What occurs during the Off Time in an EDM cycle?

During the Off Time in an Electrical Discharge Machining (EDM) cycle, the metal is cooled and the debris created during the machining process is flushed away. This phase is critical because it allows for the dissipation of heat that has built up during the On Time, when electrical sparks are actively melting the metal. Efficient cooling helps to maintain the integrity of both the workpiece and the electrode, preventing excessive wear and potential damage. Additionally, flushing away the molten metal and other debris ensures that the work area remains clear, allowing for effective machining and preventing issues that could arise from accumulated residue. By managing these factors during the Off Time, the EDM process can maintain precision and extend the life of both the tool and the workpiece.
