Abstract
A thermal compensation system for machine tools includes a thermal compensation-monitoring device and a cloud processing device. The thermal compensation-monitoring device receives a plurality of temperature signals of a workpiece and corresponding processing tolerance data to build or update a thermal compensation database. The cloud processing device provides a thermal compensation model, and applies the model with the characterized temperature signals and the tolerance data to generate a compensation value so as to decide whether or not to modify the model or to run a compensation is necessary.
