I was tasked to run an old type E wire eroder which I managed to do ok-ish.
This sparked an idea and I set about trying to cut thin 0.004" stainless sheet as quick as possible. After tweaking the power settings I managed to cut in full rapid around 12 in/min.
Unfortunately the max profiling feedrate of the machine control is around 0.150"/min
Is there any way I could manipulate the dry run switch to still have the generator active (cut mode) and be able to cut at full rapid speed ?
For those interested, we make a thin sheet component that is currently stamped out, we then one by one, manually load the parts into a precision locating fixture and spot weld two small pins to the part.
As these profile shapes are constantly being changed it costs a lot to keep making press tools and also the manual welding operation is very tedious.
I`d like to build a small cnc machine that would cut the profile from the sheet and a gripper would be used to automatically move the profile into a welding stage.
I have thought of using a plasma cutter but am not sure if the lowest setting, around 10 amps would be to much for the thin sheet.
