Fagor 8055 8065 G-code · Mill
Applies tool length from the offset selected with D, or the tool table, on the longitudinal axis. Comp starts when that axis moves.
Format
G43
Addresses
| Address | What it does |
|---|---|
None | Length comes from the D offset or the tool table |
How it works
Modal. Cancel with G44 or G74. A parameter decides if reset cancels it.
Example program
T1 D1 M06 (TOOL 1 OFFSET 1)
G00 G90 G54 X1.0 Y1.0 S2000 M03 (POSITION XY)
G43 Z1.0 (LENGTH COMP ON AS Z MOVES)
G01 Z-0.25 F10.0 (CUT)
G00 G90 G54 X1.0 Y1.0 S2000 M03 (POSITION XY)
G43 Z1.0 (LENGTH COMP ON AS Z MOVES)
G01 Z-0.25 F10.0 (CUT)
Example is in inch. Check offsets and clearances first.
Watch out for
- Fagor has no H word. The length comes from the D offset.
- G43 in or before the canned cycle block. Position outside the part first.
- G53 cancels length comp for its block only.
