When to Use Flatness Tolerance?
When Used: When You Want to Constrain the Amount of Waviness or Variation in a Surface Without Tightening the Dimensional Tolerance of Said Surface. Usually...
When applying a flatness tolerance datum referencing is?
The flatness tolerance references two parallel planes (parallel to the surface that it is called out on) that define a zone where the entire reference surface must lie. Flatness tolerance is always less than the dimensional tolerance associated with it.
What is a good flatness tolerance?
A flatness control is applied to the top surface. We know that the flatness applies to the surface because the flatness control points to the top surface. The flatness tolerance zone is two parallel planes 0.1 mm apart. The size can never be greater than 31 or less than 29.
