Zusammenfassung:	To determine the capability of a rotary grind stone using imaged abrasive grains.SOLUTION: Abrasive grains 14 used for a rotary grind stone are placed on a transparent plate 13, and are imaged from the top and from the bottom of the transparent plate 13. The shapes and the sizes of the abrasive grains 14 are determined from the image data and are grouped so that the abrasive grains 14 are graded. The ratios of the amounts of the graded abrasive grains in the groups are calculated. The ratios of amounts of the graded abrasive grains are averaged and the capability of a rotary grind stone using the abrasive grains 14 is determined.SELECTED DRAWING: Figure 1 【課題】撮影された砥粒を用いた回転砥石の能力を判別すること。【解決手段】回転砥石に用いられる砥粒１４を透明板１３上に載置する。その透明板１３の上下から透明板１３上の砥粒１４を撮影する。その上下の画像データから、砥粒１４の形状および大きさを判別し、その形状および大きさをグループ化して砥粒１４を分級する。分級された各グループの砥粒量の割合を算出する。そして、分級された砥粒量の割合を平均化し、この砥粒１４を用いた回転砥石の能力を判別する。【選択図】図１
