Application of CAD/CAM Technology in the Development and Lofting of Complex Sheet Metal Parts
For a development and lofting of complex sheet metal parts, the traditional work is hard and lack of accuracy. Using CAD/CAM to aid development and lofting needs neither lofting site nor mathematic models, but can achieve high quality and efficiency. The development and lofting of multi-tapered conical tube with 90º elbows as an example, the paper describes the methods of development and lofting of complex sheet metal parts based on CAD/CAM technology, such as drawing view of four sections of tapered conical tube with 90º elbow, drawing graphic model and developed view of frustum conical tube, checking the coordination situation of each section oblique cone tube model, and blanking programming using CAXA wire EDM V2 software.
