X Polar radius
Y Polar angle
G90 The pole lies in the workpiece zero point
G91 The pole lies in the current position
no X in block The pole lies in the workpiece zero point
The pole radius is always traversed absolute; the polar
angle can be traversed either absolute or incremental.
Note
If the pole is moved from the current position to the
workpiece zero point, the radius is calculated as distance
between the positions.
