Abstract

This paper evaluates occupational health and safety (OHS) risks in the electrical discharge machining (EDM) process and examines how different operational scenarios affect these risks. Building on a previous study, four scenarios were tested to determine the most efficient setup in terms of machining time, material removal rate (MRR), and electrode wear rate (EWR), and the most favourable one was identified. The methodology includes mapping the EDM process flow, linking activities to potential risks, assessing probability and severity using a risk matrix, and proposing preventive measures to reduce hazards. The study highlights the scenario that best balances efficiency and safety, demonstrating that proper risk management can optimize employee well-being.
