Applications of digital tryout to stampings of hard-to-form parts

摘要: A tryout process is a series of procedures to obtain robust stamping by trial before transferring press shop. During the tryout, control drawbead, determination blank shape, modification binder surface, and so on are carried out mainly using trial-and-error approach. As level difficulty increases, formability involved in becomes sensitive contour deformed or shape. In order solve problems parts that very difficult form, digital simulates real conjunction with beadless demonstrated. Furthermore, possibility practical applications investigated showing solution procedure for proposed tryout. Since desktop rather than shop, precise can be realized if optimal design technique used dete...
