Overheard a tool room guy say he checks his backlash before every setup, not just after a crash
I was standing near the tool crib at our shop in Dayton last Tuesday and overheard one of the older guys telling an apprentice that he checks backlash on both X and Y before he runs a single part, every setup, no exceptions. I always figured you check it after a crash or if a finish looks off, but he said he started doing it daily after a 0.003 inch error on a bearing bore cost his old shop about $1,200 in scrap on a 200 piece run. He keeps a dial indicator on his cart and it takes him maybe 90 seconds. I tried it for the past six days on my VF-2 and found my Y was drifting about 0.0015, which explained the taper I kept chasing on bores. Has anyone else made this a habit, or do you just check it when something looks wrong?
