Re: [CAD_CAM_EDM_DRO] Router Cutting Aluminum

Joe -
Your question really has several parts, but one part is

"is it workable to use a small diameter cutting tool and a high spindle
speed"?

Yes - My Roland CNC uses such a system, and so does a Dremel tool or a
flex shaft tool like a Foredom.

Indeed, one advantage of such a system is that you could machine very hard
materials by mounting a grinding point.

As for the rest of it, I'll leave to others with greater wisdom.
