A few years ago, I was helping a fellow near Cleveland with milling a PCB. He had a Tormach Personal CNC and was able to convert/load the Eagle files. I do not recall the program he was using, as I had no plans for CNC at that time.
You might check with Tormach or post to its forum.
Its fine john, it was the poly's that made things a bit too complicated.
