Abstract
The quantitative method for evaluation of the cutting-edge distribution on a grinding wheel was applied to evaluation of the dressing process with a single-point diamond dresser. The changes in behavior of cutting-edge distribution with dressing by a single-point diamond dresser were clarified. The results of experimental examinations indicated that there is a critical condition of depth of cut for dressing that enables the cutting-edge density to be increased by preventing the release of grains. A decrease in depth of cut for dressing increases the cutting-edge density, and this improves the ground surface roughness. Furthermore, spark-out for dressing releases the grains that are damaged with dressing, and this increases the cutting-edge density. However, excessive spark-out for dressing makes the working surface easy to load, consequently, and the ground surface roughness becomes worse.
