Experimental study on high speed milling titanium alloy in stretches

Through the milling experiment under the stretches condition to titanium alloy TC4(Ti6Al4V),it has focused on studying influence of the high speed milling to the titanium alloy TC4 surface residual stress and the surface roughness,The experimental data of the titanium alloy TC4 surface residual stress and the surface roughness is obtained under the different cutting parameter.The experimental result indicated that the stretch fixation basically does not affect the surface roughness,but residual stress of the processing surface can greatly be improved and residual stress layer thickness is increased.This provides a basis to carry out high-speed tensile milling titanium alloy.
