摘　　要：磨削加工是弧面凸轮加工的一个重要工序,弧面凸轮的加工质量和精度与其密切相关。通过采用行星式磨削方法和单侧面磨削原理,在行星式磨削装置中增加微进给机构,通过监测装置所反馈的数据,使得砂轮在磨削过程中可以通过微进给机构增大砂轮的公转半径,实现砂轮的磨损补偿。弥补了行星式磨削方法不能在磨削时进行磨损补偿的缺点,从而能够实现弧面凸轮的连续磨削,提高了弧面凸轮的磨削效率和磨削精度。Grinding is an important process in machining of globoid indexing cam. It is closely related to the cam processing of quality and precision. By using the grinding method of planetary and one-side grinding principle, the micro feed structure was put in the planetary grinding device. With the monitoring device by the feedback data, it made the grinding wheel radius increase in the grinding process by micro-feeding structure and realized wear compensation of wheel. At the same time, it also overcame the disadvantage that it couldn＇t achieve wear compensation during grinding, which could realize continuous grinding of globoid indexing cam, and improve grinding efficiency and accuracy of globoidal cam.
