To control the operation of an actuator in the minimum time and with a high efficiency for an operation of a short pitch. A numerical control method for controlling the operation of at least one actuator by a servo circuit having a certain characteristic. The numerical control method is characterized in that an eigen value ( beta ) by which an amount of movement up to an eigen acceleration and deceleration time (Tp) of the servo circuit becomes one-half of a target amount of movement ( DELTA theta ) which is input and a step signal of a value ( beta x DELTA theta ) obtained by multiplying this eigen value with the target amount of movement is input to the servo circuit, whereby the operation of the actuator during a time from at least the start of the operation to the eigen acceleration and deceleration time is controlled.
