Deck 26: Profile Tolerance - Basic Concepts

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.

Answer 1

line

Question 2

Define a non-uniform tolerance zone.

Answer 2

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.

Answer 3

False

Question 4

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

Question 6

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

Question 7

Profile tolerances need to be specified with datum references.

Question 8

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

Question 9

Multiple profile tolerances can be applied to a single surface.

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.

Question 11

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

Question 12

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

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.

Question 14

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

Question 15

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