(3) When the radius command is omitted
When the radius command is omitted, the zero point in the workpiece coordinate system is
applied to the polar coordinate center, and the distance between the polar coordinate center
and current position is regarded as the radius.
Note that the zero point in the local coordinate system is applied to the polar coordinate center
if the local coordinate system (G52) is used.

(4) When the angle command is omitted
When the angle command is omitted, the angle of the present position in the workpiece
coordinate system is applied to the angle command.
The zero point in the workpiece coordinate system is applied to the polar coordinate center by
commanding the radius with the absolute value. Note that the zero point in the local coordinate
system is applied to the polar coordinate center if the local coordinate system (G52) is used.
If the radius is commanded with the incremental value, the present position is applied to the
polar coordinate center.
