US 2025/0178146 A1 · MACHINING TOOL THERMAL COMPENSATION SYSTEM BASED ON AN AGGREGATION MODEL AND METHOD THEREOF

Abstract

A machining tool thermal compensation system based on an aggregation model includes a calculating module and a processing module. The calculating module executes a first thermal compensation model and a second thermal compensation model. The first thermal compensation model is only related to motor temperature change and the second thermal compensation model is only related to environmental temperature change. The processing module executes an aggregation model based on Kalman filter. The calculating module inputs the motor temperature of a target machining tool at a time point into the first thermal compensation model to generate a first compensation value and inputs the environmental temperature of the target machining tool at this time point into the second thermal compensation model to generate a second compensation value. The processing module executes the aggregation model according to the two compensation values to generate a modified compensation value of this time point.
