Data type Meaning
14 <_VARI> INT Machining type
UNITS: Technology
1 = External thread with linear infeed
2 = Internal thread with linear infeed
3 = External thread with degressive
infeed, cross-section of cut re‐
mains constant
4 = Internal thread with degressive
infeed, cross-section of cut re‐
mains constant
TENS: Reserved
HUNDREDS: Infeed type
1 = Infeed on one side
2 = Infeed alternate sides
THOUSANDS: Reserved
TEN THOUSANDS: Alternative depth infeed
0 = Preset number of roughing cuts
(<_NRC>)
1 = Preset value for 1st infeed
(<_MID>)
HUNDRED THOUSANDS: Machining type
1 = Roughing
2 = Finishing
3 = Roughing and finishing
ONE MILLION: Machining sequence for multistart thread
0 = In ascending order of threads
1 = In descending order of threads
15 N <_NUMTH> INT Number of thread turns
16 VR <_SDIS> REAL Return distance, inc
17 D1 <_MID> REAL First infeed depth, in conjunction with <_VARI> (TEN THOUSANDS)
18 DA <_GDEP> REAL Thread changeover depth (only effective with "multiple start")
0 = Do not observe any thread
changeover depth
> 0 = Observe thread changeover
depth
19 G <_PIT1> REAL Change of pitch per revolution
0 = Pitch is constant (G33)
> 0 = Pitch increases (G34)
< 0 = Pitch decreases (G35)
20 <_FDEP> REAL Insertion depth (enter without sign)
21 N1 <_GST> INT Starting thread N1 = 1...N, in conjunction with <_AMODE> (HUNDRED
THOUSANDS)
22 <_GUD> INT Reserved
23 <_IFLANK> REAL Infeed slope as width (for interface only)
