Abstract

The invention belongs to the field of cutting tools, and particularly discloses a cutting tool with an embedded thin-film temperature sensor and a preparation method. The cutting tool is prepared by the following steps: preparing two cutter bodies comprising a first cutter body and a second cutter body, grinding and polishing, and washing for future use; preparing the thin-film temperature sensoron the upper surface of the first cutter body; plating an insulating thin-film layer on a prepared pattern on the upper surface of the first cutter body, and sputtering a metal thin-film layer in an area, without preparing the pattern, in the middle of the upper surface of the first cutter body; placing the second cutter body on the upper surface of the first cutter body, fixing positions of the first cutter body and the second cutter body through a mould, and preparing by high-temperature high-vacuum isostatic-pressing sintering, to obtain the cutting tool; performing tool nose decoration onthe cutting tool, to obtain the needed cutting tool. The cutting tool with the embedded thin-film temperature sensor is capable of realizing temperature field real-time in-situ on-line measurement, and has the advantages of high temperature measurement reliability, rapid response rate, high space resolution and long service life of the temperature sensor and the like.

Description

technical field [0001] The invention belongs to the field of cutting tools, and more specifically relates to a cutting tool with an embedded film temperature sensor and a preparation method thereof. Background technique [0002] Metal cutting has always been one of the most important and active methods of forming machine parts in manufacturing. Due to the large amount of cutting heat generated in the cutting process, the cutting temperature rises, which directly affects the thermal deformation of the workpiece, the quality of the machined surface and the life of the tool. However, there are extremely steep temperature and stress gradient changes in the narrow cutting area. Due to the limitations of size and measurement environment, it is difficult for existing temperature sensors to go deep into or close to the cutting area, so as to realize real-time and accurate temperature measurement and recording during processing. Therefore, in order to quickly and accurately monitor ...
