Abstract:
A numerical controller has a tool retraction function for retracting a tool so as not to damage the machined surface of a workpiece when machining of the workpiece by a machine tool is interrupted. The numerical controller identifies a machining method for the machining to be interrupted when a command to interrupt the machining is detected, determines the direction of the retraction of the tool, based on the identified machining method and the feed direction and the rotation direction of a spindle in the machining to be interrupted, and generates a movement path of the tool in the determined retraction direction.

Claim (Index 1):
A numerical controller controlling a machine tool which includes a spindle and at least two feed axes for relatively moving the spindle and a workpiece and machines the workpiece by rotating a tool mounted on the spindle in accordance with a machining program,\n wherein the numerical controller is configured to retract the tool from the workpiece with currently performed machining interrupted, based on a command to interrupt the machining while the workpiece is being machined, and wherein the numerical controller comprises:\n a stop command detection unit configured to detect the command to interrupt the machining; \n a machining method identification unit configured to identify a machining method for the machining to be interrupted when the command to interrupt the machining is detected by the stop command detection unit; and \n a retraction path generation unit configured to determine the direction of the retraction of the tool, based on the machining method identified by the machining method identification unit and the feed direction and the rotation direction of the spindle in the machining to be interrupted, and to generate a movement path of the tool in the determined retraction direction.
