Abstract

Abstract 0 A method and apparatus are described for the automatic gauging of engineering components. The apparatus includes clamp means for holding a component to be gauged; probe means for scanning a surface of the component; drive means to provide relative motion between the component and the probe means in three mutually perpendicular axes; measuring transducer means associated with the drive means and the probe means to generate signals to measure the degree of movement between the component and the probe means; computer memory means for storing data relating to a reference profile having dimensions which it is desired to achieve; computer means for comparing signals generated by the measuring transducer means with the corresponding singals in the memory means; computer means for calculating the error between the stored data and signals generated by the measuring transducer means to stack the component to maximise desired coincidence between the dimensions of the reference profile and the actual component. The method and apparatus are described with reference to the gauging of components having aerofoils.
