Summary:In a numerical control device (1) for controlling positions of each axis of a machine tool in accordance with a machining program (11), an instruction (12) dictated in the machining program (11) is analysed by an analysis unit (13) to obtain movement data (15) and a movement type (17), an acceleration/deceleration-data selection unit (18) selects acceleration/deceleration data (19) in accordance with the movement type (17), and an interpolation-acceleration/deceleration unit (16) performs interpolation upon a movement route dictated in the movement data (15), in accordance with a command speed, performs acceleration and deceleration in accordance with the acceleration/deceleration data (19), and generates a position command (21).
