Abstract: In our previous work, an elliptical ultrasonic assisted grinding (EUAG) method was proposed and the experimental works including the establishment of experimental apparatus and the preliminary experimental results were published earlier in this journal. In this paper, further results on experimental investigations of EUAG of monocrystal sapphire were presented; a series of grinding experiments are carried out to reveal the effects of the process parameters on the surface roughness; by examining the wheel surface conditions and the surface roughness, the influence of wheel wear mode on the surface roughness during the grinding process is also clarified.

Keywords: abrasive technology; elliptical ultrasonic assisted grinding; EUAG; monocrystal sapphire; surface roughness; wheel wear; surface quality; process parameters; wheel surface; grinding wheels.
