Where are you getting your code from that you need to edit it? If you are using a CAM programme then you may be better editing the Post Processor so that it puts out the correct code for your particular machine.
For the spindle speed and feed in Alu it will depend on quite a few factors, really you want to be able to slow down or speed up your spindle but I am not sure if this is possible. The factors that will determine the feed and spindle speed are cutter size, cutter material (HSS, Carbide etc) and amout of flutes.
Have a look at Machinists Mate, its a nice wee programme that will give you a good general idea of what feeds/speeds you will need for different conditions and after the demo has run out its cheap, that is if you find it usefull.
