Thread (general) G37–Geo
G37 defines the different types of thread. Multi-start threads and
concatenated threads are possible. Threads are concatenated by
programming several G01/G37 blocks after each other.
Parameter:
Q: Sort of thread (default: 1)
1: ISO fine DIN 13
2: ISO DIN 13
3: Taper DIN 158
4: Fine taper DIN 158
5: ISO trapezoid DIN 103
6: Trapezoid DIN 380
7: Sawing DIN 513
8: Round DIN 405
9: Cylindrical DIN 11
10: Taper DIN 2999
11: Pipe DIN 259
12: Not standardized
13: UNC US coarse
14: UNF US fine-pitch
15: UNEF US extra-fine-pitch
16: NPT US taper pipe
17: NPTF US Dryseal pipe
18: NPSC US pipe (with lubricant)
19: NPFS US pipe (without lubricant)
F: Thread pitch
Required for Q = 1, 3-7 , 12
For other thread types, F is calculated from the diameter if it
was not programmed
P: Thread depth (only with Q = 12)
K: End. length for threads without undercut (default: 0)
D: Reference pt. (default: 0)
0: Runout of thread at the end of the reference element
1: Runout of thread at the beginning of the reference
element
H: No.threads (default: 1)
A: Flank left – enter thread angle only for Q = 12
W: Flank right – thread angle at right (enter only for Q = 12)
R: Breadth (enter only for Q = 12)
E: Variable gr. (default: 0)
Increases/decreases the pitch per revolution by E.
V: Direction of thread:
0: Right-hand thread
1: Left-hand thread
