<p>This invention relates to a numeric controller which effects movement of a next block without interrupting the movement of a work, etc, even when a skip signal is inputted, and thus reduces a cycle time. First, skip signal detection means (1b), in response to a skip signal SS outputted from detection means (2), stores a present position (1aa) of a work (4) in memory means (1a), and outputs a skip completion signal AS. Next, acceleration/deceleration distribution means (1c) effects pulse interpolation of a present block, and outputs a distribution completion signal ES after the movement is completed. Receiving this skip completion signal AS, pre-treatment distribution means (1d) determines a moving distance of the next block from the present position (1aa) of the work (4), and conducts pre-treatment of the next block of the machining program (1ac). The means (1d) receives the distribution completion signal ES outputted from the acceleration/deceleration distribution means (1c), outputs the interpolation pulse IP2, and moves the work (4) without an interruption.</p> |
