Does anyone know how to (or possibly have already) create a calculator to calculate the tolerance of an angle based on the angularity of the part?
For example: We have a single print for 3 dozen part numbers in the same family of parts. All identical, with the same 93° angle bend, but with the non-datum leg being different lengths. I have inexperienced CMM programmers and press brake operators (and myself included) that can't figure the math to calculate the angle tolerance of the 93° angle because the longer the non-datum leg, the closer to perfect that non-datum leg must be in order for it to meet the same angularity callout.
Does anyone know the formula for creating something like this in Excel, or by chance know if there is a ready made calculator where you can put in the print angle, angularity callout and length dimensions of the legs, and have it tell you how much tolerance you would have on the angle?
