<p>This invention relates to a numerical controller (CNC) which checks the machining program by operating a manual operation key or the like. A direction signal which determines the direction of a distribution pulse and a speed signal which determines a distribution speed are inputted from an operation board (4). Pulse distribution means (5) synchronizes the machining program processed by pre-processing means (3) with the speed signal, distributes the pulses by forward feed when the direction signal is positive and distributes them by reverse feed when the direction signal is negative. In this manner, processing of the machining program becomes easy.</p> |
