This article presents influence of measuring probes on a dynamically measured part made from automotive aluminium alloy. Dynamic measuring (during rotation or translation) is limited not only by scanning rate of measuring sensors and processing devices, but also by physical and metrological attributes of measuring probes, which are in direct contact with the measured part. Current trend in automotive industry is to reduce weight, production costs and input materials costs, while achieving higher precision of manufactured parts. Due to these reasons, aluminium alloys with high volume of silicon are used more often than before. However, dynamic measuring of such parts presents difficulty, as the probes and measured parts interact. This interaction was the subject of the research made by Mesing Ltd. in cooperation with University of Technology Brno. The unexpected absence of adhesive wear in cases of Al2O3 and WC tips make them the most suitable materials for aluminium alloy measuring.
