The objective of the present invention is to provide a numerical control device and control method with which it is possible for hole opening to be performed at high speed and with low vibration. This numerical control device for performing hole opening continuously at prescribed intervals in a workpiece, using a machine tool, is provided with: a positioning unit for moving a hole opening tool of the machine tool to a hole opening position of the workpiece, and positioning the hole opening tool; a cutting unit; a retracting unit for retracting the hole opening tool from the workpiece; and a program executing unit for executing a machining program for causing the machine tool to continuously machine the workpiece, by sequentially executing movement axis operation using the same control scheme for the processing performed by the positioning unit, the cutting unit, and the retracting unit.
A numerical control device for causing a machine tool to perform a drilling process of continuously cutting holes at predetermined spacings in a workpiece, the numerical control device comprising:
