Abstract: In a numerical control device 1 which controls positions of respective axes of a machine tool according to a machining program 11, a command 12 instructed to the machining program 11 is analyzed by an analyzing unit 13, thereby obtaining movement data 15 and a movement type 17, an acceleration-deceleration data selection unit 18 selects acceleration-deceleration data 19 according to the movement type 17, and an interpolation and acceleration-deceleration unit 16 generates a position command 21 by performing an interpolation on a movement route, which is instructed to the movement data 15, according to a command speed and performing acceleration-deceleration according to the acceleration-deceleration data 19.
