Newbie Question - speeds and feeds

There are those of us that are new to machining that would like a
little help in calculating speeds and feeds for different materials
and thicknesses. I have Machinings Handbook and I know it includes
ways to calculate these things but you have to wade through a lot to
get to the parts specific to your needs.

My particular calculations regard milling. My understanding is that
you need about 8 inputs: tool cutting diameter,number of flutes or
inserts, tool cutting depth, tool cutting material(HSS, carbide,
etc),material to be cut (al 6051,al 7075 etc.),finishing or rough
cut,horsepower of milling machine. Finally if rpm is given -
calculate feed rate and depth of cut. Or calculate all three.

When looked at in total these are not trivial calculations. I wish
there was a program out there that could do these calculations for
me. It might even be able to be done in spreadsheet form and it sure
seems like the kind of problem computers were made for. Anyone out
there know of a cheap program that does these calculations? It would
be nice to have it integrated with a cam program but I fear that
adding it would be just the excuse a company would need to jack up
the price. It might be more convienient to just have a stand alone
product. Any help would be appreciated.
