In the industry of sintered automobile synchronizer hubs, as in many others, a fast on-line measurement system of the production is a very important tool for production and quality control, enabling among others: extended quality control to all the production, lower start-up times, improved knowledge of the process and influence of its parameters and database management of the information. In this paper we describe an on-line optical measuring system that is able to inspect 100% of the production, making special emphasis on how the resolution and accuracy of the measurement could be compromised by factors that are not related to the sensor itself, as well as how to correct them. The paper also describes how to validate such a system according to the ISO 5725 standard.
