Abstract
A thermal error compensation method for machine tools is disclosed, which comprises the steps of: disposing at least a thermal sensor at positions neighboring to the at least one heat source of a machine tool; driving the machine tool to operate under a specific operation condition for enabling the at least one heat source to generate heat; generating a thermal signal according to the temperature detected by the at least one thermal sensor; using a heat conducting calculation unit to access the thermal signal and the information relating to the specific operation condition to be used in a calculation for obtaining and thus outputting at least a node temperature; and using an error compensation unit to access the at least one node temperature to be used in a calculation for obtaining thermal error compensation values for the machine tool.
