Mike, I downloaded it and it runs, however, it says that I am not
authorized to use it.

I would really much prefer to write my own feeds and speeds
calculator. Both as a perl module (for everyone to write their own
programs) and a website calculator.

I have already started (yesterday or so) a metalworking section on
algebra.com.

I want to do a real speeds and feeds calculator, however.

I have looked up various references and they seem to contradict each
other.

G-Wizard was free while in Beta; maybe it's released now and no longer free.
I think that there was also an email you had to answer (or click on a
contained link) to "authorize" it. There's also ME Consultant Professional,
which I use. The latter can have user entries for materials, feeds, and
speeds but G-Wizard probably does as well. ME Pro is Windows only, though.

It's a complex project if you try to do it right and as you say, different
sources have different data.
