Experimental study of wear of the working surface of a grinding wheel

An increase in productivity and quality of grinding is largely restrained by the lack of universal numerical methods of calculation of optimal process conditions and static characteristics of the cutting tool. This is due to the fact that grinding process parameters vary significantly over the lifespan of a grinding wheel (GW). One of the important but poorly known factors is the shape of the GW working surface. The 3D experimental modeling made it possible to develop a model describing the wear shape of the GW working surface and the dependence of the GW-workpiece contact area on the GW wear. The results of the study will enable more accurate data about cutting forces, tool wear rates, and other parameters of the grinding process. They will also make it possible to assess the dynamics of the parameters over the GW lifespan. The results can be used in engineering and other industries applying grinding of metals.
