摘要
以四点接触球轴承沟道轮廓测量为例，对接触测量中测头半径引入的系统误差进行了理论分析，给出修正误差的方法及微机处理数据的程序。
The system error caused by the radius of the probe in the four point touch measurement of the groove profile of ball bearing race is analyzed theoretically. A method for error correction and a data processing program for a microcomputer are presented.
