We do not have the opportunity to quote work for German companies, hence we are not "up" on print tolerance annotation.
In the US, we use +/- to indicate allowable deviation from the intended nominal dimension.
We received prints from a German company indicating + 0.045
18 + 0.025
This would indicate to us that the minimum is 18.025 and the max is 18.045 with a nominal dimension of 18.035. Would this be an accurate translation?
What is the intent of +/+ dimensions as opposed to +/-?
There has been much internal discussion (without benifit of German expertise) on what this dimension style really means to our shop.
