Patent ID: 7036236

Claim:
A check standard for use in calibrating a multi-axis coordinate measuring machine, comprising: a body comprising a plurality of surfaces; one or more surfaces comprise a plurality of apertures configured to induce exercising a linear motion of an X axis and a Y axis during the calibration of said multi-axis coordinate measuring machine, requiring a dual axis motion during the calibration of said multi-axis coordinate measuring machine, testing a diameter measuring capability during the calibration of said multi-axis coordinate measuring machine, exercising the complete range of a tilt axis during the calibration of said multi-axis coordinate measuring machine, detecting a cyclic error of said tilt axis during the calibration of said multi-axis coordinate measuring machine, requiring simultaneous operation of said tilt axis and a rotary axis during the calibration of said multi-axis coordinate measuring machine, and diagnosing and detection of a non-orthogonality of a linear axis during the calibration of said multi-axis coordinate measuring machine; one or more surfaces comprise an origin of a coordinate system for said plurality of apertures; and one or more surfaces comprise a fixture capable of being received by said multi-axis coordinate measuring machine.
