Abstract
In cutting temperature survey, in order to reflect the temperature change of cutting area accurately, the cutting tool sensor should have good technical characteristic. In this paper, one kind of automatic calibration system has been developed which could be used to investigate the technical characteristic of the multi-layered laminated thin film thermocouple cutting temperature sensor, this system selects Platinum-chip temperature sensor (concrete model: EN60751) as the standard temperature sensor, uses the AD524 precise amplifier chip building amplifying circuit and compiles the software with LabVIEW. This paper intends to investigate the static characteristic of the multi-layered laminated thin film thermocouple cutting temperature sensor system, the result shows that the Seebeck coefficient is 66.9 μV/°C, and the nonlinear error of fitting is smaller than 0.32%. This research has paved the way for future studying of thin film thermocouple cutting temperature sensor technology characteristic.
