WebCircularity is often described as the round version of straightness, in that it only measures a single cross section at a time. Circularity specifies a circular TZ, or a TZ framed by two... WebThese are the GD&T parameters that control radial deviations on parts having a round cross section. To help you better understand the differences and how they relate to one another, we have broken down the terminology for you. Roundness, or circularity, is the 2D tolerance that controls how closely a crosssection of a cylinder, -
