Concentricity vs true position

WebPosition and concentricity are similar in that they tolerance the axis-to-axis alignment, but how the axis is derived is different. Concentricity asks you to derive the center point … WebConcentricity is normally used for the high-precision parts, and only when there is a critical need to control the mean or median points of that unit. The true functionality of …
