摘　　要：利弧面凸轮分度机构作为自动机械中实现高速、高精度间歇分度运动的新型传动装置,被公认为目前最理想的分度机构,需求量日益增大。但是由于弧面凸轮廓面形状复杂,且为空间不可展曲面,使得其设计与加工比较困难。借助Un igraph ics NX 4.0软件实现了弧面凸轮的参数化设计,简化了设计过程,并提出了一种利用五轴联动加工中心加工弧面凸轮的方法。结合实验室的五轴联动加工中心,对弧面凸轮进行加工试验,验证了加工方法的正确性。Ferguson cam mechanism is a new driving device which is adopted in automatic machine and has high speed and high precision dividing movement.It is recognized to be best dividing mechanism at present and demanded increasingly day by day.However,because of the complicated shape of globoid cam profile and non-developable surface,it is more difficult to design and machine it.With the help of CAD software,the computer is used to design the globoid cam in this paper.Its design process is simplified greatly.At the same time,the method of machining the cam on 5-axies machining center is proposed.Also the machining experiment is done and verifies the correctness of this machining method.
