Ok, here is a question for the "old timers"
I have a fixture I've been using on a production part for quite a while now. It is made of 6061 AL.
This morning I've set the job up, and during a momentary lapse of sanity loaded the wrong program, thereby cutting the fixture in half.
Ok, no problem, let's make a new one but this time out of say.....303SST.
Done. Loaded the fixture, set everything up the way it's always been....
Wire gets to the part, no spark, short circuit.
Did it again... same thing.
Ok, not enough ground, quickly hooked up a piece of copper wire, attached to the part.. same thing.
No matter what I've tried to do, could not cut the damm thing.
Back to the drawing board, made a new fixture, this time out of brass.
Loaded, started, all is well. Except the cycle time is 15% longer. 7min 20 sec. instead of a 6 min 10 sec.
Can some of you fine fellas shed some light on this please?
