Abstract

Abstract:

Electrical gear-ratio has realized the match of position and speed between aimed outline and practical outline. However, match of interplotion accleration and AC servo system's maximim accleration was ignored. When electrical gear-ratio was deviated subtantially from 1, contour error and cutting efficiency for CNC machining will be affected unfavorably. According to the change of feed-shaft inerita, contour precision requirment, transmiting mechanism and so on, this paper proposed a novel optimal algorithm on electrical gear-ratio and interpolatting accleration to decrease the effect from electrical gear-ratio. Experimental results prove that the algorithm is feasible.

Key words: CNC machine, contour error, cutting efficiency, electrical gear-ratio

摘要：

电子齿轮比仅考虑了在尺寸、加工速度上实现目标值与实际值的匹配，而忽视了插补加速度与交流伺服系统实际最大加速度能力的匹配。当电子齿轮比调节为偏离1较多的数值时，会对数控机床的轮廓误差和加工效率产生较大的不利影响，提出电子齿轮比和插补加速度优化算法，以减小电子齿轮比对数控机床轮廓误差和加工效率的影响。实验结果证明该算法是可行的。
