This report focuses on providing a foundation for further investigation into the inspection of fixed CURVIC coupling contact pattern by way of modern metrology techniques. Previous bodies of research have utilized coordinate measuring machines (CMMs) to analyze specific features of these couplings, but not the interaction between mating couplings at the areas of contact. It is hoped that this report will provide a basis for further research to improve the efficiency and reduce the ambiguity inherent in the current contact pattern inspection technique. This report contains a comparison between the results of traditional contact pattern inspection and those obtained by CMM. Test couplings were designed, manufactured, and inspected at California Polytechnic State University, San Luis Obispo (Cal Poly). Methods used show a correspondence between the calculated distance between regressed surfaces and the amount of transfer seen from tooth to tooth, but are unable to provide the resolution necessary to make any determinations of what that contact may look like across one tooth surface.
