Ever the optimist, when I bought CAD/CAM I cheerfully imagined that using a solid model which had been given to me I could just point the CAM at it and press a button ;-)
12 months after that I finally reached the point where I was rarely stuck with anything 2D, 2.5D or 3-Axis 3D

When you buy CAD/CAM it's worth looking at what learning resources and user group support is available, good tutorials and a good support forum are invaluable resources for a new user,
