The repeat cutting can be made by the rotation of a figure commanded
with a sub program using the following commands :
Select the plane on which rotational copy will be performed, using plane
selection commands G17, G18, and G19.
G17 G72.1 P_ L_ Xp_ Yp_ R_ ;
P : Sub program number
L : Number of repetitions
Xp : Xp axis center coordinate of rotation
(Xp : X axis or the axis which is parallel to X axis)
Yp : Yp axis center coordinate of rotation
(Yp : Y axis or the axis which is parallel to Y axis)
Zp : Zp axis center coordinate of rotation
(Zp : Z axis or the axis which is parallel to Z axis)
R : Rotation angle (+ = Counterclockwise direction)
