Exam 13: Geometric Dimensioning and Tolerancing

Define tangent plane.

Give the formula used to determine the positional tolerance of a fixed fastener.

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

Given the following drawing, a reference chart showing a range of possible produced sizes, and four optional feature control frames that can be applied to the diameter dimen- sion, provide the positional tolerance at each possible pro- duced size for each feature control frame application.

The tertiary datum plane must be established by at least point(s) on the tertiary datum surface.

Define true position.

Any letter of the alphabet can be used to identify a datum ex- cept for , , and .

Under which condition(s) is a projected tolerance zone recommended?

Name each of the following geometric characteristic symbols.

Identify the two ways that a projected tolerance zone can be shown on a drawing.

Which geometric tolerance is characterized by any given cross section taken perpendicular to the axis of a cylinder or cone or through the common center of a sphere?

Give the formula used to determine the positional tolerance of a floating fastener.

Define parallelism.

A(n) geometric tolerance zone is established by two parallel planes at any specified basic angle, other than 908, to a datum plane or axis. The specified angle must be , and it must be dimensioned from the plane.

Define tangent plane and describe the relationship among the actual surface, the tangent plane, and the geometric tolerance.

Give the formulas for calculating the slot boundary when applying positional tolerancing to slotted features.

Identify at least five locations where a feature control frame can be placed on a drawing.

List the five basic types of dimensioning and geometric tolerancing symbols.

Describe how to properly display the symbols for a circular datum target area, a square datum target area, a rectangular datum target area, and a spherical datum target area.

Name the following symbol and identify the proper drafting dimensions B through F and put symbol name at A.
