Parameters on the Cycle form
JK
Cutter position
 JK=0: On the contour
 JK=1, closed contour: Within the contour
 JK=1, open contour: Left of the contour
 JK=2, closed contour: Outside the contour
 JK=2, open contour: Right of the contour
 JK=3: Depending on H and MD
H Cutting direction
 0: Up-cut milling
 1: Climb milling
P Maximum infeed
I Contour-parallel oversize
K Infeed-direction oversize
FZ Infeed rate
E Reduced feed rate
R Approach radius
O Plunging behavior
 0: Straight (vertical plunge)—The cycle moves the tool to
the starting point; the tool plunges at feed rate and mills
the contour.
 1: In predrilling—The cycle positions the tool above the
hole; the tool plunges and mills the contour.
NF Position mark (only if O=1)
RB Return plane
