Abstract
A numerical controller has a test mode of a machining program, sets, for each axis, a neighboring distance from a movement prohibition boundary of a tool or a workpiece, and temporarily stops an axis movement at a boundary of a near region thereof. A movable distance in a direction approaching the movement prohibition boundary is obtained for each axis such that the movable distance is less than a distance to the movement prohibition boundary. Further, if an axis exceeding the movable distance is present, an axis movement is stopped by restricting a movement distance within a range not exceeding the movable distance.
