Abstract：

Through years of design experience and practice, the cause of difficult scrap falling in cold stamping trimming die was analyzed, and the processing difference and the influences of the cutting edge of the cam-trim scrap cutter in different coordinate systems were analyzed. Then, from the view of die structure design and process design, it was summarized various arrangement forms and installation methods of scrap cutter, and the key points of the design in different arrangement forms of the scrap cutter and the specific solution were pointed out. Thus, based on the process design of scrap cutter with open type and linear type die structure design with scrap cutter, corresponding five-axis machining process can solve the problem of scrap falling fundamentally.
