The performance evaluation for dimensional measurements with industrial computed tomography systems

In modern intelligent living, X-ray computed tomography (CT) exhibit the great potential in industry for non-destructive dimensional quality control purposes, which serving a range of monitoring and management, from chips, integrated circuits, batteries, and automotive components. In this paper, a special standard sample was designed and manufactured to test critical dimensional characteristics on different CT systems. Additionally, a sequential participation scheme, together with detailed measurement procedures and reporting instructions, has been proposed to evaluate measurement uncertainty and determine metrological performances of CT systems. Finally, a series of experimental tests were carried out to demonstrate dimensional measurement errors of CT systems. Those results have been proven to be amenable for practical purposes through many tests so that it might be applicable to achieve accuracy and traceability issues of CT systems in industrial intelligent production line.
