The present invention provides an energy saving type numerical control device which adjusts a variable speed of a transfer shaft and a variable speed of spindle rotation to minimize consumption power of a machine tool. According to the present invention, the numerical control device comprises: a processing program unit which issues a command about at least one among a location, a speed, and a variable speed for driving a main shaft motor and a transfer motor, according to a processing cycle; and a time constant calculating unit which sets a time constant of each command that a cycle includes in connection with the processing program unit. |
