Abstract: The method based on variable angle of ultrasonic vibration assisted grinding was put forward to identify the relationship between direction of ultrasonic vibration and grinding force. The trajectory of grit in contact zone was analyzed. The stress field of contact zone and the grinding force, which were based on the different directions of ultrasonic vibration, were simulated and analyzed by Deform-3D. A series of grinding experiments of GCr15 were conducted. It demonstrates that with the angle α increasing, the grinding force firstly decreased and then increased. The experiment results showed that the error of normal force is 5.23% and the error of tangential force is 8.12%. The model has a higher accuracy.

Key words: ultrasonic vibration assisted grinding, direction of ultrasonic vibration, simulation, grinding force
