Abstract
A numerical control device that controls a machine tool that machines work by moving a tool relatively to the work on the basis of a machining program includes a analyzing unit that analyzes the machining program and generates movement command data, a detecting unit that detects abnormality during the machining, a retract control unit that supplies, when abnormality is detected, an operation command for a retract operation for retracting the tool from the work, and an integrating unit that integrates a movement amount of the tool based on the supplied operation command. The analyzing unit executes a tool retraction program for moving the tool or the work to a predetermined position after adding the movement amount of the tool integrated by the integrating unit to a coordinate value of the tool on the machining program to update the coordinate value at a point in time when the retract operation ends.
