In the grinding process, the friction energy generated by grains and the workpiece in the grinding zone will affect the service life of the grinding wheel. Ultrasonic-vibration-assisted grinding (UVAG) can reduce the friction force and reduce the generation of friction energy during grinding. In this work, the wear mechanism of grinding wheels in UVAG is discussed in detail from the perspective of the grain grinding trajectory and tribology. The results show that UVAG has a smaller friction force than conventional grinding (CG). Furthermore, when the initial included angles of grains are 90 degrees and 150 degrees, the friction energy of a single grinding surface in UVAG is reduced by 24% and 37% compared with that of CG, respectively. In UVAG, the grains are prone to microfractures, and the self-sharpening ability of the grinding wheel is enhanced, which can obtain a lower grinding force and better grinding surface quality.
