摘　　要：利用凸轮机构的分析理论，获得了加工DD680系列汽车制动凸轮的轮廓曲线方程和加工该靠模凸轮的刀具中心轨迹方程。利用微型计算机进行了靠模凸轮轮廓曲线的辅助设计，保证了所设计的靠模凸轮的各项精度。采用该方法计算加工靠模凸轮比用作图法精度高、速度快。The profile equation of brake cam of DD680 series motor vehicles and tool path e-quation for processing copying cam have been obtained by using analytical theory of cam mecha-nism. Computer aided design for copying cam contour has been carried out by means of microcom-puter which ensures precision of the copying cam designed. Higher precision and quicker speed areachieved by the method to calculate and process the copying cam than by drawing method.
