G00 Rapid positioning
Swiss (Citizen Star) G-code · Lathe
Moves the tool or the sliding headstock at rapid rate to the end point. On a Swiss lathe the Z move is the headstock and bar moving, not the tool.
Format
G00 X Z [Y] [C]
Addresses
| Address | What it does |
|---|---|
X Z | End point. X is diameter |
Y | Cross slide Y on gang tool machines |
C | Spindle C axis position |
How it works
Modal, group 01. Stays on until G01, G02, G03 or a cycle.
Example program
G00 X.55 Z-.02 T0100 (RAPID TO START, TOOL 1)
G01 X-.02 F.001 (FACE)
G00 X.55 (CLEAR IN X FIRST)
Z0. (BAR BACK TO ZERO)
G01 X-.02 F.001 (FACE)
G00 X.55 (CLEAR IN X FIRST)
Z0. (BAR BACK TO ZERO)
Example is in inch. Check offsets and clearances first.
Watch out for
- Z is the bar moving through the guide bushing. A rapid in minus Z pulls the part back toward the bushing, so clear the tool in X first.
- Gang tools sit side by side. Retract X far enough to clear the next tool on the slide before moving Y.
