Title:
THERMAL DISPLACEMENT CORRECTION DEVICE
Document Type and Number:
Japanese Patent JP2021104564
Kind Code:
A
Abstract:
To provide a technique for reducing labor and time required for learning work when performing thermal displacement correction in an electric spark machine using a machine learning technique.SOLUTION: A thermal displacement correction device 1 comprises: a temperature acquisition unit 110 for measuring a temperature of an environment in which a machine is installed and a temperature of each part of the machine; a thermal displacement amount acquisition unit 130 for acquiring a thermal displacement amount of the machine; a temperature difference calculation unit 120 for calculating a temperature difference between at least two temperatures of temperatures measured by the temperature acquisition unit 110; and a learning unit 140 for generating a thermal displacement correction model for estimating output data from input data by machine learning on the basis of teacher data which takes as the input data the temperatures measured by the temperature acquisition unit 110 and the temperature difference calculated by the temperature difference calculation part 120 and which outputs the thermal displacement amount acquired by the thermal displacement amount acquisition unit 130 as the output data.SELECTED DRAWING: Figure 2
