| 摘 要： | 使用硬质合金球头铣刀对铝合金叶轮叶片进行了高速铣削试验。研究了切削速度和进给量对加工表面粗糙度的影响。试验结果表明:在高速加工中,每齿进给量比铣削行距对加工表面质量的影响更大;提高切削速度和减少每齿进给量有利于降低加工表面粗糙度。但当切削速度超过某一范围后,进一步提高速度对降低表面粗糙度的作用并不明显;每齿进给量减小到一定范围后,表面粗糙度反而会有所增加;对于铝合金叶片曲面的加工,合理选择切削速度、进给量和行距可获得较低的表面粗糙度值和较高的加工效率。

| Abstract: | A HSM test for aluminum alloy impeller's blade with carbide ball-end cutter was carried out.The influence of cutting speed and feed rate on the surface roughness of machined blade was investigated.The experiment results show that the influence of feed per tooth on surface quality is larger than that of path-interval in the high-speed machining;the high quality surface can be obtained easily by increasing the cutting speed and decreasing the feed engagement;but once the cutting speed excess a critical range,the decrease of surface roughness as increasing of cutting speed was not obvious;while the feed engagement decreased to a very small value,the roughness increased a little.It is expected that the lower surface roughness and higher machining efficiency can be obtained by selecting the appropriate cutting speed and feed rate in HSM for aluminum alloy blades. |
