G54 Work offsets G54 to G59
Mazak (EIA) G-code · Mill and lathe
Selects one of six work coordinate systems, G54 to G59. Program X Y Z values are then measured from that part zero. Mazak calls these work offsets in the EIA screens.
Format
G54 to G59
Addresses
| Address | What it does |
|---|---|
G54 to G59 | Work offset 1 to 6 |
How it works
Modal, group 12. G54 is the power on state.
Example program
G20 G17 G40 G49 G80 G90 (SAFETY LINE)
T01 M06 (TOOL 1)
G54 G00 X0. Y0. S3000 M03 (WORK OFFSET 1)
G43 H01 Z1. (LENGTH OFFSET)
T01 M06 (TOOL 1)
G54 G00 X0. Y0. S3000 M03 (WORK OFFSET 1)
G43 H01 Z1. (LENGTH OFFSET)
Example is in inch. Check offsets and clearances first.
Watch out for
- Mazatrol programs use their own work zero. An EIA program needs G54 to G59 set on the work offset screen.
- Call the offset before the first move in every tool, so a restart mid program is safe.
