“…In this study we used the following time-domain statistics: RMS (1), mean value, standard deviation, variance, and the one-step autocorrelation function [37]. The one-step autocorrelation function, as expressed by (6), denotes the correlation between a data point and the subsequent data point and thus better reflects the periodic change of a signal. The signals were calculated based on the time series to reveal feature changes along the grinding process.…”

“…Hard and brittle materials are comparable to the abrasives of the grinding wheel in terms of hardness; over the course of the grinding process, grains become dull from wear. When this happens, the chips produced from cutting fill the pores of the wheel surface, flattening the surface and rendering the wheel incapable of cutting [6]. If a flattened grinding wheel continues to operate, however, the normal force (FN) overtakes the tangential force (Ft), resulting in damage to the workpiece and ruptures in the wheel.…”

“…Since a diamond grinding wheel is sintered with diamond grains and metal binders, the sintered surface is distributed with many abrasive grains similar to small cutting tools and pores that load chips [4]. Furthermore, to grind hard, brittle materials, a grinding wheel must be chosen with good self-sharpening ability and suitable grinding parameters; nevertheless, good sharpening ability implies a high wear rate for the abrasives.…”
