Using Three (3) Gage Pins to Check Hole Ø
I'm looking for the formulas to calculate what three (3) different sized gage pins that would combine to form the desired final diameter such that three smaller diameters would be tangent to each other and the circumscribed OD (plus the calculation of the reverse).
ØA & ØB &ØC = ØD
The goal is to setup a spreadsheet where an inspector could enter the size hole that they would like to check and the formula would spit out the three (3) pin sizes that would combine to get that number.
Alternatively, the inspector could enter three (3) pin diameters that combine to fit the part and the formula would return the resulting OD.
NOTE: the use of the term OD is this case refers to the larger diameter that would tangent to the three (3) gage pin diameters used to check the part.
