UNIT – VI : (Learning Objective: To make the students aware of specialized forming processes and their specific applications to improve their analytical and simulation skills) Sheet Metal Forming and Other Processes
Forming methods – Shearing, blanking, bending, stretch forming, deep drawing. Types of dies used in press working, defects in formed part and remedial measures, sheet metal formability, formability limit diagram. High velocity forming: Comparison with conventional forming. Explosive forming, Electro hydraulic, Electro Magnetic forming, Dynapak and Petro-forge forming.
Course outcomes: The student should be able to
- Understand elements of plastic deformation which is required as a pre-requisite for studying fracture mechanics course
- Design press tools which are essential for hot and cold working
- Understand and can establish its superior material properties of deformed components produced )
(Assessment: The student should be evaluated based on the assignments and objective tests. The student’s learning abilities should be tested periodically in classes. Unit tests are to be conducted at the end of each unit).
