Programming
3.1 Fundamental Principles of NC Programming
Address Meaning
RNDM Modal rounding
RPL Angle of rotation with
ROT, AROT
SET( , , , ) Set values for the
variable fields
REP()
SETMS(n) Define spindle as
SETMS master spindle
SF Thread starting point
when using G33
SPI(n) converts the spindle
number n into the
axis identifier
SPOS spindle position
SPOS(n)
STOPFIFO Stops the fast ma-
chining step
STARTFIFO Start of fast machin-
ing step
STOPRE Preprocessing stop
TRAFOOF Switch off TRAANG
TRAANG Inclined axis trans-
formation
G05 Activates oblique
plunge-cutting
G07 Approach starting
position
3-16
Value assignments Information
0.010 ... 99 - Inserts roundings with the
999.999 specified radius value tangen-
tially at the following contour
corners; special feedrate possi-
0 ble:FRCM= ...
- Modal rounding OFF
±0.00001 ... Specification in degrees; angle
359.9999 for a programmable rotation in
the current plane G17 to G19
SET: Various values, from the
specified element up to: accord-
ing to the number of values
REP: the same value, from the
specified element up to the end
of the field
n= 1 or n= 2 n: Number of the spindle,
if only SETMS is set, the default
master spindle comes into
effect
0.001 ... 359.999 Specified in degrees; the thread
starting point with G33 will be
offset by the specified value
n =1 or =2,
axis identifier: e.g. "SP1" or "C"
0.0000 ... 359.9999 specified in degrees; the spin-
dle stops at the specified posi-
tion (to achieve this, the spindle
must provide the appropriate
technical prerequisites: position
control)
Spindle number n: 1 or 2
Special function;
filling of the buffer memory until
STARTFIFO, "Buffer memory
full" or "End of program" is
detected.
Special function;
the buffer memory is filled at the
same time.
Special function; the next block
is only decoded if the block
before STOPRE is completed.
- Disables all kinematic transfor-
mations
Can only be set with inclined
axis (TRAANG)
Can only be set with inclined
axis (TRAANG)
