Simple thread cycle G32
G32 cuts a simple thread in any desired direction and position (longitu-
dinal, tapered or transverse thread; internal or external thread). G32
calculates the thread to be cut from the ”thread end point,” ”thread
depth” and the current tool position.
Parameters
X, Z: End point of thread (X diameter)
F:
Thread pitch
P: Thread depth
I: Cutting depth
B: Remainder cut – default: 0
■ B=0: division of the last cut into 1/2, 1/4, 1/8, 1/8 cut.
■ B=1: no remaining cut division
Q: Number of air cuts after the last cut – default: 0
K: Runout length – default: 0 (see G33)
W: Taper angle (range: –45° < W < 45°) – default: 0; position of the
taper thread with reference to longitudinal or transverse axis.
■ W>0: Rising contour (in machining direction)
■ W<0: Falling contour
C: Starting angle – default: 0
H: Type of offset – default: 0
■ H=0: no offset
■ H=1: offset to the left
■ H=2: offset to the right
■ H=3: offset alternating left and right

• ”Feed rate stop” becomes effective only
at the end of a thread cut.
• Feed rate override is not effective.
• Spindle override is not effective.
• Create thread with G95 (feed rate per
revolution).
• Look-ahead control is switched off.
