Experimental investigation of wear mechanisms with electroplated CBN wheel

Wheel wear in grinding is a sophisticated phenomenon which can affect the whole grinding process profoundly. In this study, different types of wear mechanisms such as attritious wear, grain fracture and the pullout of the abrasive grains have been studied on a single layer electroplated cubic boron nitride (CBN) grinding wheel. The effect of wear mechanisms on the grinding forces and the workpiece surface have been taken into account. Surface grinding experiments were conducted on Inconel 718 and the change in the wheel topography and the grinding behavior were investigated. Grits were individually investigated and wear mechanisms on them are discussed. Individual grit investigation provides more detailed analysis of wear.
