| Abstract: | Characteristics of laser power spectrum about grinding wheel topography and its collecting principles are expounded, and its detecting device is designed. Experimental results show that the measured characteristic parameter curvcs about the grinding wheel topography are identical with the grinding basic theories and that the feasibility of measurement on grinding wheel topography by a laser power spectrum is proved. |
