摘要

根据不同种类齿轮轮廓展成加工成型的运动规律以及齿轮展成加工误差形成的规律,优化了数控系统的运动控制结构。运用"电子复合差动",结合来自滚刀主轴的角位置检测编码脉冲和来自与工件主轴转动相关的运动坐标位置或角位置检测编码脉冲,通过位置控制和误差补偿单元的控制,实现了机床范成分齿运动误差、齿向误差、刀具磨损等的在线实时补偿,并拓展了非圆齿轮、轴向修形齿轮（如小锥度、鼓形）等的滚切加工功能。

Abstract

According to the principles of various gear profile generation and gear generating error,the motion control structure of NC hobbing system for gear machining is optimized. The electronic composite differential unit is used to process the angle position pulse from the hobbing spindle and to process the motion coordinate（ or angle position） pulse from the workpiece axis. By means of position control and error compensation control unit,the on- line real time compensation of errors as tooh pitch division error,longitudinal tooth error,and tool wear error is realized. Meanwhile,the hobbing function of non- circular gear and axial modification gear（ small taper or drum type） is also expended.
