Circle center CC
You can define a circle center CC for circles that are programmed with
the C key (circular path C). This is done in the following ways:
n
Entering the Cartesian coordinates of the circle center, or
n
Using the circle center defined in an earlier block, or
n
Capturing the coordinates with the ACTUAL-POSITION-CAPTURE
key.
U
Coordinates
CC: Enter the circle center coordinates,
or
If you want to use the last programmed position, do
not enter any coordinates.
Example NC blocks
or
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. You can also define a circle center for the secondary
axes U, V and W.
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.
5 CC X+25 Y+25
10 L X+25 Y+25
11 CC
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.
