Application of Axiomatic Design for the Development of Robotic Semi- and Fully Automated Assembly Processes: Two Case Studies

Higher safety levels for workers, boosted productivity, and improved ergonomics at a reduced operating cost are some of the main benefits of automation. This paper presents how Axiomatic Design methodology can be successfully used to develop both semi- and fully automated robotic workstations. Specifically, two case studies are presented. The first concerns the semi-automation of a wire harness assembly process. The re-design of the assembly panels and the introduction of a collaborative robot contributed to reducing the operator's biomechanical overload and the cycle time. The second case study concerns the automation of three manual assemblies of shower enclosure components. After undertaking a detailed cost/benefits analysis, it was decided to design a single robotic cell where all three products can be assembled. This decision led to an improved investment to the savings ratio and operator's ergonomics. In both case studies, the Axiomatic Design approach was used to compare the different technologies available and to determine the best solutions to meet the operator's wellbeing and business needs.
