Good luck!
Worth reading about the spec before investing a lot of time or cost with cutters.

Ok well, it's a good grade to cut, not so sticky. However, your cutter is quite long and being straight flutes not ideally suited to aluminium. The stick out will have a large effect on feeds and the straight flutes won't clear chips very well. So I'll say it again because cannot stress enough how important it is to clear the chips away, lots of Air and occassional spray of WD40 will be needed.
Given these new details, I would start with halfing those settings I gave before and work up changing one setting at a time to see the effect. 1st I would play with RPM, then Feed then DOC.-use common sense, if you lack it, there is no software to help that.

Thanks guys for the great help, I have a few items to come before I can design the plates, but I will try some different settings on some scrap.
To be honest I have been a bit afraid to try it, but now at least I have some faint idea.

Taking this conversation on a step but still speeds and feeds related....
Does anyone have an opinion on a product called "GWizard"? It's a paid for program but might be a good starting point for us newbies. There is a 30day trial and on the surface seems informative, as I say it may be just a starting point for newbies?
