Circularity roundness
WebSometimes called roundness, circularity is a 2-Dimensional tolerance that controls the overall form of a circle ensuring it is not too oblong, square, or out of round. Roundness is independent of any datum feature and only is always less than the diameter dimensional tolerance of the part. WebThe circularity control (e) defines how much the cross-sections of a surface of revolution on a real part may vary from an ideal circle. Tolerance Zone: The circularity tolerance zone is the area between two concentric circles that are perpendicular to the features axis or in the case of a sphere the circles share the same center point as the ...
