Re: Confused about Calibration Tolerances of Plug Gauge, Ring Gauge & Snap Gauge
What are the Gage makers tolerance for the plug and ring gages, once you have these tolerances you can wright a procedure and create you own wear limits. for the tolerances you are working too. For example you have a plug gage with a Gage makers tolerance of +.00002 on a plug gage size of .250000, your tolerance on the parts you are checking is +/-.0010, you could specify that the wear limit is -.00004, when you plug reaches .249980 you discrd the plug member and purchase a new member. hope this helps.
