在介绍双圆弧法计算原理基础上，采用连续双圆弧法插补方式，通过控制插补误差实现加工步长的动态伸缩，获得满足数控机床圆弧插补的轮廓节点数据;开发了相应的数控程序生成软件;只需输入摆线针轮的几个参数，即可获得摆线行星轮的数控加工程序，实现了任意齿数摆线轮数控自动编程;根据轮廓节点数据以及刀具中心轨迹坐标，可对摆线轮的加工过程进行运动仿真。摆线轮数控磨削的实验结果验证了理论推导的正确性和软件的实用性。

Based on the principle of doublearc method, continuous twoway circular interpolation method and the control of interpolation error are used to achieve a dynamic expansion on the process step and to get contours node data that meets the requirements of CNC machine tools’ circular interpolation. Accordingly, corresponding CNC program software can be developed. Using this kind of software, the CNC process program can be gotten but only inputting several parameters of the cycloidalpin gear. In this case, automatic programming for cycloid gear of any number of teeth is realized. According to the contours node data and the track coordination of tool center, the process program of cycloid gear can be simulated. The experimental result of cycloidalpin gear CNC grinding validates the correctness of the theory deduction and practicality of the software.
