Just changed my approach after a QC guy called me out on edge breaks

Last month a quality inspector told me all my parts had inconsistent edge breaks, like some were .005 and others were .015. Turns out I was relying on feel instead of actually measuring with a comparator gauge. Anybody else get chewed out for something you thought was fine until someone pointed it out?

Get yourself a set of gauge blocks and a comparator. Makes a huge difference. I had the same thing happen with a QC manager who ran my parts across a comparator and showed me how bad my hand feel actually was. Now I check every tenth edge break with a gauge block before I call it good. Your fingers just can't feel .005 vs .010 no matter how much experience you have.

Had a similar wake up call a few years back. I always thought my edge breaks were close enough because I could feel them by hand. Then a customer sent back a batch because the breaks were all over the place, from .002 up to .020. That was a tough lesson. Now I use a comparator gauge for every single part, no exceptions. It adds a few seconds per part but saves a ton of rework. Once you see the actual numbers, you realize your fingers are terrible at measuring tenths.

Comparator gauges are a real eye opener... I used to think my edge breaks were perfect until a guy showed me the numbers on a optical comparator. Now I double check everything with a gauge block just to be safe. It's amazing how much our hands lie to us about those tiny measurements.
