This cycle drills a hole on the lateral surface of the workpiece.
Cycle parameters
X, Z
Starting point
C Spindle angle (C-axis position)
X1 Start point drill (starting point of hole; default: drilling starts
from X)
X2 End point drill (end point of hole)
E Dwell time for chip breaking at end of hole
(default:0)
D Retraction type
 0: Rapid traverse
 1: Feed rate
AB Drilling lengths (default: 0)
V Through drilling variants (default: 0)
 0: No feed rate reduction
 1: Feed rate reduction at the end of the hole
 2: Feed rate reduction at the beginning of the hole
 3: Feed rate reduction at the beginning and end of the
hole
SCK Safety clearance (siehe Seite 142)
G14 Tool change point (siehe Seite 142)
T Turret pocket number
ID Tool ID number
S Spindle speed/cutting speed
F Feed per revolution
BP Break duration: Time span for interruption of the feed. The
chip is broken by the (intermittent) interruption of the feed.
BF Break duration: Time interval until the next break. The chip
is broken by the (intermittent) interruption of the feed.
MT M after T: M function that is executed after the tool call T.
MFS M at beginning: M function that is executed at the
beginning of the machining step.
MFE M at end: M function that is executed at the end of the
machining step.
WP Displays which workpiece spindle is used to process the
cycle (machine-dependent)
 Main drive
 Opposing spindle for rear-face machining
