Title:
THERMAL DISPLACEMENT MODEL TRAINING DEVICE, THERMAL DISPLACEMENT ESTIMATION DEVICE, PROCESSING SYSTEM, AND PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/228253
Kind Code:
A1
Abstract:
This thermal displacement model training device (2) is characterized by comprising: a training data acquisition unit (21) which acquires training data in which input data including at least temperature data that represents the temperature of a machine tool in time series is associated in time with thermal displacement data that represents a thermal displacement amount of the machine tool in time series; a data set generation unit (22) which generates a data set obtained by extracting a portion of the training data; and a training unit (23) which uses the data set to generate a trained thermal displacement model for estimating the thermal displacement amount from the input data of the machine tool, wherein the data set generation unit (22) generates a plurality of data sets so that time lengths of time periods extracted from at least two among the plurality of data sets are different from each other.
