Re: [CAD_CAM_EDM_DRO] Re: Names

I think the point Fred is trying to make is that CNC is not always the best
choice. Considering the business he is in (selling CAD/CAM software) I think
it is pretty honorable that he would point out that using the cranks can
sometimes be a much faster may to get specific jobs done. OTOH, as you point
out Jon there are jobs that can't be done as efficiently or at all with
manual methods.
