I am purchasing a PM727 and PM1022 mill and lathe. I was considering in the future making them where they could be used for both CNC and manual machining if that was possible. What would be the cost of making a basic, three axis CNC milling machine- roughly? I have a computer for it already, and had planned on using servo motors if I go this route.
Also, is there a way for a CNC machine to check to see if the cutting bit is still viable- so that if it breaks it simply stops trying to make the piece? Would a fourth axis in the form of a rotary table mounted so that the work piece was horizontal work in lieu of having a CNC lathe?
Sorry if any of this seems kind of dumb, I really don't know all that much about CNC- but it does look interesting.
