WebDec 18, 2014 · Cylindricity is a 3-Dimensional tolerance that controls the overall form of a cylindrical feature to ensure that it is round enough and straight enough along its axis. … WebRoundness = (Dmax - Dmin) / 2 Dmax: Maximum value Dmin: Minimum value DISADVANTAGES There is a limit to the accuracy of the measurement, as the value is an average of two-point measurements. Additionally, an error may occur due to the differences in how the micrometer measurement terminal is placed on the target.
