A calibration method for machine tools comprises: providing a workpiece on a machine tool; rotating the workpiece around a first rotation axis parallel to a main shaft of the machine tool and processing the workpiece by a first machining mode; measuring a first dimensional error of a shape of the workpiece along directions of first and second linear axes perpendicular to the first rotation axis; calculating a positional error of the first rotation axis according to the first dimensional error; rotating the workpiece around a second rotation axis perpendicular to the main shaft and processing the workpiece by a different second machining mode; measuring a second dimensional error of the shape of the workpiece along a direction of a third linear axis perpendicular to the second rotation axis; calculating a positional error of the second rotation axis according to the second dimensional error.

Calibration method and calibration system for machine tools

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.
