It was always difficult to transmit the thermoelectric power signal collected through thermocouple from highspeed rotary tool into static temperature measurement equipment. Therefore, two methods are used to achieve this purpose. One was signal temporary storage way. Thermoelectric power signal collected through thermocouples was stored temporarily in the thermoelectric power acquisition card which rotated along with the cutter. After end of a cutting process, signal was transmitted to static temperature measurement equipment through lines. An advantage of this method was that the signal transmission process was stable; while the disadvantage was that the signal collected was not able to be displayed timely. Another method was wireless transmission way. The signal was transmitted timely to the personal computer (PC) system of temperature measurement, wirelessly, and then the thermoelectric power signal was converted to a temperature value, and achieved display of cutting temperature timely. Two sets of temperature measurement system have been manufactured, and the stability of wireless transmission is confirmed after a series of experiments.
