Example of cylinder coordinates
The 3rd geometry axis, which lies perpendicular to the working plane, can also be specified
in Cartesian coordinates.
This enables spatial parameters to be programmed in cylindrical coordinates.
Example: G17 G0 AP... RP... Z...
Traversing commands
The positions stated with polar coordinates can be approached with rapid traverse G0, linear
interpolation G1, circular interpolation clockwise G2 or counterclockwise G3.
Working plane
The polar coordinates are valid in the working plane selected with G17 to G19.
You must not program Cartesian coordinates, such as interpolation parameters or axis
addresses, for the selected working plane in NC blocks with polar end position coordinates.
Polar angle AP
When absolute dimensions are specified, the angular reference is based on the horizontal
axis of the working plane, e.g., X axis with G17. The positive direction of rotation is counter-
clockwise.
