摘要

: High speed machining technology is being widely used in the manufacturing of molds and dies by virtue of high productivity and high surface finish quality. This paper aims at revealing the feasibility of high speed hard milling of D2 steel experimentally. Average surface roughness, residual stress and micro-hardness are used as the evaluation criteria. Firstly, the average surface roughness in the feed direction is generally smaller than that in the step-over direction. Moreover, a high spindle speed contributes to obtaining a small average surface roughness. Secondly, the surface residual stress induced by the hard milling process tends to presenting in compression state and decreasing with the increase of spindle speed. At last, an obvious increase of hardness can be seen on the machined surface because the hard milling process will produce more severe plastic deformation compared to the traditional milling of annealed AISI D2 steel. This study is useful for the popularization of high speed hard milling technology in actual production.
