Abstract: Combining multiple sensors on CMMs (Coordinate Measuring
Machines) is useful to fulfill the increasing requirements on both complexity and accuracy in
dimensional metrology. Yet, the methodology to plan measurement strategies for systems combining
different types of sensors is still a major challenge. Such planning is commonly done in an interactive
way. This paper presents a methodology which can create inspection plans automatically for CMM
inspection combining a touch trigger probe and a laser scanner. The inspection features are specified
based on the extracted geometry features and the associated PMI (Product and Manufacturing
Information) items from a CAD model. A knowledge based sensor selection method is applied to
choose the suited sensor for each inspection feature. For touch trigger measurements, the sampling
strategy considers the measurement uncertainty calculated by simulation. A geometry-guide method is
developed for collision-free
probing path generation. For laser scan measurements, the required view angles and positions of the
laser scanner are determined iteratively, based on which the scan path is generated automatically. The
proposed methodology is tested for several cases and validated by measurement experiments. The
methodology provides suited planning results and can be used for automated dimensional inspection,
i.e. Computer Aided Quality Control (CAQC).
