I Programming
Of course, the polar coordinate command mode is cancelled by G15, and then is specified again by
G16 and the new polar position is set.
Axes commands that are not considered as polar coordinate commands
In the polar coordinate mode, the following specified axes are not considered as the polar coordinate
command. Moreover, the axes other than the first and the second axes on the selected plane are not
considered as the polar coordinate command.

Limitations
z In the polar coordinate mode, specify a radius for circular interpolation or helical cutting (G02, G03)
with R.
z In the polar coordinate mode, no chamfer function can be specified.
z Cylinder interpolation mode cannot be specified in polar coordinate mode.
Cancel the polar coordinate mode
