Abstract Scope |
Hybrid manufacturing systems are an emerging technology hoping to emphasize the benefits, while mitigating the drawbacks, of both additive and subtractive processes in their typical, separate states. However, this also holds system operators accountable for smooth production in both processes. This is additionally challenging due to the knowledge gaps and lack of readily transferrable hybrid knowledge available. This research presents a case study identifying the cognitive load and knowledge gap impacts on operators across three hybrid manufacturing systems. Operators completed surveys consisting of a cognitive workload scale, factors contributing to cognitive load, and a part quality assessment. Operators self-reported skill, rule, and knowledge-based (SRK) errors contributing to process setbacks. Preliminary results show statistically significant changes in part quality and cognitive workload factors when reporting instances of SRK mistakes. This work provides a foundation towards improving hybrid systems workspace design by better understanding operator interaction with the system and the designer. |
