Tooling Technology
cut lead time and costly mistakes.
“Reducing the need for communication also is key,” Proeber explains. “Today the die designer is dramatically more respon- sible for the die than are the employees machining the components or assem- bling the die. We expect that the design will be 100 percent correct when it reaches assembly. One way we reduce the need for communication— thereby reducing mistakes —is to provide a simple way for the designer to communicate the toler- ance and the machining method of each individ- ual holes in a given plate.
Software flexibility can significantly ease a designer’s challenges. For exam- ple, CimatronE 11 allows users to adapt to a variety of die and forming needs, including the ability to design progressive and transfer dies within the same interface.
knows that a press-fit pin needs x amount of press fit if it is going into a soft plate, and y amount of press fit if it is going into a hardened plate. Die designers can set up the software so that they can select whether that dowel is going into a hard plate or a soft plate—that’s the only interaction required. The software will put the correct hole size in every time.”
A New Communication Protocol
Proeber goes on to describe the second method of communi-
“We do this with two different meth- ods,” Proeber continues.” For years we have been able to easily customize
