Abstract
The first article inspection of cast turbine blades is on the critical path of a new aeroengine. The current methods used are open to automation using CMM's and non-contact gauges to reduce lead times. A graphics system is discussed which allows modelling of the blade and Computer-Aided Part Programming of CMM's to produce a Neutral Data File for post processing. Once measured on the CMM the actual blade is modelled and bestfitted to the design intent. This allows subsequent error analysis to be carried out. Such a system is essential to make sense of large amounts of co-ordinate data and storage of dimensional variation at stages in the manufacturing process.
