PROBLEM TO BE SOLVED: To stably and allocate a fixed portion of processes of a processor to control processes of peripheral equipment, without fail, without increasing the complexity of software or hardware. SOLUTION: A numerical control device for controlling a plurality of operations, regarding servos 3, 4 and the peripheral devices includes the processor 13; a system control cycle timer 111; a system control cycle interrupt generator 112, which generates a first interruption request to the processor 13 at a system control cycle; a servo-synchronizing cycle timer 122 which is different from the system control cycle timer 111; a servo-synchronizing cycle interrupt generator 123, which generates a second interrupt request to the processor 13 at a servo-synchronizing cycle; a timer cycle divider 123a, which divides the cycle of the second interruption request into a predetermined number of sections; and a servo-synchronizing cycle interrupt generator 123, which generates a third interruption request for controlling the peripheral equipment to the processor 13, at the start of a predetermined section.
