The stylus method is analyzed theoretically by a statistical approach for the purpose of clarifying the effect of stylus shape on the measured grain cutting edge density seized by the stylus, and the degree of agreement is investigated experimentally between the measured grain cutting edge density by means of stylus method and that obtained by means of scratch method. Results are summarized as follows: When using conical stylus, measured density of grain cutting edges seized by the stylus is not identical with that of grain cutting edges existing within the grinding wheel, so that a relationship equation between the two is derived the oretically. When using knife-edged stylus, meas ured grain cutting edge density obtained by the stylus agrees with the grain cutting edge density in the grinding wheel approximately, although the agree ment is limited in the grinding wheel surface layer The limited depth of grinding wheel varies win width of knife-edged stylus and 0.3 mm is obtainec as an appropriate width. Experimental results o wheel surface topography by means of stylus methoc show an agreement with those obtained by means of scratch method in the grinding wheel surfact layer.
