Circle center CC, radius and direction of rotation in the FC/FCT
block
The TNC calculates a circle center for free-programmed arcs from
the data you enter. This makes it possible to program full circles in
an FK program block.
If you wish to define the circle center in polar coordinates you must
use FPOL, not
CC
, to define the pole. FPOL is entered in Cartesian
coordinates and remains in effect until the control encounters a
block in which another
FPOL
is defined.
A circle center that was calculated or programmed
conventionally is then no longer valid as a pole or
circle center for the new FK contour: If you enter
conventional polar coordinates that refer to a pole
from a CC block you have defined previously, then
you must enter the pole again in a CC block after the
FK contour.
