非规则成形件的毛坯形状与尺寸的确定，一般都是通过成形模并采取试错的方法来完成的。然而，试错要考虑多种因素，又由于落料模必须要在由试错来确定最后的形状与尺寸后才能设计制造，如此就要影响板料零件的生产周期和成本。汽车制动阀安装板是一个比较典型的非规则成形件，在要求极短的周期内同时完成其落料模与成形模的设计制造，用初始网格法来确定汽车制动阀安装板的毛坯形状与尺寸，可在较短时间内完成模具生产工作。

We generally use trial and error method in forming die to determine shape and size of initial blank for non‐regular forming part . However , when using this method , we must consider various factors .For blanking die can be designed and made after obtaining shape and size of blank ,production cycle and cost of sheet metal parts is affected .Since fixing plate of truck brake valve is a typical non‐regular forming workpiece ,blanking die and forming die must be finished in a very short period .For this purpose ,determining shape and size of initial blank for fixing plate of truck brake valve is presented by grid method , so that blanking die and forming die can be finished in a very short period .
