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 () includes a sequential analysis control unit (), an advance analysis control unit (), a correction value calculation unit (), a change amount calculation unit (), and a mode switching unit (), 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).
