  • Patent number: 8328172
    Abstract: A CNC system including a travelling drive bar assembly for support of material to be processed. A CNC system including a cutting tool operates on a work piece in at least three axes, with a gantry across the machine that a carriage moves along and a tool that moves vertically on the carriage. A drive bar, oriented perpendicularly to the gantry and to a vertical axis, may travel to support and move the workpiece along its line of orientation. The drive bar may include an elongated structural member, two tracks mounted longitudinally to the elongated member on opposite sides of the elongated member, and a rack, adapted to accept a pinion to urge the drive bar to move, also mounted longitudinally to the elongated member. Guide wheels may receive the tracks to support and align the drive bar. Rollers may further support material that is mounted to the drive bar.

  • Patent number: 6982731
    Abstract: A method and apparatus for interactive generation and provision of custom cutting files for CNC robotic tools. A generic model for a particular product that a user wishes to make with a CNC tool is provided on a server remote from a client, with corresponding representational images available to the user. The user may input changes to the default representational images, and transmit the data corresponding to the final design parameters to a remote site, where a custom cutting file is generated. The user executes a purchase of the custom cutting file, which is then transmitted or otherwise provided to the user.

  • Patent number: 5297885
    Abstract: An edge joint particularly adapted for use in boat construction and furniture construction due to its high strength and aesthetically pleasing appearance due to the elimination of external structural reinforcements such as chine logs and hardened fillets. The high strength non-reinforced edge joint comprises two bilaminated plywood panels positioned together at an angle between about 60.degree.-170.degree.. Each panel defines a V-shaped groove along one side thereof so that one leg of each of the grooves is in contact with a corresponding leg of the other groove and the second legs of the grooves are spaced-apart so as to form an open cavity at the juncture of the panel. A cementitious material fills the cavity so as to form the edge joint as well as the protected outer corner thereof.
