Abstract: An apparatus and associated method for a frame that is configured to rotate a workpiece around an axis of rotation. The apparatus has a measurement device, and a known fixture that is supported by the frame. A processor is configured to execute stored computer instructions to initially-calibrate the measurement device to the axis of rotation, to employ the initially-calibrated measurement device to obtain an initial-calibration value of the known fixture, to store the initial-calibration value in a digital memory, to subsequently use the initially-calibrated measuring device to obtain an in-process automatic recalibration (IPAR) value of the known fixture, and to compare the IPAR value to the initial-calibration value to calculate a compensation value indicating positional error of the apparatus.
