An in-situ Inverse Projected-Fringe system for on-machine inspection of axisymmetric parts is developed. Parts considered for this study are specular with RMS surface roughness >1 μm and have large slopes with radii of about 50 mm. The in-situ system is developed based on the previously reported Inverse Projected-Fringe technique in order to determine the on-machine measurement repeatability and reproducibility for industrial applications. In order to measure the whole part, a stereo arrangement and a new data fusion technique are used to increase the field of view of the system. A measurement trace with the highest Signal to Noise Ratio (SNR) is selected to achieve the best accuracy. The repeatability and reproducibility tests of the system are reported. It is shown the in-situ Inverse Projected-Fringe system is capable of measuring the form deviation from a master-part with repeatability and reproducibility of ±1 to ±7 μm, equivalent to a dynamic range of one part in 25,000 to one part in 3,600, respectively for the areas with higher SNR to lower SNR. Simultaneously, the RMS surface roughness has been measured with an accuracy of ±1.2 μm or better.
