Thanks Chris. It sounds like Mathmatica offers power and flexibility,
but one spends a bit time at the lower end of the learning curve to get
it. I'll have to carve out some time to take a closer look.

I am able to generate the tooth profiles, or rather points on the profile with QCAD by drawing the rack and doing the involute copy/move. This gives me an idea of what's going on. As I learn more, I am able to simplify the process. I have a particular 4:1 gear set I need for my turret encoder on the Shizuoka, which I have enough profile points on. I'll connect the dots with lines, then use dxf2gcode to get the .ngc file. I do have some other projects that need gears. For instance, they don't show up in this photo: http://www.wallacecompany.com/old_lathe/head-1a.jpg but there are a bunch of teeth missing from the small spindle gear and the back gear set on this lathe. I am considering, making new parts from scratch. I think I'll learn enough from the encoder project to be able to get these gears done. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA -- The NEW KODAK i700 Series Scanners deliver under ANY circumstances!

You can see how Mathematica handles your example of the involute of
the circle at the MathWorld site:
http://mathworld.wolfram.com/CircleInvolute.html
where you can download a Mathematica notebook containing code for the
involute, and a free viewer to display the code and the plots.
Wolfram's free viewer, called Mathematica Player, runs on Ubuntu and
other operating systems. There is a prettier version of the involute
packaged as a live demo that runs on Mathematica Player at:
http://demonstrations.wolfram.com/CircleInvolute/
which shows another way to share functions. You need a full version of
Mathematica to create these demos, but anyone can view and manipulate
them for free. In my not so humble opinion, Mathematica is far and
away the best product in the market for working with advanced
mathematics. Some people may squawk at its price (unless you are a
student), or dislike being tied to commercial code, but it will take a
while for the open source community to catch up to Stephen Wolfram and
company.
To share your involute gear function with another Mathematica user you
would email them or post on a web site something like the following
line of text.
d = 1; ParametricPlot[{d (Cos[t] + t Sin[t]), d (-t Cos[t] + Sin[t])},
{t, 0, 2 Pi}]
PS. I use Mathematica for CAD (for R&D, not production work), and
program it to generate g-code for EMC2 directly, or have it write out
text files of coordinates and import these into Catia or Pro/E, when
they run out of steam.

Maybe you should ask someone who has a 28th edition if the metric tables are in that 28th edition? The 1987 version of "Technology of Machine Tools", (Canadian Edition), has a table of metric threads on page 215. 1. The flat at the bottom of the metric thread is twice the flat at the top of the thread. (I am reading this off the rack form of the metric thread). 2. The depth of thread, (D), is 0.6134 times the pitch, (P). The metric thread root is described as thicker, which gives more strength. The 60 degree include angle sounds easy to make a forming tool. Ummm. I suspect you have more Machinery Handbook, local, and email support for American Standard threads. Just before the gear cutting stuff in the 24th Edition, there is a section on cutting racks on milling machines. James Isaac. -- The NEW KODAK i700 Series Scanners deliver under ANY circumstances!

Fully 90 % of the info you will need in the coming years is in the edition you have. I don't know where to tell you to look but the metric gear info is out there somewhere for little or no money. As to the Machinerys hand book my father had ,I think, the 6th edition , my older brother had the 11th About 1939. and my first one was the 13th edition about 1958 they all had mostly the same info though there were additions and deletions as new things came along and old ones became obsolete. My brothers son now is the proud owner of all three editions he is also a machinist. What ever you do keep the old book.

It seems to cover everything I've been trying to hash out the last few days, including the ANSI 20 degree rack form. The gearing section is about four hundred pages, fortunately, about ten or fifteen cover what I need. One problem is my 1971 edition doesn't cover metric gears, so if anyone has any leads to the metric standards, I'd appreciate hearing from you. I suppose I could just buy a current edition.

[Emc-users] almost for how helpful
I recently posted an e-mail to this list and also posted an e-mail to another list about the proprietary CNC software that is discussed there as I have the choice to use either. Here I got several thoughtful answers there I got none. They are nice people on that other list and seem to try to be helpful. It dawned on me that they simply don't know anything about the software they are using or the windows program it's running on. I find myself felling pretty dumb in the face of a lot of superior knowledge here on these Linux groups,thenI think about most of the Windows user I know who haven't got a clue. This list alone makes running EMC2 a worthwhile endevour. It is not everyday in life that you run across a bunch of people who help each other and help others as goes on here. Anyway everyone involved here deserves a little well earned praise. Thanks All, Doug -- The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
