The measuring accuracy of grinding wheel surface topography is investigated by Monte Carlo simulation for the following five indirect measuring methods from the viewpoint that the elastic and plastic behaviors in the grain-work interface may have an influence on the measured density of grain cutting edges : razor-blade method, thermo-couple method, scratch method, cluster overcut fly grinding (COFG) method, and conventional grinding method. From the simulation, it is clarified that the number of grain cutting edges obtained from the razor-blade method, in which total effective cutting edges are the targets to be measured, and that obtained from the thermo-couple method, in which effective cutting edges on the reference section are the targets, are more influenced by the elastic and plastic behaviors than those obtained from COFG method, scratch method, and conventional grinding method, in which effective cutting edges for roughness generation are the targets. In addition to the simulation, the following is verified by some experiments : the number of grain cutting edges seized by the thermo-couple method is larger than that seized by conventional grinding method.
