Figure 7: Swing overtravel and additional withdraw

In cases when a fin is observed at the root bottom, the feature fin removal can
be activated. This feature will only work after each second cut flank. This
means if all lower flanks are cut first, then the fin removal works after the cut-
ting of each upper flank. Fin removal amount is the amount the cutter moves
from the fillet of the second cut flank towards the first cut flank. For example, if
the smallest slot width (e.g. at midface) is 7mm and the blade top width is 3mm
then the cutter can maximally move 4mm sideways towards the first cut flank
until it contacts the first cut root fillet. A typical input is 0.6mm fin removal
amount and 6 fin removal passes (6▪0.6=3.6mm which leaves 0.4mm clear-
ance to the first cut root fillet.
