Abstract
In this paper, a method for measuring the cutting edge density on grinding wheels is proposed based on the working surface profile and the grinding force, and then its usability is also examined by applying it to the actual grinding process. The results indicated that the cutting edge density can be determined based on the grain height distribution and the thickness of the effective cutting edge layer. The grain height distribution can be estimated from the measured peak height distribution by narrowing the height range of distributions while maintaining the total frequency. On the other hand, the depth of the effective cutting edge layer can be determined by matching the estimated grinding force calculated from the supporting stiffness of the grain and the grain height distribution with the measured grinding force. From the experiment, the relationships between the ground surface roughness and the cutting edge density were shown to agree well with the grinding theory.
