| Draw Die Development - 1 day
COURSE OBJECTIVE:
Learn the thought process of how to create a draw development. This course provides the basic rules and concepts needed to understand how to design a draw development for quality stampings. Applications for outer and inner panels, and reinforcements are used to illustrate the effects of tip angle, drawbars, overdraw, etc. Students will work in-groups to determine and evaluate draw developments.
WHO SHOULD ATTEND:
Process, Manufacturing, Tooling and Development Engineers and Tool and Die Makers.
