axis | Letter of the new longitudinal axis |
How it works
Modal until G15, G16, G17, G18 or G19 is programmed.
Example program
G17 (XY PLANE, LENGTH COMP ON Z)
G15 W (LENGTH COMP ON W QUILL)
G43 G00 W1.0 (COMP APPLIES WHEN W MOVES)
G15 W (LENGTH COMP ON W QUILL)
G43 G00 W1.0 (COMP APPLIES WHEN W MOVES)
Example is in inch. Check offsets and clearances first.
Watch out for
- Programming G17, G18 or G19 again puts length comp back on the perpendicular axis.
- On 8055 T lathes G15 has another use for the C axis. Check that manual.
