高速铣削参数对铝合金零件表面粗糙度的影响

高速切削技术可以降低生产成本,提高零件的表面质量。笔者采用正交实验方法,研究硬质合金刀具高速铣削铝合金材料时,每齿进给量、切削深度、切削速度和行距等铣削参数对零件表面粗糙度的影响。通过对实验数据的直观分析和方差分析,得出了影响零件表面粗糙度大小的主次因素,并确定出较优的铣削参数。结果表明：每齿进给量、切削深度、切削速度和行距分别在0.06 mm/齿、0.6 mm、942.48 m/min和0.05 mm附近取值时,可获得较好的表面质量。该研究为指导企业生产实践提供了的参考依据。

Influence of high-speed milling parameters on aluminum alloy work-piece surface roughness

High-speed cutting could reduce production costs and improve the surface quality of work-piece.This paper introduces the use of orthogonal test to probe into the effect on the surface roughness by milling parameters,such as feed-rate/tooth,cutting depth,cutting speed and moving-distance as in the case of cemented carbide cutter cutting aluminum alloy at high speed.The paper gives the relation of major factors affecting surface roughness from the experimental datum of direct analysis and variance analysis,and the best milling parameters.The results show that the better surface quality can be obtained if feed-rate/tooth,cutting depth,cutting speed and moving-distance take values close to 0.06 mm/tooth,0.6 mm,942.48 m/min and 0.05 mm respectively.The study provides experimental bases for enterprises.
