A die should be designed to minimize any strip distortion which would tend to change the distance between pilot holes (alter the progression).
模具计划应包管起码的任何变化料带步距的料带扭曲。

The effect of profiled aluminum quality on different design methods have been studied according to the design of profiled aluminum die diffluence hole, lead flow strip working belt and wayout belt.
The mathematics model of multiobjective optimum combination, good algorithms and CAD system for strip layout of multistep progressive die are given in this paper.
