February 13, 2007

By:

Setting the processing variables is different between the net shape and non-net shape processes. While non-net shape variables have to be programmed constantly to change the tool's position in space to follow the unique shape of the part being made, the shape of the part for the draw forming net shape process is built into the die.

Solving punch breakage problems - Part II

January 9, 2007

By:

Cutting shear, or the angle ground into the end of a punch, has a big effect on punch deflection and breakage, as well as press tonnage required. Retainers, which hold the punch to the die shoe, also are important. The backing plates, ball lock punch retainers, and headed styles of punches and retainers all require careful consideration.
