Abstract: In this paper, grinding wheel wear is measured by laser power spectrum. By analyzing the real power spectrum of grinding wheel wear with "experiment and statistics method", the detecting princple of laser power spectrum is proved, and its half with ξ0 is determined by the spectrum center to the position in which the intensity drops to 4% its maximum intensity. In addition, the grinding wheel parameters with the aluminum disk wheel are calibrated. Finally, the detecting experiments on the worn grains distribution are carried out, and grinding mechanism is identified.

Key words: grinding wheel, wear, laser application
