一种仿形无基准薄壁缘全型面余量分析及加工方法

By using three-dimensional laser scanning technology and reverse reconstruction methods, we have achieved full surface allowance analysis and same-station common-datum machining of contour-following thin-walled edge structural parts without reference. This solves the problems of low accuracy and low efficiency in traditional methods and improves machining efficiency and accuracy.

Abstract

本发明公开了一种仿形无基准薄壁缘全型面余量分析及加工方法，突破了仿形无基准薄壁缘结构件加工技术壁垒。首先基于激光扫描技术对毛坯全型面扫描，同时完成毛坯模型逆向重建，通过重建的毛坯模型与设计模型拟合对毛坯进行全型面余量分析；基于余量分析结果进行产品快速找正后对内型面及工艺基准面进行加工，并以内型面及工艺基准面作为外型面加工基准，实现内、外型面、连接孔以及外形轮廓同工位共基准加工。本发明实现了无基准仿形结构件全型面余量的快速分析以及多工序加工基准传递，解决了现有技术中产品检测及找正时间长、加工效率低、尺寸精度不足及表面质量差等问题，在陶瓷基机械加工领域具有广泛的应用前景。
