Soft abrasive flow polishing based on the cavitation effect

The International Journal of Advanced Manufacturing Technology, 2018
The fluid medium used for soft abrasive flow (SAF) is of low viscosity and high flow velocity. The conventional SAF processing method is widely used due its ability to avoid damage and its adaptability of the workpiece surface. However, the current SAF method also suffers from limitations such as long polishing times and low processing efficiency.
