摘　　要：为实现检测过程自动化从而提升检测效率,针对航空结构件,提出一种坐标测量机检测轨迹的自动规划方法,开发了一套检测轨迹自动规划系统。依据测量点的法矢及测量机的摆角分度特性计算测头对应的位姿;以航空结构件的几何特征为驱动,对检测轨迹进行规划;基于VERICUT对检测轨迹进行仿真,避免测量过程的干涉碰撞;构建检测轨迹与DMIS语句的映射关系模型,实现测量程序的自动生成。应用验证表明,该系统能直接依据三维模型进行检测轨迹的规划,减少了测量过程的人工干预,检测效率较传统检测模式提升22%-34.6%。To enhance the efficiency and automation in inspection,a method of inspection path planning for coordinate measuring machines is develop and applied in this study.At first,the position and orientation of the probe was calculated based on the measurement point normal and measuring machine indexing characteristic.After that,a geometry-based inspection process was carried out.Then,in order to avoid the interference in the process,the process was simulated in VERICUT.Finally,by constructing the mapping model between inspection paths and the DMIS,the inspection program was automatic generated.The application results show that,by applying the proposed method,the inspection path is planned based on the three-dimensional model directly.And the inspection efficiency increase of 22% - 34.6% than the traditional way with manual intervention.
