WebFeb 12, 2024 · Circularity is a form constraint that measures how well the shape of a part matches a perfectly circular shape. This constraint is sometimes referred to as roundness. It is a two-dimensional tolerance control that is applied to circular cross-sections. The circularity of each cross-section is evaluated independently. WebMeasurements of roundness require 360 traces of the workpiece made with a turntable-type instrument or a stylus-type instrument. A least squares fit of points on the trace to a circle define the parameters of noncircularity of …
