Abstract: Aiming at the problems of large tool loss and serious chipping in the traditional ceramic tile edge grinding, and the secondary damage to the machined surface caused by the end face of the grinding disc parallelled with the workpiece, a rotary ultrasonic edging method for grinding the end face of the disc and the workpiece at a certain grinding angle was proposed. The singlefactor experimental study on the variation of the grinding force of the ceramic tile and the grinding disc at different grinding angles and grinding heights was carried out by using the rotating ultrasonic edging tester and Kistler dynamometer. The influence of the grinding angle, grinding height and other test variables on the grinding force were investigated by orthogonal test. The results indicate that the grinding angle has little effect on the grinding force, and the grinding height has the most obvious influence on the radial grinding force. The order of influence of each factor on the grinding force from big to small are the feed rate, the grinding depth, the grinding height, the spindle speed, the ultrasonic current and the grinding angle.
