Abstract
Regarding the issue of low surface quality in the traditional machining of SiCp/Al composite materials, it proposes a amalgamation of laser preheating and ultrasonic elliptical vibration turning technology. However, the strong fluctuation and high temperature during the processing directly affect the surface quality. Therefore, to enhance the regulation of the cutting temperature, this paper establishes a cutting temperature prediction model that takes into account the repercussions of material heterogeneity, laser thermal action, and ultrasonic elliptical tremor. The analysis of the cutting temperature distribution was conducted through the application of the predictive model, and the verification was carried out by means of the finite-element model. Ultimately, the cutting temperature was confirmed by means of experimental verification. Meanwhile, the influence of temperature on the surface microstructure was investigated. The results demonstrate that the highest temperature distribution within the cutting layer is observed at the point of contact between the tooltip and the vicinity of the chip. The greatest discrepancy between the theoretical temperature and experimentally determined data is 17.1%. The application of a laser heat source results in an increase in cutting temperature. Furthermore, choosing the appropriate amplitude can effectively reduce the temperature and processing damage.
