Title:
MACHINE TOOL THERMAL DISPLACEMENT COMPENSATION DEVICE AND COMPENSATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/149765
Kind Code:
A1
Abstract:
The present invention relates to a machine tool thermal displacement compensation device and compensation method comprising: using a temperature sensor so as to calculate a direct compensation amount through direct calculation; calculating an indirect compensation amount through machine learning with respect to indirect factors, so as to calculate a final compensation amount through a non-reflected portion, unlike a conventional method, by means of the direct compensation amount and the indirect compensation amount, thereby automatically calculating a compensation amount in real time according to the thermal displacement of a structure unit; and immediately reflecting the calculated compensation amount so that a workpiece can be machined.
