中文摘要:
      目的 研究金刚石涂层立铣刀和 PCD 立铣刀切削铝合金时,铝合金表面粗糙度以及刀具的使用寿命。 方法 通过实验比较 1 μm、 5 μm 金刚石涂层四刃立铣刀和 PCD 立铣刀在高速干式切削条件下切削铝合金的性能,并通过走刀距离比较不同状态刀具的使用寿命以及在走刀过程中的粘刀情况,用表面粗糙度测量仪测量加工的铝合金表面粗糙度。 结果 1 μm、 5 μm 金刚石涂层立铣刀加工铝合金失效距离分别为 25 m、 75 m, PCD 立铣刀加工铝合金 96 m 后失效; 1 μm、 5 μm 金刚石涂层立铣刀切削铝合金表面粗糙度平均值分别为 1.07 μm、1.10 μm, PCD 立铣刀切削铝合金表面粗糙度平均值为 0.80μm。结论 5 μm 金刚石涂层立铣刀是 1 μm 金刚石涂层立铣刀寿命的 5 倍, PCD 立铣刀使用寿命最长;1 μm、 5 μm 金刚石涂层立铣刀切削铝合金表面较 PCD 立铣刀粗糙,在相同切削环境下切削铝合金时,PCD 立铣刀使用寿命较金刚石涂层立铣刀提高,且在抑制粘刀方面效果十分明显。
英文摘要:
      Objective To research the performance of coating end mill and PCD end mill on cutting aluminum ally. Methods In this paper, four-flute end mill with 1 μm diamond coating, four-flute end mill with 5 μm diamond coating and PCD end mill were taken as the objects to study the tool life and chip sticking situation, the feeding length of cutting aluminum alloy in the process of high-speed dry cutting of which was compared in the experiment, furthermore, the surface roughness of aluminum alloy was tested with the surface roughness tester. Results The results showed that the failure distance of end mill with 1 μm diamond coating or 5 μm diamond coating was 25 meter or 75 meter and that of PCD end mill was 96 meter when cutting aluminum alloy. The average surface roughness of end mill with 1 μm diamond coating or 5 μm diamond coating was 1.07 μm or 1.10 μm and that of PCD end mill was 0.80 μm. Conclusion The life of the end mill with 5 μm diamond coating was four times more than that of the end mill with 1 μm diamond coating, while the PCD end mill has the longest service life. The roughness of end mill with 1 μm diamond coating or 5 μm diamond coating was higher than that of PCD end mill when cutting aluminum alloy. PCD end mill had longer life than diamond coating end mill and could also significantly reduce the sticking situation when cutting aluminum alloy in the same cutting environment.
