Abstract: A numerical controller first creates a shortest path which does not interfere with an interfering object and shortens a movement distance from a start point to a cutting start position, and then, creates one or more alternative paths having a smaller number of break points than the shortest path when determining a movement path of a tool from the start point to the cutting start position. Then, each of a movement time along the shortest path and a movement time along the alternative path is calculated, and the alternative path having the shorter movement time than the shortest path is determined as the movement path.
