In order to measure cutter temperature, the on-line thermocouple temperature measurement system was proposed. In this system, temperature sensing element thermocouple was welded in the flank face close to the cutting edge with double bare wires welding way. With this method, this system has advantages of a single point temperature measurement and no effect on cutter temperature distribution. For a higher sampling rate, two AD were used to sample alternately; and for the convenient signal transmission when the cutter is rotating at high speed, wireless transmission was adopted to transmit thermocouple output signal and cold side temperature signal to the host computer. After temperature compensation to the cold side, the compensated temperature will be real-time displayed, stored and played back. System measurement range is 0 ~ 1300 ° C, and the measurement uncertainty is 0.58%. For 8000rpm rotational speed of XH714D machine, experimental results show that the system can measure cutter temperature online, and has advantages of low cost and great practicability.
