Exam 13: Geometric Dimensioning and Tolerancing

A tangent plane modifier would not include which of the feature control symbols?

The need to tolerance more than just the size of an object led to the development of geometric dimensioning and tolerancing.

This feature control specifies that all points on a surface must be an equal distance from a datum.

This feature control is normally used for controlling arcs and curves.

The concept that some parts vary in form beyond the MMC size limits after manufacture is:

Rule #1 states: "Where only a tolerance of size is specified, the limits of size of an individual feature define the extent to which variations in its geometric form, as well as size, are allowed."

This type of tolerance is used for parts made up of several subparts all sharing the same center line or axis.

To indicate that a specified tolerance applies to the entire part, use the _____ symbol.

The term regardless of feature size is a modifier that tells machinists that a tolerance of form or position or any characteristic must be maintained, regardless of the actual produced size of the object.

A runout tolerance requires a datum reference.

Datums are components of a part such as a hole, slot, surface, or boss.

The three types of size tolerances are unilateral, location, and runout.

The MMC of an internal feature is the smallest allowable size.

Which of the following is not true regarding feature control symbols?

This type of tolerance is used to locate features of parts that are to be assembled and mated.
