为了实现高效的五轴加工,本文对五轴RTCP技术进行深入研究,通过对旋转角度的细分及插补点处非线性误差补偿,减小了加工中的非线性误差并满足补偿算法的实时性,通过对各轴速度进行约束的前瞻算法、减小了加工过程中的机床振动,从而提高了工件表面的加工质量.本文提出采用基于参数配置的运动学模型,提高了工件程序的可移植性.最后将该算法添加到GJ-310数控系统中,并进行了试验验证,结果表明该算法可以满足加工要求.
In order to achieve efficient five-axis machining, the paper deeply studies the five-axis RTCP technology. By subdividing the rotation angle and compensating the nonlinear errors at the interpolation point, the nonlinear errors in machining are reduced and the real-time compensation algorithm is satisfied By using the forward-looking algorithm which constrains the speed of each axis, the vibration of the machine tool during machining is reduced and the machining quality of the workpiece surface is improved.This paper proposes a kinematic model based on parameter configuration to improve the portability of the workpiece program Finally, the algorithm is added to the GJ-310 numerical control system and tested. The results show that the algorithm can meet the processing requirements.
