G02 Clockwise arc, Cartesian
Heidenhain TNC (ISO) G-code · Mill
Cuts a clockwise arc to the end point. Use the circle center I J from a previous block, or give the radius R. Klartext: C X Y DR- around CC, or CR X Y R DR-.
Format
G02 X Y [Z] [R] [F]
Addresses
| Address | What it does |
|---|---|
X Y | End point of the arc |
R | Arc radius, used instead of a circle center |
I J | Circle center, programmed in its own block before the arc |
F | Feed rate |
How it works
Modal path function.
Example program
N50 I+50 J+50 *
N60 X-40 Y+50 *
N70 G01 Z-5 F1000 M3 *
N80 G41 X+0 Y+50 F300 *

The full 9-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Without R the control uses the last circle center I J, so program the center block before the arc.
- A full circle needs the center I J and the same start and end point.
