I toyed around with the idea and asked questions about indexable
tooling here two years ago when I first got my 7" X 14" lathe, and I
have decided to become more serious about it.

What I really wanted to start with was the 16N, but there is no cigar
for second place: http://cgi.ebay.com/ws/eBayISAPI.dll...m=250227734204
(If it wasn't for the high bidder, I would have paid just over $60 for
it). :-(

The 16N tends to go so high that you might as well buy them new from
the manufacturer. There was one several months ago with a $60 Buy-It-
Now, but some genius decided to try to get it cheaper than that before
I could get to the auction.(Needless tosay, it went for a lot more
than $60).

Anyway, since most of my machining links went with the big PC crash of
2006, I was hoping that someone could direct me to some sites that
explain the characteristics and features of various indexable tooling.

My MSC catalog is two years old and I see stuff on their website that
is new to me.(however, I did win a 12N:
http://cgi.ebay.com/ws/eBayISAPI.dll...m=250227383836)

I just have to learn more about it. :-)

Thanks a lot.

Have you looked through their catalog? Link above.

I downloaded that catalog a week ago.

But what I'm looking for is a tutorial.

For example, where would I go online to read the definition(with
images) of what a negative rake is, and whatit does?

Thanks.

Your best bet for that and related questions is _Machinery's Handbook_, any
year. If you don't have a copy, drive over to the Perth Amboy Public
Library. They have one on their reference shelf. There's another one at the
New York Public Library's 96th St. Branch. Maybe your local library can get
it on a loan. (Call number is 621.802 M.)

If you have other questions of that order about machining, you'll find
_Machinery's Handbook_ to be a gold mine.

I actually have "Machinery's Handbook"(27th Edition).

But I was hoping there was a quick convenient reference guide online.

Thanks.

The MSC catalog has a pretty good tutorial on the subject.
I don't know whether the online version has the same detail, but you
can look: www.mscdirect.com, I think.
I wouldn't spend much time on negative rake inserts unless you have a
pretty solid lathe. Remember that you have to force the cutting tool
into the work to get it to cut. If you are "forcing" a positive rake
insert into the work, the included angle of the edge is less than 90
degrees (somewhat acute). A negative rake cutting edge is has a 90
degree angle or more. Less acute, (less "sharp") = more pressure
required to get it to cut = more bending of the the machine before tool
gets pushed into the work = less precision of setting a cut.
Try taking a 1/2 thou cut with even a TPU (7° positive rake) insert.
Then try again with a 12° HSS tool. See which one takes of the metal.
If they both do, then you can think about "N".

I know because I have an Atlas 10" lathe,

So is everyone saying that my AXA 12N with my mini-lathe is not a good
idea for any metals?

I don't speak for everyone, but I was saying that negative rake
doesn't always work WELL on my old lathe. Or maybe I haven't learned
how to use it. Try it, see what happens.
