Abstract: A tip 14 is rotatably attached to a tip holder 10. The tip holder 10 is made into a cylindrical shape and its end has an installation part 16. An opening is arranged at a holder joint. The tip holder 10 is attracted by a magnet for attachment so that detaching and attaching can be performed easily. Tip offset data is recorded as a 2-dimensional code 17 on the surface of the tip holder 10. When replacing the tip holder, the offset data is read out and inputted to a scribe device, thereby canceling the offset. This eliminates the operation required for correction when attaching/detaching the tip holder and enables easy tip replacement during a short time of device stop.

Abstract: An automatically programmable tilting mechanism for holding a scribe tool at varying angles using an aerostatic bearing. The air bearing secures the scribe tool about its longitudinal shank and generally allows for free axial movement while the tool holding structure prevents rotation of the scribe tool, thus providing extremely fine compliance and force application of the scribe tool point against the substrate. During a scribing process, the tilting mechanism regularly adjusts the angle of the scribe tool relative to the substrate so that a fresh cutting edge is always being employed in the scribing process.

Abstract: A tool for scribing a longitudinal groove on an elongate cylindrical rod suitable for implanting as a prosthetic in a living being supports the rod in a linear groove on a bed of a frame of the tool. A track is mounted on the frame and runs parallel to the groove. A carrier mounted on the track can slide on the track in constant spaced relation to and along the groove. A scribe mounted on the carrier extends toward the groove to contact a rod in the predetermined position. A preferred version of the tool has a clamp mounted on the bed for clamping the rod in the predetermined position. Additional features allow for precise angular positioning of the rod and for scribing a dashed line on the rod. In use, the tool operator places the rod in the predetermined position in the groove. The scribe is then pressed into contact with the rod. While the scribe is in pressed contact with the rod, the operator slides the carrier along the track.

Abstract: A holder 20 is rotatably connected to a body 10. A scribe tool 30 is attached to one end of the holder 20. A plate spring 16 is fixed to the body 10, and a receiving plate 26 is fixed to the holder 20. A piezo-actuator 40 is interposed between the plate spring 16 and the receiving plate 26. One end of a plate spring 50 having a small spring constant is fixed to the holder 20. The body 10 is provided with an adjustment screw 60. When a lower end part 65 of the adjustment screw 60 is protruded, the lower end part 65 presses the plate spring 50 for flexure, thereby generating a resilient force to the plate spring 50. By this, a rotational force is given to the holder 20 and thus a pressing load directing toward a workpiece is given to the scribe tool 30.

Abstract: A body (10) movably supports a holder (20) for movement in a vertical direction. A piezo actuator (40) is sandwiched between the body (10) and the holder (20). Vertical vibrations of the piezo actuator (40) are transmitted to a cutter (30) attached to a lower end portion of the holder (20), so that a scribe line is formed on a workpiece (100). The holder (20) is supported by a resilient member and a slide support portion (60) with the piezo actuator (40) placed therebetween. The resilient member includes a plate spring (61) and a ball (62) made of resilient material. The resilient member resiliently supports the holder (20) in the vibrating directions.

Abstract: A jig apparatus that allows one to cut arches in a work piece quickly and efficiently. It is comprised of a bar that has sliding adjustable clamps that secure a cable which go around pulleys on a router or other cutting device that when the cable is pulled taut, creates a path for the router or other cutting device to follow while it cuts thus cutting an arch into the work piece. Prior to this apparatus one would have to cut this arch with a template which had been previously tooled. This jig apparatus creates a template and cut all in one step.
