Deck 45: Runout Tolerances

Question 1

Circular runout provides control of circular elements and features at right angles to circular elements.

Answer 1

False

Question 2

The two types of runout control are circular runout and ____________________ runout.

Answer 2

total

Question 3

When testing circular runout, the tolerance is applied independently at any cross section as the part is rotated ____.

A) at high speed
B) 360°
C) at low speed
D) 180°

Answer 3

B

Question 4

The only way to check circular or total runout is to hold the part between centers positioned precisely on each end of the datum axis on each end of the part.

Question 5

Errors in circular runout can be caused by eccentricity and errors or ____.

A) cylindricity
B) concentricity
C) straightness
D) roundness

Question 6

When checking total runout, the checking indicator must traverse the full length or extent of the surface while the part is revolving about its datum axis.

Question 7

When applied to surfaces constructed around a datum axis, circular runout controls variations such as circularity and ____________________.

Question 8

Total runout involves the runout of each circular element along the part or feature.

Question 9

In applying runout tolerances, both the tolerance and the datum feature apply only on an RFS basis.

Question 10

When a runout tolerance applies to a specific portion of a surface, a thick ____________________ line is drawn adjacent to the surface profile to show the desired length.

Question 11

The symbol for circular runout is ____.

A)
B)
C)
D)

Question 12

The symbol for total runout is ____.

A)
B)
C)
D)

Question 13

The types of features controlled by runout tolerances include those surfaces constructed around and at right angles to the ____________________ axis.
