The curve is the rotary cut function entry curve. When the rotary cut function is started up, the rotary cut
axis will follow the feed axis to rotate according to the curve. The entry position is based on the rotary
cut axis. For the single knife, the cutting position is directly below the rotary cut roller if the entry position
is over the rotary cut roller in the following figure. Before the rotary cut function is started up, the knife
must be turned to the upper of the rotary roller. Otherwise, the cutting may happen in the adjustment
area.
