G02 Circular interpolation clockwise

Brother Speedio G-code · Mill

Cuts a clockwise arc in the selected plane. Give the arc end point and either the radius R or the center offsets I J K.

Format

G02 X Y [Z] R F or G02 X Y I J F

Addresses

Address	What it does
`X Y Z`	Arc end point
`R`	Arc radius
`I J K`	Distance from start point to arc center on X Y Z
`F`	Feed rate

How it works

Modal, motion group.

Example program

G00 X1. Y0 (ARC START)
G01 Z-.1 F10. (FEED DOWN)
G02 X0 Y-1. R1. F20. (90 DEGREE CW ARC)
G02 X0 Y-1. I0 J1. (FULL CIRCLE WITH I J)
…

The full 5-line example is in the app. Example is in inch. Check offsets and clearances first.

Watch out for

A full circle needs I and J. R cannot make a full circle.
Direction is seen looking down the axis that is normal to the active plane.
