Ultrasonic assisted grinding process with minimum

2016-8-15  Optimization of grinding process from the viewpoint of surface integrity and production cost is of the primary interest in grinding technology. Previous studies have shown that ultrasonic vibration assisted grinding (UAG) improves the grinding performance. These improvements are attributed to the change of the nature of the cutting process in UAG.
