The basic process parameters in grinding processes are the cutting speed v c, the feed velocity v f, the depth of cut a e, and the width of cut a p (see Fig. 1, see also Denkena and Tönshoff 2011).The cutting speed is in general equal to the circumferential speed of the grinding wheel.
The grinding is the last stage of comminution in a mineral processing plant, responsible for reducing particles in size by mechanisms of fragmentation, impact, compression, and shear. Moreover, it is one of the stages that requires greater focus due to the more energyconsuming and major investments requirements. The grinding is considered very important for the mineral concentration process ...

The most important point in simulation is to get the removals from the workpiece surface at a discrete time point. In this context, the simulation of the grinding process is more difficult than those precise operating processes like milling, because the removal of the surface can not be obtained directly by the swept volume through CAD data and tool shape.
