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.:withstupi
