Patents by Inventor Todd W. Rudberg

Todd W. Rudberg has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20140081444
    Abstract: An integrated system for building a fiber composite part which includes an automatic fiber placement machine and a laser projector for verification of proper fiber placement. The CNC machine is controlled by a build file, with the laser projector being controlled by a part projection file. A sequencer, responsive to both the build and projection files, automatically controls the sequence of operation of the building of the part and the projection of the boundary information. A display shows the fiber placement information and allows the user to select a particular region of the fiber placement for verification of proper placement.

  • Publication number: 20140081428
    Abstract: The system includes a software program for locating a machine in a fixed reference coordinate (FRC) system for a manufacturing system, such as a fiber placement machine used in the construction of a composite part. The software system also locates a part in the FRC, and further includes locating an optical tool point in space by using laser information from known two positions to determine the position of the optical tool point.

  • Patent number: 6550118
    Abstract: The apparatus and method includes a spindle portion which holds a cutting tool. The drill is initially moved forwardly of a pressure foot portion of the apparatus. The pressure foot portion is then moved forwardly along with the spindle and drill to clamp the mechanical assembly. A thrust control arrangement produces a reduction of the thrust on the tool holder such that as the assembly is being clamped, the tool initially contacts the workpiece and then remains stationary while the pressure foot moves forward to complete clamp-up. The positions of the tip of the tool and the surface of the workpiece are recorded and compensation is then made to the apex position of the spindle stroke, using a previously determined reference position of the tool relative to the workpiece.

  • Patent number: 6242877
    Abstract: An apparatus for controlling operation of a processing machine has a computer preferably with a computer aided design program configurable to model a kinematic velocity profile of a point of interest on a machine to be controlled. A graphical user interface on the computer enables an operator to select desired velocity points for a motor drive controlling motion of the point on the machine. A curve fit is applied to the velocity points to realize a desired velocity profile for the motor drive and the point on the machine. The desired velocity profile is then integrated and scaled in order to obtain a scaled velocity profile that realizes an actual, or target displacement of the point as dictated by operation of the machine. By controlling operation of elements of a machine with velocity profiles, coordination of associated elements and points on the machine can be visualized by an operator selecting the velocity points for each drive of the machine. A method for implementing same is also disclosed.
