A controller for a machine tool outputs an operation instruction signal to the machine tool. The machine tool transmits a signal indicating that the instructed operation is compete. The controller determines a response time of operation to be a difference in time between a point in time when the numerical controller outputs an operation instruction signal and a point in time when the numerical controller receives a signal from the machine tool. When the response time of operation exceeds a preset value, the numerical controller determines that a corresponding maintenance component needs to be replaced and informs a user of the need for replacement by means of a display unit.

Machine tool including numerical controller with function to determine replacement time for maintenance component

A machine tool includes a rotary table on which a workpiece is mounted, a clamping mechanism for clamping the rotary table against rotation, and a sensor for detecting completion of a clamping operation of the clamping mechanism. A numerical controller for controlling the machine tool calculates the time required for actual operations of the clamping mechanism, taking into account beforehand the processing time for processing a feedback signal from a sensor and the time until the next operation of the machine tool. By controlling the clamping mechanism based on the calculated required time, the cycle time of clamping or unclamping operations is shortened.
