Abstract: In order to perform the grinding process in dry condition, the chip formation needs to be optimised so that the friction between the grinding wheel and the workpiece is minimised. The Institute of Grinding and Precision Technology (KSF) conducts a profound research to find out optimal conditions in order to apply the dry machining to plunge cylindrical grinding. Structuring of the wheel topography in a new manner through which the number of kinematic cutting edges are reduced, is the new concept applied in this investigation. Through the new structure of the wheel, the size of the chip thickness which depends on the material specification, the grit size and the grinding parameters – will be optimised. The obtained results show that compared to the case of employing conventional wheels, the application of the special structured wheel in plunge cylindrical dry grinding can reduce the grinding forces.

Keywords: dry grinding; plunge cylindrical grinding; grinding wheel topography; structuring; structured grinding wheels; chip formation; grinding forces.
