G16
Between G16 and G15 points can be defined by polar coordinates.
The selection of the plane in which polar coordinates can be programmed occurs with G17 – G19.
With the address of the first axis the radius will be programmed,
with the address of the second axis the angle will be programmed,
both related to the workpiece zero point.
Example

N75 G17 G16 N80 G01 X50 Z30 first axis: radius X=50 second axis: angle Y=30
