In the grinding process due to the elastic deformations of grinding machine and grinding wheel the ground depth of cut is smaller than the applied depth of cut Consequently the ground depth of cut has to be controlled in sparkout grinding process However the cycle time in sparkout grinding process is not easy to be estimated From such a viewpoint in this study using specific
Request PDF Estimation of Grinding Cycle Time Taking into Account Specific Grinding Force In the grinding process due to the elastic deformations of grinding machine and grinding wheel the
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 andor the grinding time has to be considered by the elastic deformations and the thermal expansions
