A portal-type positioning device includes two parallel linear guides provided with integrated linear drives, which support a separate X-carriage in a manner that allows movement in the X-direction, as well as a cross beam which is connected to the two X-carriages and movably supports a carriage in a Y-direction that extends perpendicular to the X-direction, with the aid of an integrated linear drive. In addition, the positioning device has a tool holder, which is guided on the Y-carriage in a Z-direction and holds a tool for machining a workpiece situated in an X-Y plane, the tool being disposed next to the cross beam at an offset in the X-direction. A force frame disposed above the tool in the Z-direction transmits a process force acting on the tool to the carriages LX1, LX2 without deforming the cross beam by a torque. The process force is applied by an electromagnet which acts between the force frame and the tool holder.

A manufacturing work machine including a beam member arranged in an X-axis direction of an XY horizontal plane, both ends of the beam member being supported to be movable in the Y-axis direction; a Y-axis drive device provided on one drive side end section of the beam member, the Y-axis drive device being configured to move the beam member in the Y-axis direction; and an X-axis drive member configured to move a work head provided on the beam member in the X-axis direction, wherein the beam member is a tube with an internal hollow running through in the X-axis direction, and is formed such that a beam width in the Y-axis direction is uniform, and a height direction dimension becomes smaller from the drive side end section to an end section on another side.

The present disclosure is directed to a Friction Stir Welding device for welding one or more arcuate work pieces. The device including an arcuate boom, a friction stir welding head, and a saddle operatively coupling the welding head to the arcuate boom for moving the welding head with respect to the arcuate boom. The saddle may be coupled to the arcuate boom via a drive mechanism for moving the saddle, and the welding head that is coupled thereto, with respect to the arcuate boom. The welding head may also be provided with three degrees of freedom with respect to the arcuate boom so that the welding head can rotate, tilt and move linearly with respect to the arcuate boom.

A system which can reliably prevent a worker from being caught in a door which is provided on a work machine. The system comprises a work machine which has an operable door, a door drive part which makes the door operate, a door controller which controls the door drive part, a robot which is provided so that at least part can enter and retract from the inside of the work machine when opening the door, and an entry detection part which detects a possibility of a person entering a predetermined zone which includes a range of operation of the robot. The door controller changes a command value to the door drive part which determines the speed of movement of the door when the entry detection part detects that possibility to a second command value which makes the speed of movement decrease.

A fabrication system may generally comprise an x-y positioning assembly, a clamping head to receive an end effector, wherein the clamping head is coupled to the x-y positioning assembly, a z positioning assembly, a platform including a surface that is rigid and substantially planar, wherein the platform is coupled to the z positioning assembly, and a controller operably coupled to the x-y positioning assembly, end effector, z positioning assembly, and platform. Methods of using the fabrication system are also described.

A machine tool comprises a frame, which carries a fixed gantry for supporting at least one tool spindle. The gantry comprises a gantry recess, through which a working space is accessible. The one or more tool spindles on the gantry can each be moved vertically in a first direction and in a second direction orthogonal to the first direction. The machine tool further comprises a workpiece table with at least one location for supporting workpieces. The workpiece table is movable in translation in a third direction Y orthogonal to the first direction and the second direction. At least one tool magazine is associated with the at least one tool spindle tool spindle. Tools for tool changing can be fed through at least one magazine opening in the gantry. Tool changing between the one or more tool spindles and the at least one tool magazine takes place in a pick-up process.

A positioning device is adapted for positioning a tool at a setpoint position on a flat substrate in an X-Y plane, the tool exerting a process force in its axial direction perpendicularly onto the substrate. The tool includes a multicomponent force sensor to measure unwanted process-force components in the lateral direction. The setpoint position of the tool is correctable by the positioning device such that the lateral process-force components are minimized.

A portable rail system for mounting an engraving device includes rails and crossbar members that are precisely joined, and include height adjustment devices for incrementally adjusting the height of the rail system relative to a work surface or contact surface, thus making the portable rail system capable of being assembled and disassembled at a work site to enable the use of an engraving device, such as a CNC router engraving systems, in situ, or on-site, rather than in a workshop. The portable rail system enables the use of a CNC router device or other engraving device on vertical surfaces.
