  • Binary machine tool holder
    Patent number: 6749376
    Abstract: A tool holder having two distinct phases, a first phase in which the tool is held in an interference fit with sufficient mechanical interaction between the two for the tool to be rotated at high speed and perform its intended purpose on a workpiece, and a second phase in which the tool is sufficiently released from the interference fit to be rapidly removed from the holder (as by an automated apparatus).
    Type: Grant
    Filed: December 11, 2000
    Date of Patent: June 15, 2004
    Assignee: Command Tooling Systems, LLC
    Inventors: William R Keefe, Randolf N. Johnson, Christopher M. Lodermeier, Peter J. Ness, Bradley E. Rowell, Mark A. Shannon, John Niethammer
  • Apparatus and method to measure tapered or conical parts
    Patent number: 6421929
    Abstract: A tapered part measuring apparatus and method measures male and female tapered or conical parts. The apparatus and method use non-contact linear measurement technology for accurate and repeatable measurements, particularly of tapered parts with large deviations from their desired measurements. The tapered part suspends in non-contact position to the non-contact linear measurement probe on a true vertical axis to accurately assume the same position on replicate measurements.
