Machining of 1.2363 and 1.2343ESR steels using EDM

Popis výsledku v původním jazyce

Electrical discharge machining (EDM) is an unconventional machining technology. It is commonly used in toolrooms to remove the material of the workpiece which in turn gains a negative shape of the electrode – the tool.In order to monitor and model the responses in the form of eroding rate and surface quality, a two-level half-factor experiment was performed with one replication at the corner points and two replications at the central points, for a total of 80 rounds. Both graphite and copper electrodes of sizes 10x10 mm and 100x100 mm were used for eroding and the influence of parameter settings: Open-voltage, Pulse current, Pulse on-time and Pulse off-time was monitored. It was foundthat the shape of the electrode and Pulse current have the most significant effect on the erosion rate.The parameters Pulse current, Pulse on-time and their mutual interaction significantly affect the surface roughness. Statistically significant factors influencing the occurrence of defects turned out to be Pulse current, Pulse on-time and Material of workpiece, where it can be seen that the material 1.2343ESR is significantly less prone to the formation of surface defects.
