Title:
THERMAL DISPLACEMENT CORRECTION DEVICE, AND COMPUTER-READABLE RECORDING MEDIUM IN WHICH PROGRAM IS RECORDED
Document Type and Number:
WIPO Patent Application WO/2023/238192
Kind Code:
A1
Abstract:
A thermal displacement correction device according to the present invention comprises: a temperature data acquisition unit that acquires temperature data pertaining to the temperature of each part of a machine; a displacement data acquisition unit that acquires displacement data pertaining to the amount of thermal displacement of the machine; a temperature data storage unit that stores temperature data used in machine learning; a temperature data comparison unit that compares the temperature data measured by the temperature data acquisition unit and the temperature data stored by the temperature data storage unit; and a determination unit that, on the basis of the result of comparison by the temperature data comparison unit, determines whether it is necessary to measure the amount of thermal displacement of the machine using the displacement data acquisition unit.
