Abstract: A tangential grinding resistance measuring method includes obtaining an abrasive grain section area which is at a predetermined infeed depth from the highest top surface of abrasive grains on a grinding wheel; calculating the tangent of a half vertex angle of a conical model for cutting edges of the abrasive grains which model takes the abrasive grain section area as its bottom surface and the predetermined depth as its height; setting grinding parameters; and calculating a tangential grinding resistance from the grinding parameters and the tangent.
