Yes, all the offsets in the tool-table that have a matching axis are acted on.

While discussing the tool table I'll ask a question (it is too cold in the
shop to try it right now). Are all offsets (Z, X, Y) acted upon in a mill?
I'd like to use X/Y in the tool table to position an auxiliary spindle when
a special tool numbers that are in the auxiliary spindle are selected.

I'll certainly look into it, thanks Andy.

It would be the offset in the W axis. I doubt that you have a W axis,
so you won't see any effect, but the tool changer should be able to
read the value.

How about an entry in the W column of the tool table?

[Emc-users] Has anyone made use of a tool table entry in re a tool changer?

[Gene Heskett]

Greetings all;

One of the problems I'll have to solve in the future for a tool changer, 
is the diff in unlock run time of the ratchet wrench, dependent on 
whether the tool is in a TTS like holder, and all thats being changed is 
the TTS holder or needs to have the r9 itself changed, For the TTS, an 
unscrew of just enough to loosen the R8's grip on the TTS tool holder.

But if changing the r8 because the next tool is gooped at the correct 
length in an r8, I'll have to run the ratchet wrench another half an 
inch+ to totally drop the r8. This is also a lot more rise and fall of 
the z axis to achieve the clearance needed to move the chain. IOW I'll 
need to have two different canned motion sequences somehow controlled 
either by a tool table entry, or something to tell the tool changer what 
its to do.

How have the rest of you solved this problem on a smaller mill that might 
use both styles of tool holders? I could see a flag on the pocket 
tripping a microswitch, or at the expense of a longer chain, dedicated 
pockets, or a prox sw above the pocket that would trigger only on the 
longer r8? And probably something I haven't imagined yet.

Thanks for any suggestions I can carve into this when I find my lost 
round tuit.
