Abstract
Abstract: High volume fraction SiCp/Al composites were milled in ultrasonic longitudinal high frequency vibration milling and conventional milling in this experiment. Meanwhile, the form of wear and wear mechanism of PCD milling tools were investigated. In addition, the relationship between the maximum wear of PCD milling tool and the length of milling were obtained. The results show that it is mainly flank wear of PCD cutting tool under the same milling parameters, which are caused due to hard points wear and thermal and chemical wear. Furthermore, the wear of PCD cutting tool by the ultrasonic vibration milling is smaller than that obtained by the conventional milling.
