Get a call the other day from a good customer, he wants to reorder some parts we've done before and he'd like them soon. Sweet! Stock is on the shelf, soft jaws are done, programs are all validated and I got plenty of tools so let's rock. Setup parts (4, 2 in each vise) need no tweaks so this is going great, and I run (4) more.
Next run, part #1 pulls out and trashes a fresh 1/2" 5fl, well shit. Start over with new stock in hole #1 and then part #2 pulls out and wrecks another 1/2". Huh? Repeat with fixtures #3, 2x and I'm down 4 end mills with 7 parts on the table. This is absurd! WTF?!?
The damn bar ends (1144 stressproof) were somewhere between .010 and .017" undersized. I'd my cut setup parts with remnants from the last batch, as well as parts 1-4, come parts 5-8 I'm just grabbing from the pile at the bandsaw and just by chance putting an undersized part in. No matter how tight the vise was, one was loose so it'd pull into the cutter during facing and then that all to familiar whirrrrr...WHIIIRRRRR....TINK!
So there I am, limping through the run with a tool missing flutes 3 & 4 at 50% speed. Partly because I'm tired of breaking $60 tools, and partly because I'm now leery as hell of the setup.
I also broke a Haimer tip and dropped my ear phones in the coolant sump, I need a beer.
