Transient temperature measuring tool for PTFE cutting machining and using method thereof

The invention discloses a transient temperature measuring tool for PTFE cutting machining and a using method of the transient temperature measuring tool. The tool comprises a diamond tool bit, a tool base and a thermocouple dot matrix. The diamond tool bit is fixed to a mounting groove formed in the tool base. And the thermocouple dot matrix is assembled on a mounting groove on the tool base and is positioned in a gap between the tool base and the diamond tool bit. The device can be applied to measurement of the transient cutting temperature of the PTFE material, the multiple thin film thermocouples are installed on the surface of the installation groove in the tool base, the insulating heat conduction films are prepared on the surface of the diamond tool bit and the surface of the tool base, and therefore the temperature of the diamond tool bit in the machining process is monitored in real time; the thin film type sensor has the advantages of small thermal capacity, small size, high response speed and capabi
