Well, I've been fighting with a few parts at work since last Wednesday, and I thought I'd share a bit of what we actually
do where I work.
The parts are an assembly for a Forming Die, using heat and vacuum to create a pocket in which a "cannula" will be sealed. That's a sort of an I.V. needle...
The problem has been, the die is a big plate, 1.25" x 6.1" x 15.5" with pockets in it.
But the bitch, is that the formed pockets need these little "tear drop" shaped features in them, and they're undercut, so the engineer had to design separate pieces and insert them into the die.
These parts must match PERFECTLY, or the lines will show up in the plastic packaging.
I had to design a "jig" to hold the little bastards so we could machine all around it in one shot.
The inserts are less than an inch square...
I finally got everything dialed in tonight,
Here's a few pics of one of my many test plates...
