Cylinder measuring
 

I'm having trouble with measuring a cylinder cut by 2 non-perpendicular planes. Can anyone tell me the mathematical fundamentals of the measurement? How can they determine thw radius with only 6 points? Thank you!johnnyaxle

I don't know the math for solving a cylinder with 6 points, but what is the problem you are trying to solve? Is it that you cannot get enough hits on it? That the hits are not normal to the surface? That the cylinder does not repeat? That you don't know the nominal data? DOes it not learn well?

Please elaborate on the fundamental problem, and perhaps we can find a solution. . .Don Ruggieri
