A dowel pin works great for this - very precise, and you can simply
push it against the side of the tool, then raise the tool (or lower

Igor,
The whole point of tool length offsets is to run the program as if all
tools are the same length. Early NC machines had the tool length
incorporated in the program and the operator had to match each tool length
to the programmed tool length for each tool. There were elaborate tool
holders
Stuart, thanks. Great explanation. I already set up a little tool table.
One more question, is, once I set up the tool table, how to set the
initial offset so that the first tool chosen in the program, would be
properly adjusted for height. Should I select my first tool in MDI
(say M6T2), and

Don't forget the G43...

Show off your parallel
the g43 is the important part
you need to turn on the tool length offset for the tool in the spindle and
then the tool will be able to set the work piece coordinate zero

Got it.
Do in MDI:
M6 T2 G43
(then set height using a sliding gage block)
(then set Z=zero)
(then start program that again asks for T2.)

For tool measurements off the taper of the holder, for cat 40 and cat 50 at
least it should be easy to even purchase blocks to use on the surface plate
with a height gage. Every place I worked at had some, so I never had to
source out.
If this is available for your tool holders it provides nice

Guys,
First off, thanks to all for porting EMC to 10.04, it is fantastic.
Just a question. I use quick change toolholders based on NMTB-30.
I am trying to get a tool table started. And I wonder if I can simply
measure the total length of the tool, in toolholder, with a caliper,
and then
you can use the measured tool length as the number in the tool table
you will need to set your z zero to use the measured tool length

What do you use to locate Z edge of a part?
You cannot use a ball end electronic edge finder, right?

I do use the zero tool. Usually I use a carbide end mill as a feeler. As
mentioned earlier, bring tool zero down to just above the work piece,

My hideous technique is to lower the tool close to the part, then feel

What I am doing now is setting up a tool table using GUI.
I first homed the mill. Then I would load one tool after another: for
each of them, I would find the Z coordinate so that they barely clear
a gage block. Then, I enter the minus of that as Z attribute of the
tool.
