摩托车车体模具的数字化设计与制造

Digital Design and Manufacture of Die for Motorcycle Body

开发了摩托车车体模具数字化设计与制造流程。利用反求设计和曲面重构理论 ,提出了车体、弯管件和复杂型面的测量规划 ,结合三坐标与常规测量数据建立了车体CAD模型和弯管弯曲模具CAD/CAM模型 ,实现了摩托车车体模具的数字化设计与制造 ,为复杂焊接组合件模具的反求设计与制造提供了一种切实可行的方法。

A digital design and manufacture process of die for motorcycle body is developed. Inspection planning for motorcycle body, bending tube and complicated profile is presented based on reverse engineering and surface reconstruction technique. The CAD model for motorcycle body and CAD/CAM models for bending tube are introduced with utilizing the inspection data. Digital design and manufacture of die for motorcycle body is then implemented to supply a practical method of reverse design and manufacture of the die for complex welding components.
