Deck 24: Circular and Total Runout Tolerances

Question 1

In certain applications, the function of a part requires defining the circular runout deviation of a planar surface perpendicular to a datum axis. Where circular runout is applied to a planar surface, The tolerance zone limits deviations in form, orientation, and location of the circular element.

Answer 1

False

Question 2

When establishing a datum axis, a single diameter is used where the ____________________ orients the parts in assembly.

Answer 2

diameter

Question 3

The maximum possible axis offset in a runout application (circular or total) is equal to ____________________ the runout tolerance value.

Answer 3

one-half
1/2
one half

Question 4

In certain applications, the function of a part requires defining the circular runout deviation of a diameter relative to a datum axis. In this application, the ____________________ must meet its size requirements.

Question 5

In certain applications, the function of a part requires defining the total runout deviation of a diameter relative to a datum axis. In this application, the tolerance value defines the radial distance between the tolerance zone cylinders.

Question 6

Define runout.

Question 7

When establishing a datum axis, where the surface is the primary datum feature, the diameter should be long.

Question 8

A(n) ____________________ runout tolerance is a geometric tolerance that limits the high to low point deviation of all surface elements of a cylindrical surface, or all surface elements of a planar surface that is perpendicular to and intersects the datum axis. It is measured normal to the surface elements.

Question 9

Where circular runout is applied to a cylindrical surface, the tolerance zone is two coaxial circles centered on the datum axis.

Question 10

What are three common real-world applications of circular and total runout tolerance?

Question 11

What are the four common runout tolerance zone shapes and on what two factors do they depend?

Question 12

Where circular runout is applied to circular elements constructed around a datum axis, it limits the deviations in circularity, orientation, and axis offset (location).

Question 13

What are the three methods used to establish a datum axis for a runout tolerance specification?

Question 14

What are the two parts of verifying a runout tolerance applied to a cylindrical surface?

Question 15

Where circular runout is applied to a planar surface at a(n) ____________________ angle to a datum axis, it controls deviations of the circular elements of the plane for wobble, which includes orientation and form deviations of the circular elements.
