WebCirc.(circularity): 4π*area/perimeter^2. A value of 1.0 indicates a perfect circle. As the value approaches 0.0, it indicates an increasingly elongated shape. Values may not be valid for very small particles. AR(aspect ratio): … WebCircularity or roundness is a form control that may be applied to any feature containing circular slices. The tolerance zone for circularity is the annulus area between two circles with the same center. The width of the zone is the difference between the radii of the two concentric circles.

WebJun 3, 2024 · Roundness measuring instruments are used to measure cylindricity and circularity. To verify the accuracy of a cylindrical feature, we check for radial as well as longitudinal distortion in the cylinder. In order … WebTwo-point measurement is performed on the outer form by dividing it into four to eight sections.

WebApr 14, 2012 · It depends on the stack. But if the stack goes across the part or includes the diameter tolerance in any way, then the roundness tolerance is ignored. This is because the roundness must operate within the size limits, and never go beyond them.
