Abstract
Compound milling was generally composed of multiple rotational motions and multiple translation motions. The compound milling path equation and the compound milling paths were obtained by homogeneous transformation matrix method. The effects of compound milling path on surface quality were researched. The results show that the surface roughness of enveloping surface of compound milling was obviously lower than that of unenveloping surface. The surface roughness of unenveloping surface of compound milling was similar to that of ordinary face mill. The feed has little effects on the surface roughness of unenveloping surface, but the surface roughness of enveloping surface increases with the increase of feed. The surface roughness Ra of the unenveloping surface and the enveloping surface decrease with the increase of cutting rate ratio k. The residual stress of compound milling is smaller than that of ordinary face mill, and the residual stress of enveloping surface in compound milling is smaller than that of unenveloping surface.
