Fagor 8055 8065 G-code · Mill, Lathe
On mills: Constant feed at cutting point (mill)
On Fagor mills G96 keeps F at the cutting edge on arcs when radius comp is on. It is not constant surface speed.

How it works
Modal. Replaced by G97, which keeps F at the tool center.
Example program
G96 (FEED AT THE CUTTING EDGE)
G03 X2.0 Y2.0 R1.0 (INSIDE ARC AT TRUE FEED)
G97 (FEED AT TOOL CENTER)
Example is in inch. Check offsets and clearances first.
Watch out for
- On the 8055 M, G96 is feed control, not spindle speed control.
- Use with G41 or G42 for accurate feed on inside arcs.
On lathes: Constant surface speed (lathe)
Spindle speed changes with diameter to keep S as surface speed, in feet per minute with G70 or meters per minute with G71.
Verify on your machine. This entry could not be fully checked against the maker manual. Check your machine manual before you run it.

Watch out for
- Set G92 S as a speed limit first.
- On Fagor mills G96 is a feed control, not surface speed.
