摘要
基于PMAC-clipper运动控制卡,提出任意二维轨迹的切向跟随插补算法。在xy平面二维坐标系中,实现刀具中心的轨迹运动控制;在旋转轴C坐标系中,根据xy坐标系中刀具的实时位置坐标,计算得到与之相切的切线方向的转角,控制刀刃始终与轨迹相切。此算法简单、高效,可充分利用运动控制卡的功能,适用于数控裁床等特殊数控设备的控制。
A tangent following interpolation algorithm was proposed based on PMAC-clipper motion controller for two-dimensional curve. The center of the tool could move along the curve in the xy coordinate system. In the C coordinate system, the tangential angle was gotten by the real-time coordinates of the tool in the xy coordinate system, and the tool edge direction was controlled to tangent to the curve always. It is a simple, efficient algorithm which can make full use of the function of the PMAC. It is suitable for CNC cut- ting machine and other special NC equipments.
