Effects of high-speed milling parameters on surface integrity of TC4 titanium alloy

In order to provide relatively systematic experimental basis for optimizing the high-speed milling parameters o Chinese TC4 titanium alloy, the effects of high-speed milling parameters on surface integrity of TC4 titanium alloy processed with cemented carbide cutter were investigated. Section 1 of the full paper selects the lowest of three levels of evaluation criteria of surface integrity from Ref.8, which is the translation of a U.S. technical manual. Section 2 explains our surface integrity experiments of high-speed milling of TC4 titanium alloy. Section 3 presents the experimental results and our analysis. Table 4 and Figs.4 and 5 in subsection 3.1 give the experimental results on surface roughness and morphology. Figs.6, 7 and 8 in subsection 3.2 present the experimental results on microhardness. Figs.9 and 10 in subsection 3.3 show the experimental results on microstructure. Based on our analysis of the experimental results in section 3, section 4 gives four preliminary conclusions.
