Motion commands
4.16 Linear progressive/degressive thread pitch change (G34, G35)
Fundamentals
Programming Manual, 11/2006, 6FC5398-1BP10-2BA0
173
Note
DITE acts at the end of the thread as an approximate distance. This achieves a smooth
change in the axis movement.
When a block containing command DITS and/or DITE is loaded to the interpolator, the path
programmed in DITS is transferred to SD 42010: THREAD_RAMP_DISP[0] and the path
programmed in DITE to SD 42010 THREAD_RAMP_DISP[1].
The programmed run-in path is handled according to the current setting (inches, metric).
4.16 Linear progressive/degressive thread pitch change (G34, G35)
Function
You can use the functions G34/G35 to produce self-cutting threads.
Both the functions G34 and G35 offer the functionality of G33, but provide the additional
option of programming a pitch change under F.
Programming
G34 X… Y… Z… I… J… K… F…

Parameters
G34
Progressive change in thread lead (tapping with linear pitch increase)
G35
Degressive change in thread lead (tapping with linear pitch decrease)
X Y Z
End point in Cartesian coordinates
I
Thread pitch in X direction
