Abstract The processed surface contour shape is extracted with the finite element simulation software, and the difference value of contour shape change is used as the parameters of balancing surface roughness to construct the infinitesimal element cutting finite element model of supersonic vibration milling in cutting stability domain. The surface roughness trial scheme is designed in the central composite test design method to analyze the surface roughness test result in the response surface methodology. The surface roughness prediction model is established and optimized. Finally, the finite element simulation model and surface roughness prediction model are verified and analyzed through experiment. The research results show that, compared with the experiment results, the maximum error of finite element simulation model and surface roughness prediction model is 30.9% and12.3%, respectively. So, the model in this paper is accurate and will provide the theoretical basis for optimization study of auxiliary milling process of supersonic vibration.

Abstract In this paper, the finite element simulation model of diamond tool milling SiCp/Al composites was established.The milling force, stress distribution and removal mechanism of SiC reinforced granular material were studied. The correctness of finite element simulation is verified by micro milling experiments. The results show that the maximum stress mainly occurs when the SiC particles are milled with PCD tool. The removal mechanism of particles is different when the tool is milling particles at different positions. The material surface defects are reduced and the surface quality is improved as the cutting speed is increased. The surface defects of SiCp/Al milling with single edge diamond milling tool mainly include cavities, microcracks, scratches and pits. According to the measurement results, it can be founded that the milling depth has the greatest influence on the surface roughness, followed by the spindle speed and the feed speed.
