摘　　要：根据对面齿轮高速铣削齿面表面粗糙度的形成机理,分析了面齿轮高速铣削加工中的面齿轮齿面方程,建立了面齿轮高速铣削加工中的铣刀运动轨迹方程。根据高速铣削加工过程中球头铣刀刀刃实际扫成面的交点方程的坐标系,求出高速铣削残留高度。根据球头铣刀受力偏心和弯曲变形,求出面齿轮高速铣削瞬态铣削高度,进而编写M文件计算不同参数变化时对表面粗糙度的影响,通过计算值与实测值的对比,其最大误差在12.8%,结果表明,粗糙度数学模型计算值和实测值基本一致。According to the formation mechanism of the surface roughness of the high-speed milling tooth surface of the face gear, the tooth surface equation of the face gear in the high-speed milling of the face gear is analyzed, and the equation of the trajectory of the milling cutter in the high-speed milling of the face gear is established. According to the coordinate system of the intersection equation of the actual milling surface of the ball-end milling cutter during high-speed milling, the high-speed milling residual height is obtained. According to the eccentricity and bending deformation of the ball-end milling cutter, the high-speed milling transient milling height of the face gear is obtained, and then the influence of the different parameters on the surface roughness is calculated by writing the M file. By comparing the calculated value with the measured value, the maximum is obtained. The error is 12.8%. The calculated roughness values of the mathematical model are basically consistent with the measured ones.
