Réalisation de cales étalons de longueur en céramique

Abstract

The gauge block is a standard length with opposing flat and parallel surfaces which is widely used in industry. It is made of hard wear-resistant material (treated steel, carbide, quartz, ceramic, etc.), with ultra-precision machines under well-defined working conditions. Our subject is an industrial project consisting in studying and producing a series of gauge blocks through a practical internship at the Institute of Optics and Precision Mechanics and a small external company, ceramic art workshop. For this we have tried to find a material that gives the desired qualities given the availability of means and manufacturing. To classify these gauge blocks according to the international standard, we performed a calibration in the metrology laboratory of the Institute of Optics and Precision Mechanics. After that, we processed the calibration results to get the final result.
