The thermo-couple method, which is one of measuring methods of grinding wheel surface topography, is analyzed theoretically and experimentally by using a statistical approach. The theoretical analysis is made on the number C_m of effective cutting edges per unit wheel surface area, and the following effects on C_m are discussed ; (a) grinding conditions, (b) shape dispersion of grain cutting edges, (c) positional distribution pattern of grain cutting edges, (d) elastic and plastic behaviors between grain and workpiece. The experiments are carried out for three different sizes of constantan wire under the condition of surface plunge grinding, and the relationships between the number N_m of thermo-electric pulses and the following two factors are discussed ; (a) grinding conditions, (b) width of thermo-couple hot junction. The experimental number N_m shows a good agreement in a qualitative sense to the theoretical one.
