Single thread cycle G32
G32 cuts a single thread in any desired direction and position
(longitudinal, tapered or transverse thread; internal or external
thread).
Parameters:
X: Final point (diameter value)
Z: Final point
XS: Starting diameter
ZS: Starting position Z
BD: Outside=0 / Inside=1 – external/internal thread
0: External thread
1: Internal thread
F: Thread pitch
U: Thread depth (default: no input)
Outside thread: U = 0.6134 * F1
Inside thread: U = –0.5413 * F1
I: Max. approach
IC: Number of cuts – the infeed is calculated from IC and U
Usable with:
V = 0: Constant chip cross section
V = 1: Constant infeed
V: Type of infeed
0: Const. mach. X-section
1: Const. infeed
2: EPL with distrib. of cuts
3: EPL w/o distrib. of cuts
4: MANUALplus 4110
5: Constant infeed (4290)
6: Const. w/ distrib. (4290)
H: Type of offset for smoothing the thread flanks (default: 0)
0: Without offset
1: From left
2: From right
3: Alternating left/right
WE: Lift off method with K=0 (default: 0)
0: G0 at end
1: Lift-off in thread
K: Thread runout length at thread end point (default: 0)
W: Taper angle (range: –45° < W < 45°)
Position of the taper thread with respect to longitudinal or
transverse axis:
W > 0: Rising contour (in machining direction)
W < 0: Falling contour
C: Start angle
A: Approach ang. (range: –60° < A < 60°; default: 30°)
