According to dimensions

cutter parameters and machining parameters of spiral bevel gears

spiral bevel gear machining 3-D models are established.Several key finite element analysis techniques of metal cutting processes

such as the separation criteria

the definition for interaction of cutter and chip

the friction mode

are studied.The finite element models of spiral bevel gears are established

and milling process of a tooth surface is simulated in different parameters.In addition

the shape and the stress of the cutting layer for results of simulation are analyzed.The results show that: the rake angle and cutting layer deformation increase

the main cutting force decreases;the cutting speed increases

the main cutting force decreases;the rake angle should be 20°

the cutting speed should be the faster one which is based on actual situation.It could be used to select and study the process parameters of spiral bevel gear milling process.
