The reading and interpretation of the example in figure 1 above is as follow. The axis of the pointed vertical hole should lie within its tolerance zone. WebThe cone angle value is calculated by taking the upper and lower roundness planes of a cylindricity analysis. A least squares circle is fitted to each plane and the cone angle is calculated from the radial difference of the two circles over the Z height separation, as shown in the formula above.
