    n grinding with vitrified cubic boron nitride (CBN) wheels, frequent dressing should be avoided. It is expensive in time and also in consumption of an expensive abrasive. Wheel loading is a main cause of wheel redressing especially for difficult-to-grind materials such as Inconel 718, and must therefore be prevented. One solution to prevent loading is to employ an open wheel structure in order to help coolant delivery to the grinding zone and provide more space for chip-flow and swarf removal. The grinding performance of high-porosity CBN wheels is compared with that of a medium-porosity CBN grinding wheel. Analysis and discussion of performance is presented in terms of observations and measurements of the changes in wheel topography.
