Basic Formability
3-Day Course
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 binder & blankholder capabilities are thoroughly discussed. It teaches the fundamentals of analyzing a part by understanding its markings and how to evaluate its severity.
WHO SHOULD ATTEND:
Tooling Supervisors, Product, Process, Manufacturing and Tooling Engineers, and Tool and Die Makers.
