  • Patent number: 5529441
    Abstract: A system and method for optimizing drill coordinates in a multi-layer printed circuit board, to correct for interlayer shift during lamination. A set of test patterns, in the form of a cross formed by two orthogonal conductor lines, are defined at each corner of each layer in the same nominal location. Under ideal conditions, the test patterns of the layers in each corner are lined up one above the other, without any offset. A counter sinking tool is used to cut a conical bore in the location of the test patterns, so that every test pattern cross is interrupted in four places, generating a four segment pattern in each layer. A high resolution camera is placed above the countersunk bore to form a single image of the exposed segment edges of all the test patterns exposed by the bore. The image is analyzed to determine the amount of shift of each layer. If all patterns are perfectly concentric, all crosses are perfectly aligned.

    Abstract: A machine for duplicating musical reeds comprises a force sensor supporting a drill bit, which acts both as a measuring contact, when stationary, or as a tool for removing material from the surface of a reed, when rotated. A flexural resistance map of a master reed, having desirable musical characteristics, is made initially, by moving the drill bit toward the reed surface a predetermined distance after initial contact is made, and storing the resultant reaction force in a computer. The master reed is then replaced with a new reed, at least as stiff as the master, and the process is repeated, comparing the readings with corresponding readings for the master. Where the reed is too stiff, material is removed from its surface by the drill bit; this is repeated over the entire reed surface, until the flexural resistance map of the new reed matches that of the master.

    Abstract: In a method and machine for balancing centering a workpiece, such as a crankshaft, to be machined only at certain portions and in which the workpiece is transversely displaced with respect to an axis of rotation so as to minimize any unbalance and is subsequently cut to length, after which centering bores are formed in the opposite end faces of the workpiece to define the axis of rotation, the final balancing after the finishing machining of the workpiece is optimized by pre-balancing the workpiece in a manner which takes into account only the unbalance of those workpiece portions which will not be machined to determine the extent and direction of the transverse displacement.

  • Patent number: 4860499
    Abstract: A spark plug grinding machine is equipped with force sensors to measure grinding forces and other forces attendant to a grinding operation. Ceramic spark plug insulators are carried by spindles on a Ferris wheel into a grinding station. A control wheel engages and spins each part as a grinding wheel grinds the surface of the insulator. A three axis transducer on one of the spindles measures force components along the axis of the spindle, parallel to a tangent of the grinding wheel and in a radial direction. A torque sensor on the control wheel measures the torque as the wheel rotates each insulator. Either or both of the sensors may be used. They are coupled through slip rings to a recorder.

  • Patent number: 4812090
    Abstract: The present invention relates to a method and apparatus for adjusting the weight of workpiece by twice machining a weight-adjustment portion formed on the workpiece. In the present invention, the same cutting tool is used for machining the weight-adjustment portion and the feeding position for the second machining of the weight-adjustment portion is determined in response to the weight of the workpiece after the first machining. According to the present invention, even if the tips of the cutting tool should wear because of prolonged machining operations and, as a result, the amount of the first machining is insufficient, the said insufficiency is compensated for by the second machining.

  • Patent number: 4629378
    Abstract: An integrated factory system affords precision machining and inspection of aircraft turbine blades, as well as other metal parts having two generally opposite principal surfaces. It uses only two stages of chucking by the meltable matrix method. After embedding one of the surfaces in the first chuck, which positions the blank relative to a plane of reference, the other surface is machined and inspected according to programs relative to that plane. Without release from the first chuck, the part is transferred to a second chuck for embedding the machined principal surface relative to a second parallel plane of reference a precise distance from that of the first chuck. Machining and inspection is now completed relative to this second plane of reference. Improved matrix chucks are provided, as well as new chucking apparatus which establishes the planes of reference.

  • Patent number: 4626147
    Abstract: A method of and apparatus for balancing a rotary body is disclosed. The apparatus includes an unbalance detection unit which rotates the body in first and second spaced bearings, the location of the first and second bearings defining first and second bearing planes, respectively. The forces developed by rotation of the body are sensed at the first and second bearing planes and the forces about the first bearing plane are summed to determine the weight and angular location of a mass compensation which, if effected, would substantially statically balance the body. An iterative technique is utilized which determines the axial location of the mass to be removed or added which would reduce to a minimum the dynamic unbalance of the body. The body is then passed to an unbalance correction unit which removes or adds the mass at the determined angular and axial locations to minimize the static and dynamic unbalances.
