The machine tool control device is provided with a calculation unit for estimating, on the basis of the tool path for machining using a tool and information on the workpiece, the portion of the tool that will form the final machined surface. The control device is provided with a feed rate-setting unit for estimating the fastest moving point, among multiple moving points contained in the portion that will form the final machined surface, for which the relative velocity of the tool with respect to the workpiece will be maximal and setting the feed rates for the machine tool movement shafts so that the relative velocity of the fastest moving point is at or below a previously specified relative velocity. |
