Research and Application of Surface Reconstructed Technology for the Autobody Panels Based on CopyCAD

摘要

Autobody panels are mostly the complex 3-D surfaces.To reconstruct their surfaces by reverse engineering of material object,has important practical significance to increase the capacity and level in developing for the whole types of vehicles in China.In this paper,three dimensional coordinate measuring machine(CMM) AERS of Italian Corporate COORD3 was used for data acquisition.The software system CopyCAD of UK companies DELCAM was applicated to process data.The data were imported to the software Pro/E of American company PTC,and the autobody panels' surfaces were reconstructed.Furthermore,through software CAXA of Beijing Beihang Haier company,the Numerical Control (NC) programs were generated.Thereby,the rapid reverse of parts were accomplished.
