In this work, the strengths and weaknesses of constructing CAD models from coordinate measuring machines (CMM) and laser scanned data are examined, through case studies, and shown to be the complement of one another. This justifies the development of a reverse engineering system that combines CMM and laser scanning data in efficiently accommodating a much wider range of applications. Such a system definition is contained herein for a DEA Mistral CMM and Hymarc Hyscan 45C laser scanner. In a combined approach, data collected using CMM and laser scanning must be transformed into a common coordinate system. This data set combination, or registration, is facilitated by digitizing prismatic datum artifacts along with the part. The dominant uncertainty in this process lies in determining the location and orientation of these artifacts, relative to the part, for each data set. A new approach was developed to control this uncertainty in the CMM sampling of manufactured primitives. Focusing on planes, a series of fractional factorial experiments were conducted.
