  • Patent number: 6993821
    Abstract: A manufacturing cell having a plurality of work stations, where at least one of the work station comprises a metalworking machine, and where at least one metalworking machine is provided with a modular tooling apparatus. The modular tooling apparatus consists of a base having one or more attachment surfaces, and one or more inserts that can be inserted semi-permanently to the attachment surfaces. The attachment surface is typically a pocket in the surface of the base. The insert has a workpiece support feature that can support and/or secure the workpiece into the proper position and orientation for machining. The base, pockets and inserts are configured to provide a characteristic location and orientation for the workpiece relative to the base, and to the metalworking machine.

  • Patent number: 5836575
    Abstract: A wafer stand for facilitating the inspection, testing, and handling of large-diameter silicon wafers, such as those having a diameter of 8 inches (200 mm), during semiconductor processing and assembly. The stand consists of a lower plate or pedestal, a plurality of adjustable legs mounted thereon, and an upper plate mounted on the upper end of the legs. The top plate has an access aperture of a diameter coinciding approximately with that of the wafer, and can be adjusted such that the attitude and/or height of the upper plate in relation to the pedestal can be varied. In one embodiment, the front leg of the stand may be removed to provide better access to the bottom of the wafer. The upper plate is also provided with a pair of parallel tracks into which a wafer mounting frame can be slid to position the wafer over the access aperture. The wafer stand is constructed so as to permit its temporary mounting to a workbench or table, yet is fully transportable by one person.

  • Patent number: 5621965
    Abstract: In very high speed adiabatic face milling machines whose operation provides a highly efficient machining process suitable for production manufacturing conditions, it is essential that appropriate fixturing is utilized to position and support the workpiece in order to induce added rigidity to the workpiece while reliably clamping and dampening each workpiece to enable machining to withstand small flatness tolerances. Accordingly, primary rests are spaced apart relative to one another to ensure that a stable platform is provided for each workpiece. Force inducement devices are strategically positioned along peripheral edges of the workpiece to selectively deflect the workpiece and thereby significantly add rigidity to the workpiece to better withstand the cutting forces associated with the milling operation.

  • Patent number: 4565358
    Abstract: A plate positioning apparatus which determines the position of a plate workpiece for a processing machine by an aligning member which moves in the X-axis direction and an aligning member which moves in the Y-axis direction. The Y-axis aligning member is provided with a movable retainer which retracts toward the Y-axis side when it comes in contact with the X-axis side aligning member and comprises a base part and an extension member which is remountable on the base part. The aligning member for the X-axis is provided on its upper surface with at least one aligning bar which contacts the plate workpiece. The aligning members for both directions of X and Y axes are adapted to be guided by the base frame and their moving strokes are controlled by position detecting switches provided in the base frame, the base frame being closed at its upper side by the cover plate. The respective slits along which the aligning members move are covered with respective movable dust-proof belts.

  • Patent number: 4230310
    Abstract: Holding members for engaging the corners of base plates of nail plates while wooden beams are force down on the upwardly projecting nails to form a truss are made of resilient plastics material of about the same thickness as the base plate and provided with a self-adhesive surface for fixing them relatively to a preparation table. Each holding member is formed at one side so as to lie against the edge of the base plate at at least two points respectively on both sides of the the associated corner. A comparatively thin supporting layer of harder material may be secured on the upper face or between or on both faces of the resilient material.
