The present invention discloses a method and apparatus for distributing command pulses to a numerically controlled machine which is provided with a first and a second control axis having different resolution. The first control axis has a smaller resolution than the second control axis. The numerical datum for each control axis, based on the smaller resolution are given to the pulse distributing circuit. When the command pulse obtained by the pulse distributing operation is supplied to the first control axis, the movable part of the machine is displaced by an amount corresponding to the smaller resolution. At this time, the distributing point is also moved by the same amount in the first axis direction. When the command pulse is supplied to the second control axis, the movable part of the machine is displaced by an amount which is a multiple of the smaller resolution by the ratio of the resolutions of the two control axes, and the distributing point is also moved by the same amount in the second axis direction.
