摘要：
Both milling force and temperature are the key influence factor of thin-wall part deformation. Therefore, to study the influence of milling parameters including milling speed, feed per tooth, radial depth of cutting and axial depth of cutting on milling force and temperature in the cutting process,the finite element model of high speed milling thin-wall SDK11 hardened steel part is developed by DEFORM-3D based on the modified J-C material model. The results indicate that milling force increases with an increase of milling speed until milling speed beyond 400m/min began to decline, and milling temperature increases with an increase of cutting speed. Milling force rises with fluctuations with an increase of milling speed, and milling temperature increases with an increase of milling feed, But it appears a decline trend from milling feed of 0.02mm/z to 0.025mm/z. Both milling force and temperature are increasing with the radial and axial depth of cut increasing. but milling force decline and milling temperature increase rapidly from axial depth of 0.7mm to 0.8mm.
