Numerical control device

The invention provides a numerical control device, comprising: an operation pattern storage unit (11) which stores operation patterns which include instructions which execute operations upon a peripheral device using an axle configuration or a unique M-code of the peripheral device or a movement quantity of the peripheral device as a variable; a machine information storage unit (14) which stores machine information wherein a value for the variable is associated with the axle or the unique M-code of the peripheral device; a program analysis unit (12) which, if an instruction in an accepted numerical control program is an instruction for the peripheral device, acquires an operation pattern corresponding to an argument which indicates the operation pattern, and transfers the same together with movement quantity in an argument which indicates the movement quantity of the peripheral device to a peripheral device operation generating unit (15); the peripheral device operation generating unit (15) which assigns either the corresponding machine information or movement quantity to each variable of the instruction which configures the acquired operation pattern and generates a peripheral device instruction; and a numerical control unit (16) which generates a movement instruction from the peripheral device instruction with respect to the axle which configures either the machine tool or the peripheral device.
