Evaluation of metrology technologies for free form surfaces
Published online by Cambridge University Press: 26 September 2012
Abstract
This research work describes a novel approach for comparing different technologies forfree form surface metrology: computerized tomography (CT), photogrammetry and coordinatemeasuring machines (CMM). The comparison has the aim of providing relevant information forthe selection of metrology equipment when measuring free form components. Resultsdemonstrate that there is the imperative need to assess the uncertainty andreproducibility of CT and photogrammetry measurements by applying some calibrationprocedures taking into account some recommendations for work piece alignment. This articlealso deals with costs issues, required standards, and necessary additional informationwhen selecting inspection equipment.
