Numerical control device

A numerical control device includes at least an operation-pattern storage unit that stores operation patterns each including commands for causing operations by a peripheral device to be executed, the commands using a shaft configuration of the peripheral device, a unique M code, or a moving amount of the peripheral device as variables, a machine-information storage unit that stores machine information in which a value with respect to each of the variables is specified for a shaft of the peripheral device or for the unique M code, and a program analysis unit that when a command in a received numerical control program is a command for the peripheral device, acquires an operation pattern corresponding to an argument indicating the operation pattern and delivers the operation pattern to a peripheral-device operation generation unit together with a moving amount indicated by an argument indicating the moving amount of the peripheral device.
