The effects of cutting process parameters of YG8 and TiAlN coated cemented carbide tools on the surface roughness and surface hardness of TC4-DT titanium alloy were studied by single factor turning,low speed milling and orthogonal high speed milling experiments.The ex-perimental results show that the surface roughness of titanium alloy changes with the three ele-ments of cutting.The higher the cutting speed,the lower the roughness.The larger the feed,the greater the roughness;however,it fluctuates with the cutting depth.The average surface rough-ness obtained by using TiAIN coated cemented carbide end mill is smaller than that of YG8 ce-mented carbide end mill,and the hardness of the machined surface changes less,which is more suitable for milling TC4-DT titanium alloy.
