Research into the engineering application of reverse engineering technology

Abstract Based on previous research on reverse engineering (RE) technology, the engineering application of RE is explored in this paper. The application environment of RE is built with coordinate measurement machine (CMM) and CAD/CAM software. Taking a core die of the inlet of a diesel engine as an example, this paper describes the processes of RE, from object digitization, CAD model reconstruction to NC machining. Measurement data are acquired by scanning the physical object using a three-dimensional CMM. Through processing of measurement data, the authors succeed in creating a CAD model of the die and machining the die, gaining a good result.
