Prediction of cutting force of particle-reinforced polymer matrix composites

Abstract

Abstract In this paper, the orthogonal cutting experiment and simulation analysis of Cu/PTFE composite materials are carried out with cemented carbide tools. The equivalent homogeneous model is adopted to realize the three-dimensional cutting simulation process. Compared with the experimental results, the predicted cutting force is in good agreement with that of the experimental results, and the deviation does not exceed 20%. The relationship between processing parameters and surface roughness under different cutting conditions is discussed in detail. The results show that the feed rate has a significant effect on the surface roughness, and the feed rate should be controlled during the machining process to obtain high surface quality. Through the observation of the turning surface, there are phenomena such as particle pulled off, cut off, and pressed in the processed surface morphology.
