TEMPERATURE MEASUREMENT METHOD AND TEMPERATURE MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a temperature measurement method and a temperature measurement device allowing grasping of the temperatures of rotary tools such as a cutting tool in actual cutting and a welding torch in welding in real time to more accurately evaluate cooling performance of cutting oil agent and cooling water or the like than a conventional way.SOLUTION: A temperature measurement method uses: a rotary holding body which is capable of rotating with a rotary shaft as a center and has a hollow hole formed to extend from a tip to a rear end along the rotary shaft; and a rotary tool which is connected to the rotary holding body and has a through hole formed coaxially with the hollow hole. The temperature measurement method includes: a process for mounting a temperature measurement section in the vicinity of the through hole of the rotary tool; a process for measuring the temperature of the rotary tool rotating coaxially with the rotary holding body using the temperature measurement section; and a process for receiving a measurement result of the temperature measurement section through an electronic substrate in the order.
