Ground surface imperfections are often attributed to periodical marks caused by vibration in grinding. According to the mechanism by which the marks were formed, there are various characteristics which can be important clues to diagnosing the type of grinding vibration and making appropriate counterplans. By classifying the marks due to each type of grinding vibration experimentally as well as theoretically, they can be divided into two categories depending on whether the marks were formed chiefly by a shape error or by a roughness variation. In addition, the relationship between the presence of the marks and the speed ratio, and the marks'inclination to the wheel axis are generalized to correspond with the different grinding processes and types of grinding vibration. The generalized relationships make it possible to narrow down the possible causes to a few types of vibration. Also, an optical method which is necessary for the diagnosis is proposed for measuring the characteristics of the marks. Together with the principal counterplans for each type of grinding vibration, a system of knowledge for vibration diagnosis has been obtained.
