面齿轮车齿加工中切削角度和切削力计算

Combining a method for skiving cylindrical gear with one for machining face gear is suggested in order to increase the processing effectiveness of face gears. First, the principle of the skiving machining is analyzed, and the machining motion model and the skiving coordinate system are established. The cutting speed of the cutting point on the cutting edge of the skiving tool is derived. Secondly, the rack face and the flank face of the skiving tool are designed, the mathematical model of the cutting angle is established, and the change rule of the cutting angle of the tool during the machining process is analyzed. Finally, using VERICUT and DEFORM simulation analysis software to verify the skiving process, the post-processing errors and the influence of processing parameters on the cutting force are obtained.
