divided in three groups: the process, the machine and the grinding quality. DoE results revealed that the parameters interact in a complex manner and depends on the responses. Therefore, to gain a better understanding of the grinding process of sapphire, the interactions between parameters have also to be taken into consideration.
The experiments were conducted on the surface grinding machine with a cylindrical grinding attachment at different combinations of grinding process parameters. Experiments were performed at two values of grinding wheel speed, 1400 and 2800, for both surface and cylindrical grinding .
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.
Prediction of patterns on the freeform surface prior to texturing process by 3D simulation built over mathematical model is very crucial. If the textured patterns are predictable, various grinding parameters can be determined easily. This paper presents a 3D simulation environment for the prediction of patterns on freeform surfaces.

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 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.
