336 Cycle programming
4.8 Milling cy
cles
T Turret pocket number
ID Tool ID number
S Spindle speed/cutting speed
F Feed per revolution
Cycle parameters (second input window)
I
Contour-parallel oversize
K Infeed-direction oversize
P Infeed depth (default: total depth of one infeed)
FZ Approach feed (infeed rate) (default: active feed rate)
E Reduced feed rate for circular elements (default: active
feed rate)
O Roughing or finishing—only for pocket milling
 0: Roughing
 1: Finishing
H Cutting direction
 0: Up-cut milling
 1: Climb milling
U Overlap factor (range: 0 < U < 1)
 No input: Contour milling
 U>0: Pocket milling—minimum overlap of milling paths
= U*milling diameter
JK Contour milling (input is evaluated only for contour milling)
 0: On the contour
 1: Within the contour
 2: Outside the contour
JT Pocket milling (input is evaluated only for pocket milling)
 0: From the inside out (from the inside towards the
outside)
 1: From the outside in (from the outside towards the
inside)
R Radius of approaching/departing arc (default: 0)
 R=0: Contour element is approached directly; infeed to
starting point above the milling plane—then vertical
plunge
 R>0: Tool moves on approaching/departing arc that
connects tangentially to the contour element
 R<0 for inside corners: Tool moves on approaching/
departing arc that connects tangentially to the contour
element
 R<0 for outside corners: Length of linear approaching/
departing element; contour element is approached/
departed tangentially
RB Retraction plane
SCI Safety clearance in the working plane
SCK Safety clearance in infeed direction (siehe Seite 142)
