## Abstract

A numerical control device 102, in which a processor 102a numerically controls a machine tool 103, is provided with an external storage unit 201 for storing machining data conforming to various shape patterns, input means 202, an editing processor 102c and an internal memory 102d, in order to implement a function for the creation of numerical control information. Machining data, corresponding to a part code entered from the input means 202, is read out of the external storage unit 201c. The editing processor 102c creates numerical control information, which is stored in the internal memory, from the machining data and, e.g., numerical values input from the input means 202.
