10.1 Fundamental Principles of NC Programming
Address Meaning
RND Rounding
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
machining step
STARTFIFO Start of fast
machining step
STOPRE Preprocessing stop
TRAFOOF Switch off TRAANG
TRAANG Inclined axis

Value assignments Information
0.010 ... 99 Inserts a rounding with the
999.999 specified radius value
tangentially between two
contour blocks
0.010 ... 99 - Inserts roundings with the
999.999 specified radius value
tangentially at the following
contour corners; special
0 feedrate possible: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:
according 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
spindle stops at the specified
position (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.

transformations
