SINUMERIK 802D sl Operation and Programming Nibbling (BP-N), 06/2006 Edition
6FC5 398-3CP10-0BA0
SPOF Punching and nibbling OFF
The SPOF function terminates all punching and nibbling functions. In this state, the NCK re-
sponds neither to the “Stroke active” signal nor to the PLC signals specific to punching and
nibbling functions.
If SPOF is programmed together with a travel command in one block (and in all further
blocks, if punching/nibbling is not activated with SON or PON), the machine approaches the
programmed position without the initiation of a punching operation. SPOF deselects SON,
SONS, PON and PONS and is equivalent to a RESET state.
Programming example for SPOF
N20 G90 X100 SON ; Activate punching
N25 X50 SPOF ; Deactivate punching; positioning without stroke initiation
SON Nibbling ON
SON activates the nibbling function and deselects the other functions in G group 35 (e. g.
PON).
In contrast to punching, the first stroke is made at the starting point of the block with the acti-
vating command, i. e. before the first machine motion is performed.
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
nevertheless is to be initiated, then one of the punching/nibbling axes must be programmed
with 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 for SON
;
N70 X50 SPOF ; Positioning without punching initiation
N80 X100 SON ; Activate nibbling; stroke initiation before the
motion (X=50) is started and at the end of the programmed
motion (X=100)
SONS Nibbling ON (in the position controller 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.
