Deck 39: Form Tolerances

Question 1

Flatness tolerance must be less than the size tolerance and must be contained within the limits of size.

Answer 1

True

Question 2

Common types of errors of circularity include ovality, irregularity, and ____________________.

Answer 2

lobing

Question 3

Noncylindrical parts are features that are circular in cross section but have ____________________ diameters.

Answer 3

variable

Question 4

Form tolerances are used to control straightness, flatness, circularity, and ____.

A) angularity
B) cylindricity
C) symmetry
D) parallelism

Question 5

Since circularity is a form of tolerance, it is directly related to datums.

Question 6

Flatness tolerance means that all points on the surface are contained within a tolerance zone consisting of the space between two parallel lines that are separated by the specified tolerance.

Question 7

A circularity tolerance cannot be modified on an MMC basis.

Question 8

Circularity is similar to straightness except that it is wrapped around a circular cross section.
