  • Quantification Method of Cutting-Edge Density Considering

    In this study the quantification method of the cutting-edge density is proposed because of its close relation to the grinding mechanism. The cutting-edge density depends upon not only the grain distribution but also the thickness of effective cutting-edge layer. Therefore the quantification of the cutting-edge density requires measuring not only the profile but also the grinding force.
