I have a customer that has to meet military contracts and tolerances. There is a OLD print we are going through that has an odd flatness callout. I have read thousands of prints and never seen it given this way. It makes sense to me that it is .005" per every .5" inches. In other words it would have to be flat within .01" and it cannot vary more than .005" per every .5"...
The other question with this is if we have a flat surface and can fit a .005" feeler cage under the part for a 2" distance the part would be good still right? The .01" feeler gage does not go under the part so it is within .01" flatness. I know the best way to check is with an indicator (and part sitting flat) or CMM but I do not have a way to make either of these happen and the customer wants to use this flat plate and a feeler gage.
