Abstract:
Provided is a machine tool control device which reduces a processing burden of calculating a thermal displacement amount, avoids decrease in processing speed, and increases accuracy of machining a workpiece.A machine tool control device (100) includes a sequential analysis control unit (110), an advance analysis control unit (120), a correction value calculation unit (130), a change amount calculation unit (140), and a mode switching unit (150), and operates a machine tool (M) by executing a machining program that is corrected on the basis of a thermal displacement amount occurring on components constituting the machine tool (M) to enable highly accurate machining of a workpiece (W).
