  • Estimation of the Grinding Time by Means of the Grinding

    In grinding operation elastic deformations of the grinding machine and the grinding wheel induce a residual stock removal of workpiece. On the other hand thermal expansions of the workpiece and the grinding wheel increase the depth of cut. Therefore calculation of a ground depth of cut and/or the grinding time has to be considered by the elastic deformations and the thermal expansions.
