Abstract：
|
|
A method of blank design based on forward and backward simulation for designing the blank was researched.The main process steps were as follows: first,the capability parameter of the material was measured;and then initial blank was got from backward simulation;at last,the blank was modified by using forward simulation.The results show that this method has settled the low precision problem in experiential method and backward simulation.Using the accurate blank from optimize design,non-trimming products can be obtained,which has great economic benefits.
