Article Preview

The paper is concerned with the effect of cutting parameters on surface microhardness in the high speed milling of titanium alloy TC17 with carbide cutting tools by single factor experiment. To provide experimental evidence for process parameter optimization and surface quality control in high-speed cutting titanium alloy parts. The results show that to aim for lower hardening layer depth, cutting parameters can be optimized as: vc=391.7m/min, fz=0.05mm/z, ap=0.45mm. The effect of cutting parameters on microhardness has experienced surface hardening-softening - re-strengthening - the process of stabilizing,in the experimental range.
