Correlation of grinding wheel topography and grinding performance: A study from a viewpoint of three-dimensional surface characterisation

Abstract Grinding wheel topography and its grinding performance was studied using an experiment, in which the truing operations were varied according to a factorial design. The correlation of wheel topography and its performance is characterised through the employment of three-dimensional surface characterisation parameters. The density of summits Sds, the summits curvature Ssc, and the root-mean-square roughness Sq are used to characterise the density of abrasive grains, the sharpness of abrasive grains, and the coarseness of the wheel, respectively. A new criterion for selecting the optimal sampling interval ( S al / 4 ≤ Δ ≤ S al / 3 ) is also proposed.
