2.5D C/SiC复合材料铣削材料去除的实验研究
Experimental Study on Material Removal in Milling of 2.5D C/SiC Composites
摘要
Abstract
To explore the material removal characteristics of 2.5D C/SiC composite miling,end mills and fish-scale mills were used to perform conventional milling(CM)and ultrasonic vibration-assisted milling(UAM)on 2.5D C/SiC composites.The changing laws of cutting force and cutting temperature under four milling conditions were analyzed,and the removal characteristics of 0°,90° and z-direction needle punched fibers were studied.The results show that,compared with traditional end mill and CM,fish-scale mills and UAM can significantly reduce cutting force and cutting temperature,respectively.UAM can change the overall removal of fibers into broken removal and reduce surface defects.The combined process of fish-scale mills and UAM can greatly reduce surface defects,cutting force and cutting temperature,improve the surface quality of the workpiece,and provide feasibility for low-damage milling of 2.5D C/SiC composites.关键词
