摘　　要：选择利用自由曲面的数字化加工方法对螺旋锥齿轮齿面进行数字化精加工路径规划,选用指状铣刀,采用粗加工、半精加工而后精加工的加工策略,以刀具接触点(CC)路径截面法为基础,通过具体分析计算得出合理加工路径,确定出刀具相对工件的位置和姿态.解决了指状刀具和刀轴的干扰问题,并通过计算机仿真和实际操作加工证明此方法的可行性,对改进螺旋锥齿轮的加工制造有一定现实意义.In this paper, the digital machining method of the free-form surface is chosen to do the tool track planning for the spiral bevel＇s digital finishing. We use the finger millingcutter, and choose processes as roughing, semi-finishing and finishing. Based on the CC path cross-section. Through the concrete analysis, we got the reasonable processing route, the position of the tool relative to work piece as well as tool pose. We have solved the interference problem between finger tool and arbor, and demonstrate the feasi- bility of this method through computer simulation and actual operation process. It can help to improve the spiral bevel gear＇s manufacturing.
