This paper proposes a novel polishing method called submerged air jet polishing (SAJP). The microscopic theoretical model of SAJP is established based on the micro-cutting model of the single abrasive particle. The erosion removal mechanism of SAJP processing titanium alloy and the material removal mechanism under different process parameters are studied from a microscopic perspective.
In this paper, a novel polishing method, submerged air jet polishing (SAJP), is proposed. In this method, the nozzle and workpiece are completely immersed in the abrasive fluid. When the compressed air is sprayed from the nozzle in the abrasive fluid at high velocity onto the workpiece surface, the material removal occurs on the workpiece surface due to abrasive contact and cavitation. The main finding of this paper is to establish the microscopic theoretical model of SAJP on the basis of the micro-cutting model of the single abrasive particle. The erosion removal mechanism of SAJP processing titanium alloy was studied by simulation combined with experiments, and the material removal mechanism under different process parameters was explored from the perspective of microscopic evolution.
