Information
Only effective with the tool
radius compensation G41, G42
active
Inserts a rounding with the
specified radius value
tangentially between two
contour blocks
- Inserts roundings with the
specified radius value
tangentially
at the following contour corners;
special feedrate possible:
FRCM= ... - Modal rounding
OFF
Specification in degrees; angle
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
Specified in degrees; the thread
starting point with G33 will be
offset by the specified value
n =1,
axis identifier: e.g. "SP1" or "C"
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
SPOS and SPOSA have the
same functionality but differ in
their block change behavior:
With SPOS, the NC block is only
enabled once the position has
been reached.
With SPOSA, the block is
enabled even if the position has
not been reached.
