A milling cutter temperature measuring technique was devised using garter spring pickups and standard thermocouples positioned at the back of inserts. Temperature signals as many as eight teeth were recorded simultaneously. It was found that the average cutting temperature of a multitooth cutter was higher than a flycutter at the same cutting conditions. The difference between one and two-tooth cutters was the largest and it tended to decrease when the number of teeth increased. The experimental error was thoroughly analyzed. The standard error for a flycutter was found to be about one half of that for multitooth cutters. Analysis of the temperature responses and the experimental errors indicated that a two-tooth cutter rather than a flycutter should be used to evaluate the performance of a multitooth cutter.
