3.3 Units – Milling in Y axis

ICP contour milling, XY plane unit

The unit mills the contour defined with ICP in the XY plane.
Unit name: G840_Kon_Y_Stirn / cycle: G840
Further information:
Contour form:
FK: ICP contour number
NS: Starting block no. of contour – beginning of contour
section
NE: Contour end block no. – end of contour section
Z1: Upper edge of milling
P2: Depth of contour
Cycle form:
JK: Cutter position
0: On the contour
1: Within/left of contour
2: Outside/right of contour
3: Depending on H and MD
H: Mill cutting direction
0: Up-cut
1: Climb
P: Maximum infeed
I: Contour-parallel oversize
K: Infeed-direction oversize
FZ: Approach feed (default: active feed rate)
E: Reduced feed
R: Approach radius
O: Plunging behavior (default: 0)
0: Straight – 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 with O = 1)
RB: Return plane (default: back to start position)
