Abstract
A numerical control apparatus includes an imaginary-Y-axis control unit configured to execute an imaginary Y-axis control mode which is a mode for converting an X-Y axes movement command in a machining program described in a program coordinate system into a command in a machine coordinate system including X-H-C axes and for driving the X axis, the H axis, and the C axis in association with one another according to the converted command, an acquiring unit configured to acquire, when an emergency stop occurs during the imaginary Y-axis control mode, present positions of the X axis, the C axis, and the H axis at the time when the emergency stop is released, and a restoring unit configured to restore a present X-axis coordinate position and a present Y-axis coordinate position in the program coordinate system from the acquired present positions of the X axis, the C axis, and the H axis.
