Question 1

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

Accepted Answer

Verifying a runout tolerance applied to cylindrical surface has two parts:
1. Establishing the datum axis RMB
2. Verifying the radial deviation of the surface elements are not greater than the specified runout tolerance

Question 2

Define runout.

Accepted Answer

Runout is the deviation of the surface elements relative to a datum axis. The deviations may be on a surface of revolution co- axial to a datum axis or on a planar surface that is perpendicular to and intersects a datum axis. There are two types of runout tolerances: circular runout and total runout.

Question 3

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

Accepted Answer

There are four common runout tolerance zone shapes. The shape of the tolerance zone depends upon two factors:
1. The type of runout (circular or total)
2. The type of feature to which the runout is applied (cylindrical or planar surface)
The four common tolerance zones are:
Circular Runout
1. The radial space between two coaxial circles
2. The axial space between two coaxial circles (offset axially)
Total Runout
1. The radial space between two coaxial cylinders
2. The axial space between two planes (offset axially)

Question 4

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

Accepted Answer

A) True 
 B)False

Question 5

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.
