What does it mean when a feature control frame with a parallelism geometric characteristic symbol is placed with a diameter dimension? _ _____________________________________________________________________________ _ _____________________________________________________________________________ 6. Define tangent plane and describe the relationship between the actual surface, the tangent plane, and the geometric tolerance zone. _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________ 7. How must a feature control frame be modified where it is desirable to control only individual line elements rather than the entire surface? _ _____________________________________________________________________________ _ _____________________________________________________________________________ 8. Identify the condition that exists when all points on a surface or center plane are equidistant from a datum plane. _ _____________________________________________________________________________ 9. Identify the condition that exists when a surface, center plane, or axis is at a right angle (90°) to a datum plane or datum axis. _ _____________________________________________________________________________ 10. A _______________ tolerance specifies a tolerance zone formed by two parallel planes or parallel lines, or a cylindrical tolerance zone, oriented perpendicular (basic 90°) to a datum. 11. When a slot is specified as perpendicular to a datum plane, the feature _______________ is held within two parallel planes perpendicular to a datum plane. 12. Explain the required tolerance zone established by an angularity tolerance. _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________ 13. When applying an angularity tolerance, the specified angle must be _______________ and dimensioned from the datum feature. 14. When specifying zero geometric tolerance at MMC for an orientation tolerance, what is required when the feature is at the MMC size? _ _____________________________________________________________________________ _ _____________________________________________________________________________
