G17 XY working plane
Siemens 840D 828D G-code · Mill and lathe
Selects the X Y plane for arcs, tool radius compensation and cycles. The tool axis is Z, so tool length acts in Z. G17 is the usual default on milling machines.
Format
G17
How it works
Modal, G group 6 (plane selection).
Example program
G17 G90 G54 ; XY PLANE
G0 X10 Y0 Z2 ; POSITION
G1 Z-1 F100
G2 X30 Y0 CR=10 F200 ; ARC IN XY PLANE
G0 X10 Y0 Z2 ; POSITION
G1 Z-1 F100
G2 X30 Y0 CR=10 F200 ; ARC IN XY PLANE
Example is in inch. Check offsets and clearances first.
Watch out for
- Change the plane only with tool radius compensation off (G40).
- Drilling and pocket cycles work in the active plane. A wrong plane drills along the wrong axis.
