研削過程のシミュレーション

Abstract

Basing on the results of scratch-deformation experiment using a single abrasive grain, the grinding process performed by the abrasive belt involving a large number of cutting edges which differ in shape was analyzed in view of the depth of cut. This analysis was done using computer simulation and the results were examined from the grinding experiment. Regarding these results, the depth of cut which coincides with the actual value is calculated by substituting the machining conditions, the variables indicating the state of the cutting edges of the coated abrasives and the decided constant obtained from the mechanical properties of the workpiece to the simulation of the grinding process. Moreover, it may be possible to predict the life characteristic of the abrasive belt in the case of grains changing due to the wear only. The difference of the depth of cut depending on the state of contact between the belt and the workpiece is made clear systematically from the change in the number of cutting edges per contact area.
