The engineers asked me to bisect a part so they could inspect a couple welds. I NAILED it. A few hours later, they came back and asked if I could remove another slice at an angle because they thought the EDM wire might have been getting stuck in the cracks (this is not how EDM works, the wire NEVER touches the part, because if it does that means you get no sparks, and no cut... but regardless).
So here I am, the first cut was already diagonal so I could get both welds in one slice, now I'm fixturing this shit up on a sine plate, indicating the part to get it lined up again, trying to rotate a diagonal plane in 3D space and only give it a couple thousandths of an inch shave.
I managed to pull it off, but it took a couple shaves. I had to cut off about .008 inches to get a clean cut.
It's a part with a cylindrical shaft bolted to a V-block bolted to a sine plate bolted to the table of a wire EDM machine. The part is being probed with a dial test indicator in a futile attempt to line it up with the machine's vertical axis. In other words, it is a shitshow.
Sweet. I didn't think any trades people were on here. Bookmarking this for my future EDM questions
Fucking engineers. They really gotta learn to do some of that shit themselves.
@PorkrollPosadist you ever seen an aerospace engineering student make a drill press scream for 20 minutes because they don't know they need to change the speed?
