面向产品创新设计的逆向工程技术实验教学
|
摘要
在实验教学中加强对本科生创新能力的培养日益受到重视。逆向工程技术是实现在已有产品基础上进行快速创新设计的重要途径,因而提出了面向产品创新设计的逆向工程技术实验。首先应用关节臂测量机来获取实体模型的点云数据,再用逆向软件对点云数据进行从点阶段到多边形和曲面阶段的一系列处理生成CAD模型,最后通过概念设计并结合正向软件对已有模型进行改进,实现创新设计。以一款手机壳模型的创新设计为例对实验教学流程进行了说明。该实验不仅能让学生掌握逆向工程的流程,并在此基础上进行创新设计,对提高学生的创新意识和设计能力具有重要的促进作用。
In the experiment teaching,strengthening undergraduates innovation ability is attracting more and more attention. Reverse engineering technology is to realize the rapid innovative design on the basis of existing products,thus,an experiment of product innovation design based on reverse engineering technology is proposed. The first step of the experiment is to obtain point cloud data of the solid model by arm measuring machine,and then generate the CAD model with a series of transaction of point cloud data from point phase to polygon phase and to surface phase by reverse software. And at the end,through the concept design and combination with forward software,the existing model is improved for innovative design. An example of a shell model is given to illustrate the experimental teaching process. The purpose of this experiment is to enable students to master the application process of reverse engineering,and learn how to make innovative design,which plays an important role to improve the students ' innovation consciousness and design ability.
