The application of X-ray stereo metrology to investment casting dimensional control
- GE Corporate Research and Development Center, Schenectady, NY (United States)
High precision investment casting designs, particularly of jet engine and turbine components, are rapidly evolving in complexity. In order to reduce the development cycle for a new design it is necessary to monitor and control the critical dimensions of the casting and associated cores and molds. In addition, detailed knowledge of the casting geometry is necessary to plan, for example, the drilling of cooling holes during airfoil manufacturing. A new approach to dimensional control of casting manufacturing operations based on X-ray metrology will be described. Precise measurements of casting dimensions and hole geometry can be achieved by a combination of conventional X-ray CT algorithms and new algorithms for radiographic stereo. Together these provide both completeness of part description as well as high throughput for production monitoring. This paper will describe a system called the QUIC (QUality Investment Casting) system being developed to implement these algorithms.
