cutter spindle deflection but also the compliance in the gear train of the CB
Machine as well as the compliance of the rotational positioning device will
cause the blade tip to slide a small amount vertically down. After releasing
the torque wrench, the blade tip slides back into the initial position. Also, the
blade tip sliding can cause small chipping on the blade tip.

The lower photo in Figure 5 demonstrates the ideal condition while torquing
the clamp screws. The wrench handle points in the 6’o clock position. While
the force on the handle is applied, deflections and compliances will move
the blade away from the carbide stop. This condition poses the lowest likeli-
hood of blade tip damage.

Following the correct procedure will make the difference between excellent
and poor tool life. The cutter building and blade truing time on the cutter
build machine will have its payback in lesser frequent cutter change and cut-
ter building.

28.4 Probe Setup

For trueable cutter heads, the probe setup screen (Figure 6) will show the
probe zeroing button, which is not required for the new truing procedure.
