Abstract

The paper describes a study concerning point by point scanning of complex surfaces using tactile CMMs. A four factors-two level full factorial experiment was carried out, involving measurements on a complex surface configuration item comprising a sphere, a cylinder and a cone, combined in a single assembly. An investigation on the source and effects of different uncertainty contributors during this complex surface measurement was carried out. The factors involved are machine, probe, and operator, as well as procedure, dependant. The results obtained from the experiments were analysed in terms of deviations from CAD model, repeatability, and measuring uncertainty. Statistical analysis and uncertainty budget are presented.
