Abstract

Highly efficient machining of SiCp/Al composites is always a challenge due to their poor surface integrity. This paper aims to study the cutting mechanism considering the interaction between particles and reveals the removal process of SiC particles under different cutting parameters. Furthermore, a thorough analysis was conducted to examine the impact of SiC particles on cutting force, chip shape, and surface defects. The results indicate that the form of particle removal is determined by the relative position of the cutting path and SiC particles, which includes particle fracture, push-in, slip, and debonding. As the cutting depth increases, the cutting force also increases from 10.4 to 20.1 N, and the presence of SiC particles can cause significant fluctuations in the cutting force. In addition, an increase in cutting speed improves surface quality, and the chips primarily exhibit a block- and sheet-like shape. This study provides valuable insights into the removal mechanism and process research of SiCp/Al composites.
