Data type Meaning
13 <_VARI> INT Machining type
UNITS: Reserved
TENS: Swarf removal before thread milling
0 = No chip removal before thread
milling (only active at final drilling
depth)
1 = Chip removal before thread mill‐
ing (only active at final drilling
depth)
HUNDREDS: Right-hand/left-hand threads
0 = Right-hand thread
1 = Left-hand thread
THOUSANDS: Remaining drilling depth with drilling fee‐
drate
0 = No remaining drilling depth with
drilling feedrate FR
1 = Remaining drilling depth with drill‐
ing feedrate FR
TEN THOUSANDS: Predrilling with reduced feedrate
0 = No predrilling with reduced fee‐
drate
1 = Predrilling with reduced feedrate
Predrilling feedrate = 0.3 F1, if
F1 < 0.15 mm/rev
Predrilling feedrate = 0.1 mm/rev,
if F1 ≥ 0.15 mm/rev
14 <_CDIR> INT Milling direction 0 = Down-cut
1 = Up-cut
4 = Up-cut + down-cut (combined
roughing + finishing)
15 Z2 <_GE> REAL Retraction distance before thread milling (inc)
16 F1 <_FFD> REAL Drilling feedrate (mm/min or in/min or mm/rev)
17 FR <_FRDP> REAL Drilling feedrate for remaining drilling depth (mm/min or mm/rev)
18 F2 <_FFR> REAL Feedrate for thread milling (mm/min or mm/tooth)
19 FS <_FFP2> REAL Finishing feedrate for <_CDIR> =4 (mm/min or mm/tooth)
20 <_FFA> INT Evaluation of feedrates
UNITS: Drilling feed F1
TENS: Drilling feedrate for remaining drilling
depth FR
HUNDREDS: Feedrate for thread milling F2
THOUSANDS: Finishing feedrate FS
21 <_PITM> STRING[15] String as marker for pitch input (for the interface only)
1)
22 <_PTAB> STRING[20] String for thread table ("", "ISO", "BSW", "BSP", "UNC") (for the interface
only)
1)
23 <_PTABA> STRING[20] String for selection from thread table (e.g. "M 10", "M 12", ...) (for the
interface only)
1)
