Online Estimation System of Grinding Wheel Status Based on D-S Evidence Theory

Abstract:

Automated quality control of aspheric optical lens is a development tendency of precision grinding manufacturing in the near future. Grinding wheel status changes as the grinding time elapses and it has a close relationship with the ground surface. Therefore, an online estimation system of grinding wheel status is studied and established in this paper in order to judge the wheel’s life-cycle automatically and dress it in a proper occasion. Several representative process quantities are selected and characters of the dynamical signals are abstracted to provide all-around information about the evolvement of grinding wheel status. Dempster-Shafer evidence theory is employed by the estimation system to acquire a reliable decision about grinding wheel status.
