Abstract

This research investigates the operator mental models during the control electrodischarge machining (EDM) and compares the results to tradition lathe control. The study required nine experienced tool makers to verbalize or `think aloud' as they created a mold cavity using an EDM. The results of this research showed that operators did transfer mental models from traditional manufacturing experience, but needed to develop significant knowledge specific to EDM. They also experienced difficulty visualizing and establishing cause-and-effect relationships between EDM process parameters. Operators exhibited aspects of discrete and continuous control behavior.
