Experimental Study on Surface Roughness and Surface Micro-morphology of SiCp/Al

In order to study the regulation of the roughness and micro-morphology of the machined surface with cutting parameters changing, a single factor experiment of micro milling groove was carried out on Si Cp/Al using a 2 edges hard alloy end mill with a diameter of 1 mm (4HCE010025S04). The following conclusions are obtained through the experiment and detection analysis: With the spindle speed n increasing, the roughness of the milling groove surface gradually decreases, the quality of the machined surface becomes better, and the contour of the bottom of the groove is flatter; with the feed rate f increasing, the roughness of the milling groove surface gradually increases, the quality of the machined surface gets worse, and the contour of the bottom of the groove is worse; with the cutting depth ap increasing, the roughness of the milling groove surface is reduced and the quality of the machined surface improved, and the contour of the bottom of the groove becomes more flatter, although the depth does not change obviously.
