312 Geometric Dimensioning and Tolerancing Copyright Goodheart-Willcox Co., Inc. 5. Describe a practical application in which a perpendicularity tolerance is used to control perpendicularity of a feature axis relative to the axis of another feature. Explain how the feature control frame is composed and placed on the drawing and describe how the tolerance zone is established. _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________ 6. Describe a practical application in which an angularity tolerance is used to control angularity of a surface.

Describe a practical application in which zero geometric tolerance at MMC is specified for a perpendicularity tolerance controlling a feature of size. Show calculations for the geometric tolerance through a range of produced sizes between MMC and LMC. _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________ _ _____________________________________________________________________________
