弧面凸轮数控加工中心距误差分析方法研究

Discuss on analysis methods for center distance error of globoidal indexing cam in NC manufacturing

弧面凸轮廓面为空间不可展曲面,加工和误差检测难度较大,根据弧面凸轮数控加工专用铣床的加工实践,通过测量所加工弧面凸轮停歇期凸脊宽度误差的方法来调整弧面凸轮中心距,该方法在生产应用中有一定实用价值。

The profile of globoidal indexing cam is special complex surface,so there is no good method to inspect its machining error. Through the process of special CNC milling machine for globoidal indexing cam,measuring the center distance error to adjust globoidal indexing cam center error,this method has practical value in product.
