Fiducial calibration systems and methods for precisely and accurately
manufacturing a part from a workpiece, inspecting or measuring a part,
and/or assembling a plurality of manufactured parts including providing a
workpiece, wherein the workpiece and the associated processes are subject
to environmental and structural variations, and disposing a plurality of
datums on a surface of or within the workpiece. The systems and methods
also including calibrating the separation distance between each of the
plurality of datums to workpiece distance units and disposing the
workpiece in a machine, wherein the machine is subject to environmental
and structural variations. The systems and methods further including
calibrating a coordinate system of the machine to the workpiece distance
units, manufacturing the part from the workpiece, inspecting or measuring
the part, and/or assembling the plurality of manufactured parts utilizing
the calibrated machine, and intermittently recalibrating the machine to
the workpiece distance units.
