What is the circularity tolerance zone?
What will be an ideal response?
ANS:
The tolerance zone for a circularity tolerance is the space between two coaxial circles on any cross section plane perpendicular to the axis or spine. The tolerance zone circles may be best fit to the part circular element, or they may be established by a method that fits one of the tolerance zone circles to the part circular element. The outer circle may be the minimum circumscribed circle, or the inner circle may be the maximum inscribed circle. When the outer or inner circle is established, the second circle is coaxial with the first circle. The circularity tolerance value defines the radial distance between the circles.
