Study on Surface Roughness in Ultrasonic High-Speed Milling of SiCp/Al Composites

The orthogonal analysis and single factor analysis were used to analyze the roughness of SiCp/Al metal matrix composites (SiCp/Al MMCs) with ultrasonic high-speed milling and high-speed milling. The influences of milling speed, feed and milling depth on the roughness were studied. The research indicates that the roughness in ultrasonic high-speed milling is lower than that in high-speed milling under the same condition, at the same time the optimal parameters of ultrasonic high-speed milling are obtained, this has a guiding significance for finish machining of SiCp/Al composites.
