A numerical control device (4) includes a primary distribution pulse calculation unit (18) that calculates primary distribution pulses obtained by distributing individually a movement amount in a first movement direction included in a movement command of a work or a movement command of a tool and a movement amount in a second movement direction included in a movement command of the work or a movement command of the tool for each of predetermined calculation cycles, a secondary distribution pulse calculation unit (20) that calculates, for each of the first movement direction and the second movement direction, secondary distribution pulses obtained by distributing the primary distribution pulses of each of the predetermined calculation cycles, which have been calculated by the primary distribution pulse calculation unit (18), before and after corresponding calculation cycles within ranges of distribution sections across the corresponding calculation cycles and having an acceleration-deceleration time constant of the corresponding movement direction as a section width, and then accumulating the primary distribution pulses for each of the calculation cycles, and a drive control unit (22) that drives at least one of a tool moving device and a work moving device on the basis of the secondary distribution pulses calculated by the secondary distribution pulse calculation unit (20).
