WebMar 3, 2009 · The parallelism requirement and the flatness requirement are separate, but the feature must reside within both zones. The only connection between them is that the flatness tolerance must be smaller than the parallelism tolerance. Evan Janeshewski. Axymetrix Quality Engineering Inc. WebThe flatness tolerance zone is two parallel planes 0.1 mm apart. The size can never be greater than 31 or less than 29. Note below that when the part is created at size 31, the form must be perfect per rule #1. Therefore the tolerance zone has its top plane at 31 and its bottom plane at 30.9.
