G19 YZ plane selection
Haas NGC G-code · Mill, Lathe
On mills: YZ plane selection
Selects the YZ plane for arcs and cutter compensation. Arcs use J and K.
Format
G19
How it works
Modal, plane group 02.
Example program
G19 (YZ PLANE)
G03 Y1. Z-.5 J.5 K0. F10. (ARC IN YZ)
G17 (BACK TO XY PLANE)
G03 Y1. Z-.5 J.5 K0. F10. (ARC IN YZ)
G17 (BACK TO XY PLANE)
Example is in inch. Check offsets and clearances first.
Watch out for
- Return to G17 when done so later arcs and cycles are not in the wrong plane.
On lathes: YZ plane selection
Selects the YZ plane for arcs and cutter comp. Used for side milling with a radial live tool on a Y axis lathe, and with G107.
Format
G19
How it works
Modal, group 02.
Example program
T1212 (RADIAL END MILL, LIVE TOOL)
G19 (YZ PLANE)
G98 (FEED PER MINUTE)
G02 Y.25 Z-.75 R.25 (ARC IN YZ PLANE)

The full 5-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- G107 cylindrical mapping should only be used in G19.
- Return to G18 before turning.
