G53 Machine coordinate positioning
Mazak (EIA) G-code · Mill and lathe
Moves to a position in machine coordinates for that block only, ignoring work offsets. Used for tool change, tool setter and park positions.
Format
G53 X Y Z
Addresses
| Address | What it does |
|---|---|
X Y Z | Position in machine coordinates |
How it works
Non-modal. Only acts in its own block.
Example program
G00 Z1. M09 (RETRACT)
G49 (LENGTH OFFSET OFF)
G53 Z0. (Z TO MACHINE ZERO)
G53 X-20. Y0. (PARK THE TABLE)
G49 (LENGTH OFFSET OFF)
G53 Z0. (Z TO MACHINE ZERO)
G53 X-20. Y0. (PARK THE TABLE)
Example is in inch. Check offsets and clearances first.
Watch out for
- Use absolute values. G53 with G91 is ignored or alarms.
- Tool length offset should be cancelled first or the Z position includes it.
