Formability of Sheet Metal

The objective of this 2-day course is to provide an understanding of the fundamental aspects of sheet metal stamping. It will provide insight into the manufacturing and processing of different grades of stamping quality sheet metal, characterization of sheet metal behavior during stamping and the methods for evaluating forming defects, the basic principles of stamping tool design including the stamping press actions, and the state of the art computer based approach to stamping design and analysis.

Class Format
  • 2 day
  • Instructor led
  • Presentation and hands-on exercises
  • One student to a computer


Suggested Follow-Up
