Axis Motion
Chapter 14
14-26
It is possible t o change from incremental to absolute or absolute to
incremental modes during polar programming if desired. The axis word is
interpreted by the control in the mode that it was specified in. Mixed
combinations such as angles designated in absolute and radii designated in
incremental are possible.
Example 14.10 is used to illustrate this.

When programming an arc using polar programming the angle and radius
values still define the e nd point of the next move. The center point of the
arc must still be designated in the circular block using either the I, J, or K
words or by designating a radius value (see the section 14.1.3 on
circular interpolation).
