Abstract

The machine-building industry frequently uses device control equipment so this paper aims to clearly present some case studies with the help of which we will highlight their measurement and control uncertainty. The case of limiting gauges will be analyzed using the relations for the delineation of the total limit control error ?LT by applying the generalized method. The general calculation relations and the unitary character of the methodology allow us to develop a mathematical model. The methodology and the general calculation relations facilitate the analysis of existing methods and means to find out to what extent they correspond to the real requirements, establishing the limits of their use from a technical and economic point of view. The specific weaknesses and limits of classical control equipment will be highlighted because they are important in the design, choice and determination of their use in control operations and technologies.
