工业环境中数字化道路上的最大障碍之一是缺乏通信标准。这在几个领域交汇的地方尤为明显。在这种情况下，传统机床、机器人和计算机视觉必须通过一个共同的接口进行交互。我们提出了一种基于OPC UA的结构，它统一了人类操作员的编程过程，无论任务最终是由机器人还是机床执行。我们的想法是使用OPC UA技术来制造由常见标准几何特征（如孔或凹穴）组成的组件。我们的方法可以将所需的制造参数直接从CAD模型转换为OPC UA技能，而不是使用CAM。因此，有必要调查合适的CAD接口，以及使自主实施的过程中的制造系统。通过这种方法，可以推导出制造过程的OPC UA伴随规范的定义。该概念的实施进行了一个灵活的机器人单元。
One of the biggest obstacles on the path to digitalization in an industrial environment is the lack of communication standards. This is particularly evident where several domains meet. In this case, conventional machine tools, robotics and computer vision have to interact over a common interface. We propose a structure based on OPC UA, which unifies the procedure of programming for the human operator, regardless of whether the task is performed by a robot or a machine tool in the end. The idea is to use OPC UA skills for the manufacturing of components, that consist of common standard geometric features such as holes or pockets. Our approach enables the translation of required manufacturing parameters directly from a CAD model to OPC UA skills instead of using CAM. Therefore, it is necessary to investigate suitable CAD interfaces as well as enabling an autonomous implementation of the process on a manufacturing system. From this approach, the definition of an OPC UA Companion Specification for manufacturing processes could be derived. The implementation of the concept is carried out on a flexible robot cell.
