I need to make an "jet airplane intake" so I have made a 3D rendering in AutoCAD 2013 and plan to cut a mold out of light weight material.

I have no idea how to cut this. To say I'm a NEWBIE is an overstatement of my qualifications. I haven't even received my CNC yet! Hey, I have ordered & paid for it.

I have ordered a 4 Axis router that comes with Artcam & MACH3 and I intend to buy VCarve Pro. Will any those software's work or do I need to look something else?
