Abstract
In grinding processes, the surface profile of a grinding wheel is an important factor to determine the surface roughness of the work after grinding. There are many studies which deal with measuring the surface profile of the grinding wheel using various methods. However, the height of cutting edges of the grains hasnot been clarified absolutely because these methods used in them were two dimensional. Consequently, it has been impossible to estimate the vary of height of cutting edges by wear. The aim of this study is to measure the surface topography of the grinding wheel in three dimensions. Additionally, the relation between the surface topography of a grinding wheel and the surface roughness of the work after grinding is clarified in order to improve the grinding conditions. Specially, this paper describes the new measuring system developed using the laser stylus unit on the machine in order to measure the surface topography of a grinding wheel. By this system, it is possible to measure the surface of the grinding wheel in circumference. It is shown that these measurements are very precise in 0.8μm.
