ABSTRACT:
An automatic sheet metal machining center has a frame, a work table attached immobile to it, a first carriage movable with regard to the frame, a second carriage attached to the first carriage and movable in a direction perpendicular to the path of the first carriage, and a stop pin in the frame. The stop pin is immobile in the directions of the paths of the carriages and is movable to upper and lower positions in a direction perpendicular to the plane of the work table. The position of a work piece, after having been placed on the work table, is determined in relation to the direction of the path of the second carriage, which has clamps for grasping the workpiece. The clamps are movable in the direction of the path of the second carriage and lockable thereto. According to a preprepared program, the respective positions of the clamps, with regard to the second carriage for grasping the workpiece, are automatically recognized and locked onto the second carriage with the aid of the stop pin.
