PROBLEM TO BE SOLVED: To provide a numerical control method for realizing accurate management of mechanical vibration (allowable speed) and improvement of processing efficiency. SOLUTION: The numerical control method comprises a command reading step for reading a command path and command speed of a range until the lapse of a specific time from a specific point or a specific area, or a range up to a specific distance from the specific point or specific area to determine allowable speed at the specific point or specific area on the command path in the case of controlling the movement of a movable part with two or more axes along the command path according to the command speed; a speed command generating step for generating a speed command of each axis of each time based on the command path and command speed; a frequency component computing step for computing components of a frequency band of each axis corresponding to mechanical vibration included in the temporary speed command of each axis of each time; and an allowable speed determining step for computing the allowable speed along the command path of the specific area from the ratio of root mean square of components of the frequency band of each axis to the reference value of components of a preset frequency band.
