May 01 2020 The framework in Fig. 1 illustrates the overall procedure to calculate the grinding wheel path for complex end mill groove manufacture. When the groove and grinding wheel geometries are applied as the input 4 curve equations are established to mathematically define the groove.
stirred media mills requires the simultaneous modelling of grinding media a moving internal stirrer and slurry. In the present study a novel approach for modelling the physical interactions between slurry grinding media and mill structure in a stirred media mill is presented. The slurry is modelled with the particle ﬁnite element method .
