The ideal speed will depend on your spindle speed and also machine rigidity so is difficult to say. I cut acetal at 18k rpm and 6500 mm/min...

For 2D you can use Draftsight, 3D and CAM try Fusion 360. both are free and both can (I believe) be run on a Mac.

Wow that fusion is a little out of my price range (for now)
