Threadcut cycle group
Metric ISO thread G35
With G35, you can cut internal and external longitudinal threads. From
the tool position relative to the final point of the thread, MANUALplus
automatically determines whether an internal or external thread is to be
cut.
Parameters
X, Z:
End point of thread (X diameter)
F: Thread pitch – default: value from standard table
I: Maximum infeed – default: I is calculated from the thread pitch
and the speed
Q: Number of air cuts after the last cut – default: 0
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
• “Cycle STOP” only becomes effective at the end of a thread cut.
• The feed rate and spindle speed overrides are disabled during
execution of the cycle.
• If you are programming an internal thread, it is advisable to
preset “F” since the diameter of the longitudinal element is not
the thread diameter. If you have MANUALplus calculate the
thread pitch automatically, slight deviations may occur.
