摘    要:反求工程一般借助三坐标测量机或者三维扫描仪实现零件数字化,测量设备成本很高,限制了反求工程的应用。针对这一问题,利用数控机床较高精度行走的机构,添加专用在机测头,构成数字化测量设备;利用CAD草图模型驱动,研究了路径信息的基本表示方法、不同特征元素上测量点的分布形式、测量点的区分和归属原则以及测点路径信息的导出形式,开发专用在机反求软件,自动生成反求路径的测量程序。该方法减少了测量数据量,简化了反求过程,提供了一种低成本的反求工程新方法。

关 键 词:反求  在机测量  路径  模型  规划

Abstract:The reverse engineering general with coordinate measuring machine or 3D scanner realize the parts digital,and the measuring equipment is very expensive which limit the reverse engineering application.To solve this problem,this paper uses the higher precision walking mechanism of numerical control machine,adds the special online probe to compose a digital measuring equipment.It uses the CAD sketch model to drive,which researches the basic representation method of the path information,the distribution form of the measuring point in the different characteristic element,the distinction between the measuring point,the attribution rules and the derived form of the path information of the measuring point.It also includes the development of dedicated reverse soft and the automatic generation of the measuring program reverser path.This method provide a new low cost reverse engineering means which decrease measured data and simplify the reverse engineering.
Keywords:reverse engineering  online measuring  path  model  planning
