. . .
N1 T5 G97 S1100 G95 F0.5 M3
N2 G0 X101.84 Z5
N3 G33 X120 Z-80 F1.5 P0
Thread single path
N4 G33 X140 Z-122.5 F1.5
N5 G0 X144

Cycle run:
1
Accelerates to feed rate (line B)
2
Moves at feed rate to Final point of thread – Overflow length P
3
Decelerates (line P) and remains at Final point of thread
Activating handwheel during G33
With the G923 code, you can activate the handwheel in order to
make compensations during a thread cut. In the G923 code, you
define limits within which traverse with the handwheel is possible.
Parameters:
X: Max. positive offset – limit in +X
Z: Max. positive offset – limit in +Z
U: Max. negative offset – limit in -X
W: Max. negative offset – limit in -Z
H: Ref. direction
H = 0: Longitudinal thread
H = 1: Transverse thread
Q: Sort of thread
Q = 1: Right-hand thread
Q = 2: Left-hand thread
