| 摘 要： | 五轴加工中由于旋转运动的影响,会产生非线性误差.RTCP(绕刀具中心点旋转)功能可使数控系统自动对旋转轴的运动进行实时线性补偿,从而保证插补点始终位于编程轨迹上.在深入分析双转台五坐标机床运动原理的基础上,介绍了一种集成RTCP功能的插补算法,并在MATLAB中做了仿真计算.计算结果表明该算法可以有效减小非线性误差.

| Abstract: | Because of the rotate kinematics, the machining of 5-axis brings up the non-linear error. The RTCP (Rotation Tool Center Point) function can always make the interpolated point on the programming track by a real-time linear compensation of CNC system for motion of the rotary axes. Based on detailed analysis of the kinematics principle of 5-axis machine with dual rotary tables, a new design of interpolated algorithm integrated with RTCP function is presented which is simulated in MATLAB, and the result indicates that the algorithm can reduce the non-linear error effectively. |
