“…Graham and Baul [58] and also Kannapan and Malkin [59] suggested that the size effect in grinding could be attributed to the occurrence of a relatively greater proportion of sliding and ploughing energy when the uncut chip thickness is decreased. Rowe [60] gave a sliced bread analogy.…”

The aim of the investigation was to achieve a method of assessment of vitrified CBN wheels for precision grinding based on investigation of relationships between the changing features of grinding wheels and grinding performance.Feasible measurement and observation techniques for the changing topographical features of vitrified CBN wheels in grinding were investigated. Comparisons included measurement resolution, measuring depth, ease of application, and data analysis and interpretation. The optical interferometer was found to be good for measurement of vitrified CBN wheel topography, and a microscope was found to be helpful for understanding the measurement results. In addition, replication techniques were compared and analyzed. A newly developed replica material with high resolution (0.1 microns) and easy operation, Microset 101, was employed as a negative replica material in the experimental work.A set of parameters was defined which describe the wheel characteristics including active cutting edge density, cutting edge dullness, effective porosity volume ratio and wheel scratch hardness. A parametric study was made of the effects of wheel characteristics on CBN grinding performance including grinding force, grinding temperature, wheel life and workpiece accuracy using elevated wheel speed with different workpiece materials.An experimental study was carried out with grinding wheels having different grain sizes, pore volumes, and wheel hardness values for grinding different workpiece materials. Experimental results are discussed in relation to the theoretical understanding of the process. The effects of varying wheel structure, wheel speed and workpiece material are discussed in relation to grinding power, workpiece surface roughness, size error and wheel topography. IThe mechanics of grinding wheel wear and loading are reviewed. Grinding wheel wear and loading trends were predicted. Suggestions are made for the avoidance of grinding wheel wear and loading. II
