Programming technological functions (cycles)
10.1 Drilling
Parameter Description
Thread Direction of rotation of the thread
● Right-hand thread
● Left-hand thread
(only in mode "without compensating chuck")
Selection Selection of table value: e.g.
● M3; M10; etc. (ISO metric)
● W3/4; etc. (Whitworth BSW)
● G3/4; etc. (Whitworth BSP)
● 1" - 8 UNC; etc. (UNC)
P Pitch ...
● In MODULUS: MODULUS = Pitch/π
● In turns per inch: Used with pipe threads, for example.
● In mm/rev
● In inch/rev
The pitch is determined by the tool being used.
S Spindle speed - (only for tapping without compensating chuck).
Machining (not The following machining operations can be selected:
for "with compen‐
● One cut
sating chuck")
● Chip breaking
● Swarf removal
D 1st drilling depth (abs) or 1st drilling depth referred to Z0 (inc)
SR Spindle speed for retraction - (only for "without compensating chuck").
Hidden parameters
The following parameters are hidden. They are pre-assigned fixed values or values that can
be adjusted using setting data.
Parameter Description
PL Machining plane
SC Safety clearance
Table Thread table selection
αS Starting angle offset
Retraction Without retraction distance after each machining step - (for
chip breaking only)
DT Dwell time at final drilling depth
SDE Direction of rotation after end of cycle

When entered per inch, enter the integer number in front of the decimal point in the
first parameter field and the figures after the decimal point as a fraction in the second
and third field.
The thread is drilled in one cut without interruption.
The drill is retracted by the retraction amount V2 for chip breaking.
The drill is retracted from the workpiece for swarf removal.
