307 Copyright Goodheart-Willcox Co., Inc. Chapter Review Name _____________________________________________________________________ Know and Understand Answer the following questions using the information provided in this chapter. True/False _____ 1. True or False? Orientation tolerances control the angular relationships of features to one another. _____ 2. True or False? Orientation tolerances are not related to datums. _____ 3. True or False? Where it is desirable for an orientation tolerance to control only individual line elements, rather than an entire surface, the note EACH ELEMENT is placed inside the feature control frame. _____ 4. True or False? Orientation tolerances control flatness. _____ 5. True or False? Orientation tolerances applied to features of size imply MMC. _____ 6. True or False? Parallelism is the condition of a surface, center plane, or axis at a right angle (90°) to a datum plane or datum axis. _____ 7. True or False? A parallelism tolerance specifies a tolerance zone formed by two parallel planes or parallel lines, or a cylindrical tolerance zone, oriented parallel (basic 0°) to a datum and within which the controlled surface, axis, or center plane of the feature must lie. _____ 8. True or False? A tangent plane is a plane that contacts the high points of the specified surface. _____ 9. True or False? A parallelism tolerance used to specify a control for a feature axis establishes a tolerance zone defined by two parallel lines oriented parallel to a datum plane and within which the feature axis must lie. _____ 10. True or False? A perpendicularity tolerance specifies a tolerance zone formed by two parallel planes or parallel lines, or a cylindrical tolerance zone, oriented parallel (basic 0°) to a datum and within which the controlled surface, axis, or center plane of the feature must lie. _____ 11. True or False? Parallelism and perpendicularity controls can be combined using a multiple single-segment feature control frame. _____ 12. True or False? An angularity tolerance specifies a tolerance zone formed by two parallel planes or parallel lines, or a cylindrical tolerance zone, oriented at any specified basic angle to a datum and within which the controlled surface, center plane, or axis of the feature must lie. _____ 13. True or False? When applying an angularity tolerance to a surface, the feature control frame normally connects to the surface by a leader, but it can attach to an extension line from the surface. _____ 14. True or False? Placing the MMC material condition symbol after an orientation tolerance in the feature control frame means that the geometric tolerance is the same when the feature is manufactured at any produced size.
