Simple longitudinal single-start thread G350
G350 cuts a longitudinal thread (internal or external thread). The thread
starts at the current tool position and ends at the end point Z.
Internal or external threads: See algebraic sign of "U."
Handwheel superposition (provided that your machine is equipped
accordingly): The superposition is limited to the following range:
X direction: Depending on the current cutting depth without
exceeding the starting and end points of the thread.
Z direction: Maximal 1 thread groove, without exceeding the
starting and end points of the thread.
Parameters
Z Corner point of thread
F Thread pitch
U Thread depth
U>0: Internal thread
U<0: External thread
U= +999 or –999: Thread depth is calculated
I Maximum infeed (no input: I is calculated from the thread
pitch and the thread depth)
Cycle stop becomes effective at the end of a thread
cut.
The feed rate and spindle speed overrides are not
effective during cycle run.
Handwheel superimpositioning can be activated with a
switch located on the machine operating panel if your
machine is equipped accordingly.
Feedforward control is switched off.
