EHTT2022: Multi-physical modeling and adjusting for ultrasonic assisted soft abrasive flow processing

Abstract

The polishing efficiency of the soft abrasive flow (SAF) method is low, which is not in line with the concept of carbon emission reduction in industrial production. To address the above issue, a two-phase fluid multi-physics modeling method for the ultrasonic assisted SAF processing is proposed. The turbulence kinetic energy at different ultrasonic frequencies are studied. Simulation results show that the ultrasonic vibration can induce cavitation effect in the constrained flow channel and promote the turbulence intensity and uniformity of the abrasive flow. A set of comparative polishing experiments with or without ultrasonic vibration are conducted to explore the performance of the proposed method. It can be found that the ultrasonic assisted SAF method can improve the machining efficiency and uniformity, so as to achieve the purpose of carbon emission reduction.
