G16 Polar coordinates
Hurco WinMax (NC) G-code · Mill
Lets you give positions as radius and angle. In G17 the X word is the radius and the Y word is the angle in degrees from the current zero.
Format
G16 X Y [Z]
Addresses
| Address | What it does |
|---|---|
X | Radius in G17 |
Y | Angle in degrees in G17 |
Z | Normal Z move |
How it works
Modal, group 17. Cancel with G15.
Example program
T1 M06 (.250 DRILL)
G90 G54 G00 X0. Y0. S2500 M03 (BOLT CIRCLE CENTER)
G43 H01 Z1. M08 (LENGTH OFFSET)
G16 (POLAR ON)

The full 8-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- The first axis of the active plane is the radius and the second is the angle. Change plane and the letters change.
- Use it for bolt circles with a hole cycle.
