Integrated Inspection System for Digital Manufacturing

我们正处于第四次工业革命的阶段，通过连接机器，工件和系统，创建智能制造网络来智能地控制自己。该网络的核心需求是一个完全数据集成的数字化制造平台。在数字化制造系统中，一个有价值的高质量数据来源是检验过程。在各个生产阶段对产品进行检验，不仅可以调查产品的质量，还可以提供有关生产健康的知识。迫切需要新一代的检测系统来支持数字化制造系统的各个层面，其中网络和物理组件在不同的规模和水平上紧密集成为一个信息物理系统（CPS）。综合检测系统（IIS）的基础是在一个富有成效的NSERC发现研究项目中开发的，该项目为坐标计量的CPS提供了一个体系结构。将传统坐标计量中的点测量计划（PMP）、替代几何估计（SGE）和偏差区评估（DZE）三个网络任务的顺序执行成功地修正为IIS中的闭环任务。IIS中开发的新方法是提高可靠性和对抗坐标计量固有不确定性的高效解决方案。在典型的IIS中，PMP动态地利用DZE对几何偏差的估计来修正从测量表面捕获的数据点集。随着离散测点集合的变化，SGE对最优拟合几何的估计也会随之改变。此外，DZE的唯一输出不是基于其是否符合公差的零件接受或拒绝。相反，DZE通过从离散数据点构建蒙皮模型来产生制造表面的详细偏差区域。该计划的核心理念是“消除数字化制造系统中reach检验数据的浪费”，最终目标是“零缺陷生产”。具有上述特点，IIS是数字制造环境中合法检测系统的完美候选者，也是工业4.0实施的理想选择。上述集成检测系统是任何数字化制造系统都迫切需要的。这将对加拿大制造业的经济成果产生重大影响，并促进工业4.0的概念。因此，投资新的制造技术和相关的工作是预期的。该研究项目为加拿大未来的制造业发展提供了非常有益的知识和技能，它对培养高素质人才（HQP）成为加拿大未来数字制造、检验和数字计量行业的领导者有着直接的影响，并为加拿大社会的福利带来了成果。

We are at the stage of the fourth industrial revolution when by connecting machines, workpieces, and systems, smart manufacturing networks are created to control themselves intelligently. The core requirement in this network is a digital manufacturing platform with full data integration. A valuable source of high quality data in the digital manufacturing systems is the inspection process. Inspection of the product at various production stages not only investigate the product's quality, but also provides knowledge regarding the production health. The new generation of inspection systems is urgently needed to support various levels of digital manufacturing systems in which the cyber and the physical components are tightly integrated at various scales and levels as a Cyber-Physical System (CPS). The foundation of Integrated Inspection System (IIS) has been developed during a productive NSERC Discovery research program to provide an architecture for coordinate metrology's CPS. The sequential performance of three cyber tasks of Point Measurement Planning (PMP), Substitute Geometry Estimation (SGE), and Deviation Zone Evaluation (DZE) in traditional coordinate metrology was successfully revised to closed-loops of tasks in IIS. The developed novel methodologies in IIS are highly efficient solutions to improve reliability, and to combat the inherent uncertainties in coordinate metrology. In a typical IIS, an estimation of geometric deviations by DZE is dynamically utilized by PMP to revise the set of data-points captured from the measuring surfaces. As the set of the discrete measured points change, estimation of the optimum fitting geometry by SGE will be revised accordingly. Moreover, the only output of DZE is not the part acceptance or rejection based on its conformance to tolerances. Instead, the DZE produces a detailed deviation zone of the manufactured surface by constructing a skin model from the discrete data points. The core concept in this program is "to eliminate the waste of reach Inspection Data" in digital manufacturing systems with the ultimate objective of "Zero Defect Production". Having the above mentioned characteristics, IIS is a perfect candidate to be the legitimate inspection system in a digital manufacturing environment, and an ideal choice for Industry 4.0 implementation. The integrated inspection system as described above is an urgent need for any digital manufacturing system. This will have a significant impact on the economic outcome of the manufacturing industry in Canada and fosters Industry 4.0 concepts. Therefore, investments in new manufacturing technologies and related jobs are expected. This research program develops highly beneficial knowledge and skills for Canada's future Manufacturing, it has a direct impact on training of Highly Qualified Personnel (HQP) to be the leaders in Canada's future digital manufacturing, inspection, and digital metrology industries, and results in welfare of the Canadian Society.
