Abstract

Computed tomography for dimensional metrology has been introduced in quality control loop for about a decade. Due to the complex measurement-error cause system, usually no consistent uncertainty reporting has been made. Modular test parts have been developed and used to investigate some influence factors intrinsic to CT-based data and their effects on checking features of size. The experimental planning and the most significant findings are outlined and discussed in this paper.
