On-machine monitoring of the wheel-working surface condition with the relative frequency distribution of its profile

In this paper, the possibility of on-machine monitoring of the dulling and loading of the working surface of the grinding wheel is considered based on the relative frequency distribution of its profile measured by the laser m icrometer. The following results are obtained: 1) With the progress of the dulling, the spiky pattern occurs on the relative frequency distribution. 2 ) With the progress of the loading, the shift of the relative frequency dis tribution to the plus side and the swelling up at the plus area of the dist ribution occur. 3) The shift corresponds to the deposition type loading, an d the swelling-up corresponds to the welding type loading. 4) The progress of the dulling and two types of the loading are possible to be monitored us ing the spiky pattern, the shift and the swelling up of the relative freque ncy distribution.
