摘要
针对数控加工中零部件的切削精度和速率问题,综合速度生成算法和插补算法的优势,设计了一种新的刀具运动轨迹控制算法。利用五次样条和四次多项式微分求导方法,提高刀具运行轨迹精度;结合最优前瞻控制算法,通过选择最优转角速度,弥补了传统S加速曲线存在的缺陷,解决了不同转速间的连接问题,提高了加工效率。通过仿真验证了算法的可行性,为数控技术的智能控制提供了参考。
Aiming at the problems of parts cutting precision and speed,it combines the advantage of speed generation algorithm and interpolation algorithm,puts forward a new kind of tool motion trajectory control algorithm.Using methods of five times spline and four polynomial differential derivative,it improves the precision of the cutting tool path. Combining with the optimal preview control algorithm,it selects the optimal corner speed,makes up the defects of traditional S acceleration curve. This solves the problem of the connection between different rate,improves the processing efficiency. Finally,the simulation verifies the feasibility of the algorithm. The result provides a reference for intelligent control of CNC.
