基于叶轮的逆向工程及快速成形在实训教学中的应用

Based on the Impeller of the Reverse Engineering and Rapid Prototyping in the Application of Practice Teaching

本文以叶轮零件设计为例,通过叶轮的"结构分析→扫描→3D建模→3D打印"来研究探讨逆向工程在实训课程中的应用。实训内容包括四步:1.用3D扫描仪对叶轮的表面进行扫描,获得表面的点云数据;2.将点云数据导入三维建模软件Solidworks进行建模;3.对建立的模型进行优化,为3D打印做准备;4.将优化后的模型导入快速成形机的软件中,进行分层打印。

In this paper, the design of impeller parts is taken as an example to study the application of the reverse engineering in the training course through the ＂structural analysis → scanning →3D modeling → 3D printing＂ of the impeller. The training content includes four steps： 1. Scanning the surface of the impeller with the 3D scanner to obtain the point cloud data of the surface; 2. Import the point cloud data into the 3D modeling software Solidworks for modeling; 3. Make the model Optimization, for the preparation of 3D printing; 4 will be optimized after the model into the rapid prototyping machine software, the layered printing.
