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。

Electrical gear--ratio has realized the match of position and speed between aimed out- line and practical outline. However, match of interplotion accleration and AC servo system's maxi- mim 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.
