| 摘 要： | 在极坐标式CNC磨床上磨削封闭式凸轮轮廓曲线时 ,凸轮的半径变化率和砂轮的大直径成为影响磨削质量的主要因素。为解决砂轮干涉及磨削点处线速度变化影响磨削表面粗糙度的问题 ,提出了极坐标下砂轮磨削点轨迹的等步长插补方法 ,该方法可应用于任何具有C1连续性的正则曲线的CNC磨削

| Abstract: | The radius change rate of cams and the large diameter of grinding wheels are main factors to effect the grinding quality during grinding enclosed profile curves of cams on the polar coordinate CNC grinder.To solve problems of the wheel interference and the linear speed change on grinding points which has an effeet on the grinding surface roughness,a polar coordinate based equal step interpolating method for the grinding point trace is presented.The method can be applied to the CNC grinding of any regular curves with C 1 continuity. |
