Interference check device, interference check method, and machine tool having the interference check device

Abstract

An interference check device is provided which, when a plurality of moving means are provided for one moving direction of one movable body, can conduct interference check of the movable body easily. The interference check device of the present invention has a configuration that it is disposed in an apparatus provided one or a plurality of moving bodies which are capable of moving in a predetermined direction and moving means for moving the one or a plurality of moving bodies, and has a plurality of moving means for moving at least one of the moving bodies, and conducts interference check when the movable body moves, which comprises: an absolute movement amount calculating part 13 which synthesizes the movement amount of the movable body in the same direction by the plurality of moving means, thereby to determine the absolute movement amount in the direction; and an interference check part 12 which is provided in association with this absolute amount calculating part 13 and conducts the interference check from the absolute movement amount.
