5.3.6.2 Odd-numbered-edge cutting tool run-out measurement
Measure the run-out of the cutting edge of the odd-numbered-edge cutting tool as follows.
As shown in the figure below, set the measuring rage so as to separately contain each cutting
edge.
Measure the minimum value of Segment 3 in each edge measuring range through the
“Sample measurement”.
Calculate the range (maximum - minimum) of the measured data as many as the number of
cutting edges being set, and display the result as the measured data of “Run-out”.
This method can be applied to any run-out measurement of even-numbered-edge cutting tool
and gear teeth (teeth tips), etc. beside an odd-numbered-edge cutting tool.

(*1): At the stage when “ ” is set from the “Calculation item”, the available
segments will be automatically set and the guidance for that item will not be dis-
played any more.
(*2): It is necessary to measure the workpiece (odd-numbered-edge cutting tool) while
rotating it. Determine the number of averaging times depending on the number of
workpiece revolutions.
(In this example it is assumed that the number of workpiece revolutions is approxi-
mately 4 rpm.)
