This work presents the development of measurement system and calibration procedure for calibration of step gauge, standard rings and standard plugs. The main goal of the work presented here is to develop a system for precise step gauge calibration, which will offer the Slovenian industry cheaper and easily available step gauge calibration. The target measurement uncertainty was chosen based on local and global market research and determined as U??(?(0,1 µm)?^2+?(0,5•?10?^(-6)•L)?^2 ). This goal was achieved by using advanced computer simulations for help with development and extensive automatization of the measurement procedure. We have also developed a procedure for calibration of standard rings and standard plugs using the same equipment. In this way, the cost of equipment which represents the majority of development cost can be spread between two measurement procedures. The first part of the work presents the used equipment and upgrades needed for the developed procedure. This is followed by a presentation of the development of the measurement procedure, with an emphasis on environmental control. Finally, the last part presents the analysis of measurement uncertainty for both procedures and verification of the determined measurement uncertainties.
