Abstract
In this paper, the quantitative measurement method of the cutting edge density based on the working surface profile, which can be measured on the machine, is proposed.In addition, the validity is clarified based on the experimental and analytical examination.As a result, the following were clarified:The cutting edge density can be estimated from the distribution of the maximum height of the grain and the peripheral thickness of the grain layer, which is in contact with the workpiece surface.The grain height distribution can be estimated from the peak height distribution of the profile and the grain diameter.The peripheral thickness of the grain layer can be determined from the change in the peak height distribution on the working surface with grinding.The estimation validity is experimentally clarified from the relationship between the change in the cutting edge density and in the working surface.
