Improving CT quality control of a micro injection moulded part by multisensor data fusion

Acquiring holistic and accurate 3D measurements for industrial parts is highly demanded in the fields of quality control, process optimization and product development. The increasing complexity in the design and miniaturization make the task of holistic 3D data acquisition difficult. For the last few years, industrial computed tomography (CT) has emerged as a promising coordinate measuring technology, which enables integrated quality control of complex workpieces combining dimensional metrology and material defects analysis. In this study, the potential of CT is utilized for quality assessment of a micro molded part; in addition, data from confocal microscopy is used for enhancement of the CT result by data fusion.
