measured with a dish tip dial indicator (Figure 33, right side). The indicator is
zeroed at blade number 1 and all other blades are adjusted to within a toler-
ance of +/- 0.008mm. The axial cutting edge runout can be measured, howev-
er it doesn’t have to be trued if the runout is between +/-0.010mm.

At the end of the build procedure, the effective cutter diameter is measured
with a vernier caliper as shown to the left in Figure 34 on two opposite blades.
The cutter reference height is measured with a height measurement gage
which had been referenced to zero on the CCB spindle face (right photo in
Figure 34). It appears that the height gage will not be able to capture the posi-
tion of the blade reference point precisely because it contacts the edge radius.
However, each Coniflex cutting and grinding summary has a pre-calculated
reference height correction item. The machine control uses this small number
in order to improve the accuracy of the measured cutter or wheel reference
height.

In case of a Uniflex cutter or grinding wheel, it will not be possible to find the
highest point of the cutting edge at the blade tip region as indicated in the right
photo of Figure 34.
