Similar to other geometric tolerance group, run-out can be split into two categories, a 2D (circular run-out) and 3D (total run-out) variant. Circular run-out can control the circularity of a feature relative to the components axis bounded by a 2D tolerance zone. This can be considered as measuring a combination of the component’s co-axiality and…
Total run-out can control the cylindricality of a feature relative to the components axis bounded by a 3D tolerance zone combing the applied control of co-axiality and cylindricality. Unlike circular run-out, total run-out is a measure of the full length of the applied surface as the part is rotated. Controlling other Features with Run-Out Both…
