smart.Turn units for the Y axis
3.3 Units—Milling in Y axis
"ICP contour milling in YZ plane" unit
The unit mills the contour defined with ICP in the YZ plane.
Unit name: G840_Kon_Y_Mant / Cycle: G840 (see page 351)
Access to the technology database:
 Machining operation: Finish-milling
 Affected parameters: F, S, FZ, P
Parameters on the Contour form
FK
see page 60
NS Starting block no. of contour
NE End block no. of contour
X1 Milling top edge (diameter value)
P2 Depth of contour (radius value)
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 (diameter value)
