Abstract

In this paper, a transient dynamic finite-element analysis was carried out to investigate the effects of the cutting speed on cutting force, cutting temperature, and the chip-shear angle. The workpiece material is SiCp/Al composites with lager particle and high volume fraction. The results show that the cutting force decreased, while the cutting temperature and chip-shear angle increased evidently with increasing of cutting speed. The results obtained from this study can predict the behaviors of machining SiCp/Al composites very well and the variation trend is agree well with that of the experiments.
