3. PRESSING FUNCTION
1 The following commands only are executable in nibbling
(i) X, Y positioning command by G00
Provided that the T code and F1–digit command can be
included in the same block where the X, Y positioning
is made by G00 to the first punch point of nibbling.
(ii) G26 (bolt hole circle), G76 (line at angle), G77 (arc),
G78, G79 (grid), G86 (share proofs), G87 (square), G88
(radius), G89 (cut at angle)
The movement amounts along the X–axis and Y–axis
to respective positioning points should not exceed the
parameter set value (Nos. 16188, 16189), except when
the first positioning point is equivalent to the first punch
point of nibbling.
(iii) G01, G02, G03, G41 and G42 commands.
2 The positioning distance commandable by the X–Y
positioning command by G00 is not composite distance
obtained by the movement amounts along
X–axis and Y–axis.
If the absolute value of the movement amount along either
X–axis or Y–axis exceeds the parameter set value (Nos.
16188, 16189), alarm (No. 4521) is issued.
This provision also applies to G26, G76, G77, G78, G79,
G86, G87, G88 and G89, correspondingly.
3 When offset was made by the tool diameter by G41 or G42
to G01, G02 and G03 as described, the offset straight line
or circular arc is divided by the pitch commanded by address
Be careful since the above division differs form such a case
that a commanded circular arc is divided by a commanded
pitch, like in G68 (circular nibbling).
Refer to parameter No.16181 to No. 16194 in the parameter manual
Series 16i/18i/160i/180i–PB OPERATOR’S MANUAL I–9.4 “Nibbling
