基于Imageware和Pro/E的弧面凸轮逆向设计及NC仿真加工
|
摘要
逆向工程技术是现代产品设计的一种重要手段,是消化和吸收先进技术的一种新方法,是先进制造技术的主力。二维CAD模型重构是逆向工程中的关键步骤。利用学校现有的Laser-RE600Ⅲ型非接触式的三维激光扫描仪采集了弧面凸轮的几何数据,并详细介绍了数据采集过程。利用逆向软件Geomagic Studio进行数据后处理,同时将处理结果导入Pro/E中进行三维实体重建,并通过Geomagic Qualify软件对所做模型进行变形量检测分析,然后结合数控仿真软件Mastercam进行仿真加工,从而为复杂产品的数字化逆向工程设计提供了一种切实可行的方法。
Reverse engineering technology is an important means of modern product design.As a new method for absorbing the advanced technology,reverse engineering is the main means of the advanced technology.Three-dimensional CAD model reconstruction is the key step in reverse engineering.By the Laser-the RE600 III non-contact 3D laser scanner the data of the geometry of the arc cam is collected,and the process of the data acquisition is introduced in detail.Then the post processing of the data is carried out by Geomagic Studio,the result is imported in to the Pro/E and the three-dimensional solid model is reconstructing,and the deformation of the mold is detected and analyzed by the Geomagic Qualify software,and then the machining simulation is done by Mastercam,thereby,a practical method for reverse engineering of the digitization of the complex products is provided.
