Question 1

A profile of a(n) ____________________ tolerance is a geometric tolerance that establishes a two-dimensional tolerance zone that is normal to the true profile at each line element.

Accepted Answer

line

Question 2

Define a non-uniform tolerance zone.

Accepted Answer

A non-uniform tolerance zone is a maximum material boundary and least material boundary of unique shape that encompasses the true profile.

Question 3

Profile tolerances cannot control orientation and location.

Accepted Answer

Profile tolerances can control form, orientation, location, and sometimes size, depending on how they are specified in the drawing. They are versatile in geometric dimensioning and tolerancing (GD&T) for defining complex shapes and surfaces.

Question 4

What are the five types of tolerance zones that may be used with a profile tolerance?

Accepted Answer

The answer of What are the five types of tolerance...

Question 5

A(n) ____________________ profile is a profile located and defined by basic radii, basic angular dimensions, basic coordinate dimensions, basic size dimensions, undimensioned drawings, formulas, or mathematical data, including design models.

Accepted Answer

A profile defined by basic radii, angles, coordinates, dimensions or mathematical data is known as a parametric profile.

Question 6

What are the four methods to extend the coverage of a profile tolerance zone?

Accepted Answer

The answer of What are the four methods to extend...

Question 7

Profile tolerances need to be specified with datum references.

Accepted Answer

Profile tolerances can be specified without datum references when controlling the form of a feature. Datum references are used when the orientation or location of the profile needs to be controlled relative to other features.

Question 8

What are three important advantages of profile tolerances in comparison to coordinate tolerances?

Accepted Answer

The answer of What are three important advantages of profile...

Question 9

Multiple profile tolerances can be applied to a single surface.

Accepted Answer

It is possible to apply multiple profile tolerances to a single surface, as long as they do not conflict with each other.

Question 10

A profile is an outline of a surface, a shape made up of one or more features, or a two-dimensional element of one or more features.

Accepted Answer

This is the definition of a profile.

Question 11

A(n) ____________________ tolerance zone is a tolerance zone that is offset to one side of the material.

Accepted Answer

The answer of A(n) ____________________ tolerance zone is a tolerance...

Question 12

All applications of profile tolerances control form, and (depending upon the application) a profile tolerance may control ____________________ (or alignment) or size.

Accepted Answer

The answer of All applications of profile tolerances control form,...

Question 13

A profile of a (n) ____________________ tolerance is a geometric tolerance that establishes a three-dimensional tolerance zone that extends along the length and width (or circumference) of the considered feature or features.

Accepted Answer

The answer of A profile of a (n) ____________________ tolerance...

Question 14

A profile tolerance should never be attached to a basic dimension.

Accepted Answer

A profile tolerance is used to specify the allowable variation in form, orientation, location, and runout of a feature. It should be applied to a feature control frame, not a basic dimension. Basic dimensions define the nominal geometry of a part, and attaching a tolerance to them would imply that the nominal dimension has a tolerance zone, which is incorrect.

Question 15

What are the four types of part deviations a profile tolerance can affect?

Accepted Answer

The answer of What are the four types of part...
