Example of turning
The traverse paths are entered in absolute coordinates with reference to the workpiece zero.
For entering the circle center point coordinates I and J see circle interpolation G2/G3.

Description
The dimensions refer to the origin of the active coordinate system. You program the point to
which the tool is to travel, e.g., in the workpiece coordinate system.
Non-modal absolute dimensioning AC
When incremental dimension G91 is active, AC can be used to allow entry of absolute
dimensions for individual axes on a block-by-block basis.
