We are setting up a Gage Control program for a sheet metal fabrication shop. Gages used include tape measures, steel rules, combination squares, dial calipers, some go/no-go gages.
We have a certified 24" steel rule for verifying tapes, steel rules and a set of certified standards for verifying calipers, micrometers.
How do we verify combination squares and protractors?
Print tolerances are +/- .030 for most dimensions and +/- 1 deg for formed angles. BH
