Thank you. That is just the overview I needed to understand the function of the software.
Just to let you know, TurboCADCAM is still on thier website at:

I understand now why some are using TurboCADCAM with Mach 3. I think that I will experiment first with the free software. I am fairly sure I will want to be able to design in 3D eventually. Given the TurboCADCAM educational discount and my familiarity with drafting in TruboCAD, it may be a good option when I get to it. Obviously, I need to build the machine first!!! I just like to have all my steps planned before I begin a job. OCD, gotta love it!
