摘要
为了研究切削参数对高速铣削SiCp/Al复合材料表面微观形貌的影响,本文采用不同切削参数进行了高速铣削实验,利用Talyscan150型表面粗糙度测试仪对加工表面进行测量,对获得的表面数据进行功率谱密度(PSD)分析。结果表明:高速铣削SiC颗粒增强铝基复合材料时,进给量与铣削深度对功率谱密度影响不大,切削速度是主要影响因素,并且随着切削速度的增大,功率谱密度值降低,表面质量提高。加工表面的主要空间波长成分能够反映加工工艺条件对加工表面形貌的影响。
For the purpose of investigating the effect of cutting parameters on surface micro-topography in high speed milling of SiCp/Al metal matrix composites,the high speed milling experiments were performed.The machined surface was measured by the Talyscan150 surface roughness tester.The acquired surface data was analyzed using the method of power spectrum.The results showed that both feed rate and depth of cut have a little effect on the value of power spectrum.and cutting speed is the main affecting factor.The magnitude of main spatial wavelength on the machined surface can reflect the effect of cutting parameters on surface micro-topography.
