process configuration

The increasing shortage of IT specialists requires lower-skilled employees to be empowered to perform tasks that previously required the involvement of experts. Industry 4.0’s emerging technologies for human-technology interaction and for the digital twin allow the design of intuitive user interfaces, system-independent communication interfaces, and user-specific assistance functionalities to meet this challenge. This paper presents a framework for configuring and monitoring of process flows for different production and logistics systems. By reviewing existing programming approaches, the paper derives requirements for the framework, describes its general architecture and the technical realization of the modular interaction interface. A prototypical implementation validates the presented concept on the example of a cellular conveyor system and a collaborative robot system.

Exact planning and configuration of process chains contributes significantly to manufacturing excellence in micro manufacturing. In this type of manufacturing, production must adhere to very low tolerances. Furthermore, a multitude of manufacturing processes is available in micro manufacturing whereas some processes are better suited than others for given tasks. The methodology “Micro Process Planning and Analysis” (µ-ProPlAn), which is described in this article, provides suitable means for planning and configuration of such process chains with the necessary level of detail. To reduce the manual workload in comparing alternative process chains, this article proposes an extension, which enables an automatic selection of alternative processes based on a geometry oriented annotation of the µ-ProPlAn process models.
