G25, what is it?

[Randy]

What is G25 on a Fanuc 0MC control? it's on the screen as an active
command but it's not in my Fanuc manual.

Thank You,
Randy

If FANUC is sticking with their standard, G25 is spindle speed fluctuation
detection = off

Oh yeah, the normal power on default is G26 which enables the function.

interesting, mine seems to default to G25 "off"

Maybe this is why I break taps? but then again I can do 4-40, 6-32,
8-32 and 10-32 just fine. it only likes to break 1/4-20's

Thank You,

Hang in there Randy. Eventually you will be able to break any size tap
reliably.
LOL
Seriously though, if there are no outside mechanical influences, the timing
and synchronization constants can be adjusted to give you reliable tapping.
The MTB might even be able to have a tech stop by and do it.
