Had a tool offset error cost me a $1,200 job in Houston last month
Was running a production run of aluminum brackets on my Haas VF-2. Everything looked good on the first part, but I didn't double check my tool 4 offset after a tool change. Ended up cutting 47 parts 0.015" undersized before I caught it. Scrapped the whole batch and the customer was pissed. Now I always run a test ring after every tool change, even if it adds 30 seconds to cycle time. Anyone else have a stupid mistake like this wreck a big order?

I nuked $800 worth of delrin once from the same exact mistake.

Double down on that 123 block idea and keep a dedicated test part nearby too... I've got a scrap bracket I always run through after a tool swap just to eyeball the dimensions. It's saved me more times than I can count, especially when I'm in a hurry and feeling lazy. That extra minute beats scrapping a whole batch any day.

Heard a guy at the local shop talk about this. Said he keeps a cheap 123 block on the table just for quick dry runs after swaps. Saves him from the same headache.
