摘　　要：面齿轮具有承载能力大、结构紧凑的特点,常用在直升机螺旋翼等航空航天设备中。由于航空条件下对齿面硬度及齿面精度的高要求,通常采用插齿、滚齿或者磨齿等加工方法对齿面进行加工。针对民用齿面材料硬度较低的特性,提出基于立铣刀侧刃五轴铣削面齿轮的加工方法,该方法根据面齿轮齿面几何特征,沿齿廓方向规划铣刀走刀路径,并利用牧野V33-5XB五轴机床结构设计后处理系统,制定面齿轮齿面五轴侧刃铣削程序;开发了干涉判断算法,计算五轴侧刃铣削过程的干涉情况,去除加工轨迹干涉点。测量结果表明,采用本文提出的五轴侧刃铣削面齿轮加工算法加工的面齿轮表面质量优于UG CAM方法。Face gear has the characteristics of large bearing capacity and compact structure.It is often used in military aerospace equipment such as helicopter helical wing.Due to the high requirements of tooth surface hardness and tooth surface accuracy under aviation conditions, gear shaping, gear hobbing or gear grinding are usually used to process the tooth surface.Aiming at the gear material with low hardness of civil tooth surface, a machining method of face gear based on the side edge of end mill is proposed.According to the geometric characteristics of face gear tooth surface, the method plans the cutter path along the tooth profile direction, designs the post-processing system and formulate the five axis side edge milling program of face gear tooth surface by using the structure of Makino V33-5 XB five axis machine tool.The interference judgment algorithm is developed to calculate the interference in the five axis side edge milling process and remove the interference points of the machining path.The measurement results show that the surface quality of face gear machined by the five axis side edge milling face gear machining algorithm proposed in this paper is better than that machined by UG cam method.
