Research regarding reverse engineering for aircraft components

摘要

Reverse engineering is a useful technique used in manufacturing and design process of new components. In aerospace industry new components can be developed, based on existing components without technical Computer Aided Design (CAD) data, in order to reduce the development cycle of new products. This paper proposes a methodology wherein the CAD model of turbine blade can be build using computer aided reverse engineering technique utilising a 5 axis Coordinate Measuring Machine (CMM). The proposed methodology uses a scanning strategy by features, followed by a design methodology for 3D modelling of complex shapes.
