摘　　要：针对复杂型面钣金件设计困难的问题,研究基于Geomagic的钣金件NURBS曲面重构技术。采用非接触式激光扫描系统获取钣金件的点云数据,利用Geomagic Studio软件完成钣金件的NURBS曲面重构,并利用Geomagic Qulify软件对重构的曲面进行误差检测分析。检测结果表明:钣金件的曲面重构精度满足设计要求,验证了基于Geomagic的钣金件曲面重构技术的可行性。In view of sheet metal parts in complex surface design and the problems we have formulated a folding technique for such parts NURBS curved surface.The parts dot-cloud data were got through a noncontact laser scanning system by Geomagic Studio software to have completed such parts NURBS surface reconstruction while utilizing GeomagicQulify software to carry out tolerance tests and analyses of the reconstructed surface.Results show that precision of the sheet-metal works can meet the design requirements,thus proving feasibility of the technique.
