Segment 1
Segment 2
Runout: T
Segment 3
Knife-edge
Laser scan direction
In addition to the diameter, a roller in a paper-
feed mechanism requires a high machining
accuracy with respect to both the roundness and
cylindricity.
In this example suppose that the roller is being
turned to measure the runout.
In the diagram at the right the roller is
turning, and the gap of segment 1 is mea-
sured to determine the runout of T while
segment 2 is measured to determine the OD.
This runout can be derived from the range
(maximum - minimum) of sample measurements.
In this example a knife-edge is used for stable
gap measurement, however, a round pin can
also be used if appropriate.
Here is an example of measuring a rubber roller with a diameter of ø25.0
±0.05
mm and a
runout tolerance of T = 0.03 mm.
