Simple longitudinal single-start thread G350 – 4110
G350 cuts a longitudinal thread (internal or external thread). The
thread starts at the current tool position and ends at the Final point
Z.
Parameters:
Z: Edge of thread
F: Thread pitch
U: Thread depth
U > 0: Internal thread
U <= 0: External thread (lateral surface or front face)
U = +999 or –999: Thread depth is calculated
I: Max. approach (no input: I is calculated from the thread pitch
and the thread depth)
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
NC 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.
