Exam 13: Geometric Dimensioning and Tolerancing

Define datum feature.

How are basic dimensions shown on a drawing?

Define form tolerances.

Name the five types of geometric characteristic symbols.

Given the following drawing, describe the profile geometric tolerance and related drawing specifications. Indicate whether the drawing shows preferred ASME Y14.5 use or an alternate practice.

Define actual mating envelope.

Completely define the term basic dimension.

Give the proper abbreviation and definition for regardless of material boundary.

What information is placed in the lower half of the datum target symbol?

Given the following drawing and a list of possible produced sizes, specify the geometric tolerance at each possible pro- duced size.

Name the following symbols and identify the proper draft- ing dimensions and features C through G and put symbol name at A and B.

When using composite positional tolerancing, the upper part of the feature control frame is referred to as the and specifies the larger tolerance for the pat- tern of features as a group, while the lower half of the frame is called the and specifies a smaller positional tolerance for individual features within the pattern.

Give the formulas for calculating virtual condition for inter- nal and external features. Internal feature: External feature:

What is the difference between the appearance of the feature control frame used for a composite positional tolerance and the one used for a positional tolerance with two single segments?

How are datum target areas treated on a drawing when the target area is too small to draw?

Describe the purpose of location tolerances.

Define radial element and describe how a radial element specification is applied to a drawing.

How is a feature control frame connected to a related fea- ture when surface control is intended?

Two or more surfaces that are on the same plane are re- ferred to as surfaces.

Give the formulas for internal and external features that can be used when calculating the positional tolerance at any produced size when LMC is applied to the positional tolerance.
