6、优化;冲压模具37AbstractBlank layout is one of the most important processes in stamping die design. As the major cost in sheet metal stamping is the material cost, any efforts to minimise the scrap may result in substantial savings not only in strip material, but also in overall production. This
7、paper is mainly targeted at establishing a practical blank layout optimisation system for stamping die by using AutoCAD’s ObjectARX toolkit. The basic principles of blank layout optimisation are first described, and then the general structure of the system is
