ICP predrilling, pocket milling, YZ plane unit
The unit determines the hole position and machines the hole.
The subsequent milling cycle obtains the hole position from the
reference stored in NF. If the pocket consists of multiple sections,
the unit machines a hole for each section.
Unit name: DRILL_MAN_845_Y / cycles: G845 A1

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
X1: Upper edge of milling
P2: Depth of contour
Cycle form:
JT: Machining direction
0: From the inside out
1: From the outside in
H: Mill cutting direction
0: Up-cut
1: Climb
I: Contour-parallel oversize
K: Infeed-direction oversize
U: Overlap factor – defines the overlap of milling paths (default:
0.5) (range: 0 to 0.99)
Overlap = U * milling diameter
WB: Milling diameter
NF: Position mark – reference at which the cycle stores the
hole positions (range: 1 to 127)
E: Period of dwell at end of hole (default: 0)
D: Retraction type
0: Rapid traverse
1: Feed rate
V: Feed reduction
0: Without reduction
1: At end of the hole
2: At start of the hole
3: At start & end of hole
AB: Drilling lengths (default: 0)
RB: Return plane (default: back to start position)
