摘　　要：时间分割法的渐开线插补,用若干等弦逼近实际渐开线。通过插补运算,计算出每个插补周期内X、Y轴的进给量以控制相应轴的运动。其运动轨迹合成后形成一段渐开线。该插补流程包括:读取渐开线数据、计算渐开线起点和终点角度,并由此判断和计算渐开线的插补点或终点的进给量并输出,最后进行插补精度分析。For the involute interpolation of time-sharing method, many equivalent chords are adopted to approach the actual involutes. Through interpolation operation, the feed value of X and Y axis in every interpolation period was calculated to control the movement of relative axis. After the cooperation of movement traces, one involute was formed. The interpolation process includes： reading the involute data; calculating the start and end angles of involute; according to the angles, the feed value of involute point or end was judged, calculated and inputted; at last, the involute precision analysis was carried on.
