| 摘 要： | 文摘SiC_p/Al复合材料在切削加工中存在严重的表面质量问题。本文设计单因素试验,采用硬质合金涂层刀具对SiC_p/Al复合材料进行铣削加工,研究了加工参数对表面粗糙度的影响。结果表明:表面粗糙度随切削速度的增大先增大后减小,随进给量、径向切深、轴向切深的增大而增大;使用较大的切削速度、较小的进给量和不大于4 mm的径向切深能获得较好的加工表面质量。

| Abstract: | There are serious problems in surface quality of the mided SiCp/Al composites. The milling tests on SiCp/Al composites were conducted with cemented carbide coating tools. Through single factor experiment, the article investigated the influence of cutting parameters on surface roughness.The results suggest that the surface roughness increases at first, then decreases with the increase of cutting speed, and increases with the increase of feed, radial cutting depth and axial cutting depth. The machined surface quality could be improved by using high cutting speed, low feed and the radial cutting depth equal or less than 4mm. |
