  • Method of centering in roundness measuring instrument and system therefor
    Patent number: 5359784
    Abstract: A centering system in a roundness measuring instrument comprises a computing section, a detecting device and a programming device. The computing section seeks an average circle of an article to be measured, a value of eccentricity and a direction of an angle of eccentricity in response to a displacement signal of a forward end element, sets an output signal of a detector so that the position of the detector at the time the measurement element is present on the arc of the average circle becomes zero, and further, calculates only a displacement value of the measurement element in a direction of an X-axis or a Y-axis to the value of eccentricity. The detecting device detects an angle of rotation of an X-Y table in a direction of an angle of eccentricity of the X-axis or the Y-axis.
