Name seven conditions that apply when a profile of a surface tolerance is applied to a planar surface.
What will be an ideal response?
ANS:
In certain cases, the function of a part may require that a surface be located relative to a datum reference frame. This may be accomplished with a profile of a surface tolerance. In this application, profile is applied to a planar surface, and the following conditions apply:
1. The profile tolerance is applied to a true profile.
2. The true profile is related to the datum reference frame with basic dimensions.
3. The datum reference frame is three orthogonal planes.
4. The tolerance zone is a boundary 1.0mm wide centered on the true profile.
5. There are no additional tolerances available.
6. All surface elements must be located within the tolerance zone.
7. The tolerance zone limits deviations in location, orientation, and form.
