3 day course

COURSE OBJECTIVE:

The objective of this course is to understand the inputs into a stamping operation and how to interpret the results. The effects of parameters such as geometry, material properties, press curves, and blankholder capabilities are thoroughly discussed. It teaches the fundamentals of analyzing a part by understanding its markings and how to evaluate its severity.
