首发时间:2011-09-02
摘要:结合正交分析和单因素分析对高体分SiCp/MMCs在超声高速和高速铣削两种实验条件下的粗糙度进行分析,研究铣削速度、进给量和切削深度对粗糙度的影响程度,及三种切削用量分别对粗糙度的影响规律。研究表明超声高速铣削在同等铣削条件下的粗糙度值比高速铣削的粗糙度值低,并得到了超声铣削加工时的最佳铣削参数,这对SiCp/Al MMCs的精加工具有指导性意义。

Study on surface roughness of high volume SiCp/Al MMCs with ultrasonic high-speed milling and high-speed milling
Abstract:The orthogonal analysis and single factor analysis were used to analyze the roughness of high volume SiCp/Al MMCs with ultrasonic high-speed milling and high-speed milling. The influence degree and law of milling speed, feed and milling depth on the roughness were studied. The research indicates that the roughness of ultrasonic high-speed milling is lower than high-speed milling at the same condition, at the same time the optimal parameters of ultrasonic high-speed milling was obtained. It has guiding significance for finish machining of SiCp/Al MMCs.
Keywords: Orthogonal analysis SiCp/Al MMCs Ultrasonic high-speed milling PCD tool Surface roughness
