SON
Nibbling ON
SON activates the nibbling function and deselects the other functions in G group35 (e.g. PON).
In contrast to punching, the first stroke is made at the start point of the block with the
activating command, i.e. before the first machine motion.
SON has a modal action, i.e. it remains active until either SPOF or PON is programmed or until
the program end is reached.
The stroke initiation is suppressed in blocks without traversing information relating to the
axes designated as punching or nibbling axes (typically those in the active plane). If a stroke
still needs to be initiated, then one of the punching/nibbling axes must be programmed with a
0 traversing path. If the first block with
SON is a block without traversing information of the
type mentioned, then only one stroke takes place in this block since the start and end points
are identical.
Programming example:
Program code Comment
:
:
N70 X50 SPOF ; position without punch initiation
N80 X100 SON ; Activate nibbling, initiate a stroke before the
; motion (X=50) and on completion of the programmed
; movement (X=100)

SONS
Nibbling ON (in position control cycle)
SONS behaves in the same way as SON. The function is activated in the position control cycle,
thus allowing time-optimized stroke initiation and an increase in the punching rate per
minute.
PON
Punching ON
PON activates the punching function and deactivates SON.
PON has a modal action like SON.
In contrast to
SON, however, a stroke is not executed until the end of the block or, in the case
of automatic path segmentation, at the end of a path segment. PON has an identical action
to
SON in the case of blocks which contain no traversing information.
