Abstract:

Based on the modified-roll method geometry theory and 4-axis
 CNC machine kinematics principles,the instantaneous cutting area formulas of
the spiral bevel pinion rough milling were deduced.According to the traditional milling
force model,the spiral bevel pinion rough milling force model based on the modified-roll
method were presented,the milling force simulation programs were composed and the
experimental schemes were designed.The experimental results show that the amplitude
of the main motor cutting power and the transducer output power are almost in the same
interval and the time intervals are the same.And the rough milling force model herein can guarantee a certain precision.

Key words: spiral bevel gear, modified-roll method, rough milling, milling force model
