Grinding is one of the excellent processing methods that can obtain high processing accuracy and good surface roughness. However, when using a grinding tool such as a grindstone at a production site, the machining accuracy of the machined surface may differ even if the same product is used. One of the causes is the difference in dispersibility of abrasive grains. Until now, the distribution of the abrasive grains of the grindstone has been evaluated using a laser sensor and image processing of the photograph of the grindstone surface, but in most cases, the abrasive grain layer is a single layer, It is an evaluation in a limited range on the surface of the grinding wheel, and extensive evaluation has not been performed on the grinding wheel. In this report, the entropy evaluation method that has been used in our laboratory up to recent to evaluate the dispersibility of abrasive grains in a grinding belt was applied to a grinding wheel with multiple abrasive layers. As a result, the possibility of evaluating the grain distribution of the grinding wheel was shown by using the entropy evaluation method.
