G02 Circular move clockwise
Mitsubishi M70 M80 G-code · Mill
Cuts a clockwise arc in the selected plane using R or I J K. Adding a third axis gives a helical move.
Format
G02 X Y [Z] R or I J [K] F
Addresses
| Address | What it does |
|---|---|
X Y Z | End point of the arc |
R | Arc radius |
I J K | Distance from start point to arc center, always incremental |
F | Feed rate |
How it works
Modal, group 01.
Example program
G00 X1. Y0. (START OF CIRCLE)
G01 Z-.1 F8. (FEED TO DEPTH)
G02 I-1. J0. F15. (FULL CIRCLE 2.0 DIA)
G00 Z.1 (CLEAR)
G01 Z-.1 F8. (FEED TO DEPTH)
G02 I-1. J0. F15. (FULL CIRCLE 2.0 DIA)
G00 Z.1 (CLEAR)
Example is in inch. Check offsets and clearances first.
Watch out for
- I J K are incremental from the start point even in G90.
- R cannot cut a full circle. Use I and J for a full 360 degree circle.
- Clockwise is seen looking from the plus end of the axis normal to the plane.
