This report describes the Automatic set-up equipment to shorten the machining preparation work for machining of large castings and forgings. The system mainly consists of three modules : the first one is the computer-aided three-dimensional shape measuring system which consists of 5-directional measuring machine installed with a newly developed non-contact distance sensor, and processors provided to transform the measured distance data to coordinates then also to construct netire mesh point data of the object workpiece. The distance sensor is based on an astronomical telescope typed optical system, equiped with laser tube and one dimensional CCD set horizontally on the optical axis. The second is to determine the relative position of the required shape into the workpiece, and the third one is to calculate the NC data for the scribing lines. The proposed software system accepts both the workpiece shape data from the developed measuring system and the geometric model of the required shape from the CAD system. Also it adjusts the position and orientation of the geometric model in the workpiece space, makes the stock removal uniform around the workpiece, and generates NC data for the sribe based on these models. Satisfactory results have been confirmed by some tests.

本报告介绍了自动装配设备，以缩短大型铸件和锻件机加工的机加工准备工作。该系统主要由三个模块组成：第一个是计算机辅助三维形状测量系统，该系统由安装有新开发的非接触式距离传感器的五向测量机和处理器组成，该处理器将测量的距离数据转换为坐标并构造目标工件的网格点数据。该距离传感器采用天文望远镜式光学系统，配备激光管和水平放置在光轴上的一维CCD。第二步是确定所需形状在工件中的相对位置，第三步是计算划线的NC数据。建议的软件系统接受工件形状数据从开发的测量系统和所需形状的几何模型从CAD系统。调整几何模型在工件空间中的位置和方向，使下料均匀分布在工件周围，并根据这些模型生成数控加工数据。通过一些测试证实了令人满意的结果。
