摘　　要：对刀是非圆齿轮滚齿加工时的关键工序。传统对刀方法依靠人工利用对刀规对刀,费时费力。在分析传统人工对刀的基础上,提出了一种新的自动对刀方法。该方法在滚刀轴和工件轴上各加装一光电编码器,通过合理设置滚刀轴与工件轴的机械零位与各自轴上的光电编码器零位重合,可实现自动重复对刀,从而显著提高对刀精度和效率。Tool adjustment is the key processes of Non-circular gear hobbing.Traditional method which manually used tool gage is Time-consuming and laborious.Based on analysing traditional method,a new method of automatic tool adjustment is Proposed.By installing two photoelectric encoders on the hob axis and workpiece axis,and reasonably setting the zero position signals of photoelectric encoders coincident with each mechanical zero of two axis.By this method,tool adjustment Can be automatic and repeated,and thus the accuracy and efficiency is significantly improved.
