Circular path CP around pole CC
Application
You use the circular path function CP to program a circular path around the defined pole.
Related topics
- Programming a circular path with Cartesian coordinates
Requirement
- Pole CC
You must define a pole CC before programming with polar coordinates.
Description of function
The control moves the tool on a circular path from the current position to the defined end point. The starting point is the end point of the preceding NC block.
The distance from the starting point to the pole is automatically both the polar coordinate radius PR as well as the radius of the circular path. You define the polar coordinate angle PA that the control moves to with this radius.
Input
11 CP PA+50 Z-2 DR- RL F250 M3 | ; Circular path |

The NC function includes the following syntax elements:
Syntax element | Meaning |
---|---|
CP | Syntax initiator for a circular path around a pole |
PA | Polar coordinate angle Entry: absolute or incremental Optional syntax element |
X, Y, Z, A, B, C, U, V, W | Axis and value of the linear superimposition Entry: absolute or incremental Linear superimpositioning of a circular path Optional syntax element |
DR | Rotational direction of the arc Optional syntax element |
R0, RL, RR | |
F, FMAX, FZ, FU, FAUTO | |
M |
Notes
- The Form column allows toggling between the syntaxes for Cartesian and polar coordinate input.
- If you define PA incrementally, you must define the direction of rotation with the same algebraic sign.
Consider this behavior when importing NC programs from earlier controls, and adapt the NC programs if necessary.
