| Can anyone help us? I'd appreciate it if some one could give us some EDM data.We're going to make some cavities in aluminum, .75x.375, Depth 2.5 inches. We are completely new to this. Machine is a Hurco EDM. We need: On Time Off Time Amp. Work time Up Time Voltage to get it done as fast and as accurate as possible. Do you have to do a rough run before finishing the hole? Thanks in advance.
