The transferring of electronic signal from rotating work piece or cutter presents a challenge problem. In this paper, a wireless communication method is proposed to transmit signal from rotating bodies. The corresponding device including the signal input & transmission module and the signal receiving and processing module was fabricated. The working principle of the wireless system is introduced, and a series of experiment is set up to calibrate the system accuracy and to measure the cutting temperature of the rotating work piece. The experimental results show that the wireless system has a satisfactory reliability and temperature measurement accuracy.
