Drawing a circular object with radial objects couldn't be easier in Acad, You would then need to run it through a CAM program such as Lazycam under Mach prepares the drawing for CNC machining, tool offsets etc, and then it runs through a post processor that converts it to G/M code etc.
If you want tutorial hard copy, search in Abe Books clearing house, I picked up a box full of manuals 10c on the $.
