Abstract
There are many discrepancies in opinions hitherto about the probability density function of cutting edges after dressing treatment. The present paper deals with the effect of the dressing treatment on the grinding wheel and ground surface. The theoretical explanation was offered for the distribution curve of cutting edges after dressing and the root mean square roughness of ground surface. The calculated values based on the theoretical explanation show good agreement with experimental values. The theory shows that when the grinding wheel is dressed by the diamond dresser with a conical apex, the distribution curve of cutting edges changes from the rectangular distribution to the parabolic one with the increase of the dressing number and the root mean square of surface ground with it can be calculated theoretically.
