Circle center CC
You can define a circle center CC for circles that are programmed
with the C soft key (circular path C). This is done in the following
ways:
■ Entering the Cartesian coordinates of the circle center
■ Using the circle center defined in an earlier block
■ Capturing the coordinates with the
„ACTUAL POSITION“ soft key
ú Select circle functions: Press the „CIRCLE“ soft key
(2nd soft-key row)
ú Coordinates CC: Enter the circle center coordinates
If you want to use the last programmed position,
do not enter any coordinates.
Example NC blocks
5 CC X+25 Y+25
or
10 L X+25 Y+25
11 CC
The program blocks 10 and 11 do not refer to the illustration.
Duration of effect
The circle center definition remains in effect until a new circle
center is programmed.
Entering the circle center CC incrementally
If you enter the circle center with incremental coordinates, you
have programmed it relative to the last programmed position of the
tool.
The only effect of CC is to define a position as circle
center: The tool does not move to this position.
The circle center is also the pole for polar coordinates.
