摘要
针对PCD刀具高速铣削体积分数为65%的SiCp/Al复合材料,通过单因素和正交试验研究了不同铣削参数对表面粗糙度的影响。研究结果表明:影响SiCp/Al复合材料已加工表面粗糙度的最重要参数是每齿进给量,其次是铣削深度,铣削速度和铣削宽度对表面粗糙度的影响较小;铣削速度与铣削宽度之间存在一定的交互作用;为得到较好的表面粗糙度,可选择较高的铣削速度、适中的铣削深度和铣削宽度、较低的每齿进给量进行加工。
Regarding high-speed milling 65vol% SiCp/Al aluminum matrix composites by PCD tools, the effects of different milling parameters on the surface roughness were studied by single factor and orthogonal experiments. The results indicate that the influences of the feed rate and cutting depth on surface roughness are more significant than those of the cutting speed and width. And there exist interaction effects between the cutting speed and the cutting width. In order to achieve better surface roughness,it is recommended that a higher cutting speed, a lower feed rate, and a moderate cutting depth and width be chose.
