Cylinder Min Value compared to Max Inscribed

I was asked if the measured max inscribed value of a circle/cylinder should be the same as the minimum value measured for that same circle/cylinder.

As far as I understand it, a max inscribed value of a hole is based off of the 3 inner most points to a circular axis. It's the largest virtual or actual pin that will fit in the ID. The minimum value is the point closest to the circular axis, (radius*2). Sometimes max inscribed and min value are the same, sometimes not.

What am I missing.

  • I am measuring a cylinder with 12 hits, 2 levels.


    Cylinders should always (circumstances allowing) be measured with 3 levels to generate a proper vector for the centre axis.
    You should also use an odd number of hits per level (total number depends on size of hole and tolerancing requirements).
