1. A system, comprising:

  • a metrology device configured to measure, for a cycle of movement of an operating tool arm along a programmed path, metrology values for a workpiece associated with a manufacturing machine comprising the operating tool arm;

    an encoder configured to convert the metrology values into encoded metrology values comprising a format compatible with the manufacturing machine; and

    a computer component configured to record the encoded metrology values in association with coordinate values generated by the manufacturing machine during the cycle of movement, wherein the coordinate values represent respective positions or orientations of the operating tool arm over time for the cycle of movement,wherein the encoder is further configured to generate an index signal that increments periodically at a first frequency, wherein the first frequency is higher than a second frequency at which the coordinate values are generated.
