Circle center CC

You can define a circle center for circles that you program with the C
key (circular path C). This is done in the following ways:
Enter the Cartesian coordinates of the circle center in the working
plane, or
Use the position last programmed, or
Take over the coordinates with the Actual-position-capture key
Enter coordinates for the circle center or, if you
want to use the last programmed position, enter
no coordinates
5 CC X+25 Y+25
or
10 L X+25 Y+25
11 CC
The program blocks 10 and 11do not refer to the
illustration.
Validity
The circle center definition remains in effect until you program a new
circle center.
Entering the circle center 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.
