This research aims to construct the integrated three dimensional coordinate measuring system that measures dimensions and geometrical quantities (form, orientation and location) of the work with 3DCMM (three dimensional coordinate measuring machine).There have been many researches on the automated systems that manage the design and machining process by CAD/CAM method. So at present these systems are at the stage of practical usefulness. But the inspection process has not been integrated with the design and machining process yet, because the inconsistency between the information used in inspection process (for example, that about form, tolerance of products and machining process) and the information used in CAD/CAM system exists, and the measuring process itself has unresolved problems. Therefore CAG (Computer Aided Gauging) corresponding to CAD/CAM must be established in the inspection process.In the automatization and the integration of measurement with 3DCMM, 1. method to estimate th … More e form, 2. automatization of the measuring process planning, 3. improvement of probe, 4. method of recognize the orientation and the location of the measured object have been researched. Then the following results was obtained.1. The method suited to the automated measurement of the three dimensional form is offered. This method estimates the form by statistically processing many points measured by 3DCMM.2. The system making decision, which is necessary to the automated measurement with 3DCMM, has been constructed.3. As the result of the experiment on the distance measurement by the external optical feed back effect on semiconductor injection laser properties, this effect can be applied to the non-contact probe for 3DCMM.4. The method to recognize the orientation and the location of the measured object according to its design-data is offered.In future we will research on the generalization of the measuring process planning system, executing system and form estimation system and the method of probe control.

本研究的目的是利用三维坐标测量机(3DCMM)构建测量零件尺寸和几何参数(形状、方向和位置)的一体化三维坐标测量系统，目前已有大量的CAD/CAM方法管理设计加工过程的自动化系统的研究。因此，目前这些系统还处于实用阶段。但由于检测过程中使用的信息(如形状、产品公差和加工工艺等)与CAD/CAM系统中使用的信息存在不一致，测量过程本身也存在问题，因此检测过程还没有与设计和加工过程集成。因此，在检测过程中必须建立与计算机辅助测量相对应的计算机辅助测量系统。在测量与三坐标测量机的自动化和集成化中，1.…的估算方法2.测量过程规划的自动化；3.测头的改进；4.被测物体方位和位置的识别方法。然后得到了以下结果：1.提出了一种适合于三维形状自动测量的方法。该方法通过对3DCMM测量的多个点进行统计处理来估计形状。构建了实现三坐标测量机自动化测量所必需的决策系统。作为外部光反馈效应对半导体注入激光器性能影响的测距实验结果，该效应可应用于三维坐标测量机的非接触式测头。提出了根据被测对象的设计数据识别被测对象的方位和位置的方法，并对测量工艺规划系统、执行系统、形状评价系统的通用化和测头控制方法进行了研究。较少
