| 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.

| Abstract: | 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. |
