By Prof. Prosenjit Das   |   IISc Bangalore
Learners enrolled: 822   |  Exam registration: 8
ABOUT THE COURSE:
Casting processes shape metal by pouring molten material into molds, addressing terminologies, patterns, gating design, risers, and defect remedies. Welding joins materials using various methods, considering joint types, weld metallurgy, mechanics, and defect remedies. Powder metallurgy forms parts from metal/ceramic powders, involving preparation, sintering, pressing, molding, and extrusion, with applications across various industries. Metal forming involves deformation techniques like forging, rolling, extrusion, and drawing, focusing on formability and defect analysis. Additive manufacturing is the advanced net shape manufacturing technology capable of yielding safety critical parts with dimensional accuracy and improved mechanical and physical properties. Machining is often the last step in manufacturing to meet the end goal of meeting dimensional requirements for the intended application of the developed part geometry. The present course will offer a comprehensive know how on process modelling of abovementioned manufacturing processes, in view of grabbing insight into the process physics as well as its optimisation and control.
