328 Copyright Goodheart-Willcox Co., Inc. GD&T: Application and Interpretation 6. Datum feature references in a position tolerance specification result in dimensional requirements being related to _____. A. datum feature surfaces B. assumed locations C. reference points D. a datum reference frame 7. The tolerance zone is unchanged by the produced feature size when _____ is applicable to the tolerance. A. LMC B. RFS C. MMC D. All of the above. 8. A tolerance specification on a hole has an MMC modifier. For every .002″ departure of the hole’s unrelated actual mating envelope diameter from MMC size, the tolerance zone increases _____. A. .001″ B. .002″ C. .004″ D. None of the above. 9. A dowel pin pressed into one part and passing through a clearance hole in another part is an example of a(n) _____ fastener application. A. fixed B. floating C. standard D. unusual 10. If a hole is .001″ out of the acceptable tolerance zone and the tolerance is specified at MMC, it might be possible to make the hole acceptable by _____. A. reducing the hole diameter B. moving the hole C. increasing the hole diameter D. None of the above. 11. The use of a round tolerance zone for a position tolerance increases the tolerance zone area by _____ in comparison to the area of a square zone. A. 25% B. 57% C. 125% D. None of the above. 12. When one position tolerance feature control frame is applicable to a hole and counterbore, the axis of the counterbore _____ the axis of the hole in their respective position tolerance zones. A. is free to move in a direction opposite of B. must move in the same direction as C. must remain coaxial with D. None of the above. 13. A position tolerance applied to a thread controls the location of the _____ diameter unless indicated otherwise. A. minor B. pitch C. major D. root 14. A position tolerance applied RFS to a slot controls _____ of the slot. A. the center plane B. the axis C. one side D. both sides 15. An advantage of using position tolerances is _____. A. clarity B. flexibility in usage C. MMC additional tolerance D. All of the above. True/False 16. True or False? Position tolerances are used to specify the required location accuracy for features of size. 17. True or False? Implied datums are used in design documentation to allow the machinist to select the features to use as datums. 18. True or False? A floating fastener condition exists when a bolt passes through a clearance hole in one part and threads into a hole in the second part. 19. True or False? A round tolerance zone has a smaller area than a square tolerance zone for the same application. 20. True or False? Additional tolerances resulting from departure from MMC cannot be achieved when using directly applied plus and minus tolerances on location dimensions.
