Exam 17: Perpendicularity Tolerance

A common method used to verify a perpendicularity tolerance (MMC) is to use a height gage.

Perpendicularity can be applied to a planar surface, but not to a feature of size.

Where a perpendicularity tolerance is applied to a width, the feature control frame is placed ____________________ (or beside) the size dimension.

What are the four shortcomings of implied 90-degree angles?

Where two datum references are used with a perpendicularity tolerance, the tolerance zone is perpendicular to the primary datum reference.

What are the two common tolerance zones for a perpendicularity tolerance?

Where perpendicularity is applied to a width at RFS, the tolerance value defines the ____________________ between the tolerance zone planes.

A perpendicularity tolerance can only constrain rotational degrees of freedom relative to the datum referenced.

When a perpendicularity tolerance is applied to a planar surface, the deviation is verified by finding the distance between two parallel planes that all of the points of the surface are located within.

Define a precision square and briefly explain how it is used.

____________________ is the condition where a surface, axis, or center plane is exactly 90 degrees to a datum plane or axis.

A general angular tolerance or an angular dimension invokes a(n) ____________________-shaped tolerance zone.

What are the four common real-world applications of a perpendicularity tolerance on a drawing?

In certain applications, part function requires the perpendicularity deviation of a surface to be defined relative to a(n) ____________________.

Where perpendicularity is applied to a planar surface, what are the four conditions that apply?
