ABSTRACT:
An arrangement for providing universal movement of a machine tool is provided in which there are parallelogram linkages, one of which has a link which maintains parallelism with a worktable and is movable in any direction in a plane. A machine tool is carried by this link to perform an operation on a workpiece on the worktable. Two linear actuators converge from pivotal mountings on the worktable to the link. Selective extension and retraction of the actuators causes appropriate planar movement of the machine tool. A limit switch arrangement is provided by marking the movement of a portion of the mechanism on a plate as the mechanism is extended to its limits, cutting out the plate along the line marked, and positioning the actuating arm of a limit switch in the opening. Movement to the limits of the mechanism's travel will trip the switch and interrupt power to the actuators.
