Polar Coordinates, G15/G16

N5 G17 G90 X0 Y0
N10 G16 X100 Y45
N15 G91 X100 G90 Y0
N20 Y90
N25 G15
G15 Polar coordinate programming OFF
G16 Polar coordinate programming ON
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.
