Re: [CAD_CAM_EDM_DRO] Are there CNC-only jobs, or is it only for duplicates?

Outside of 3D surfacing, there's not much that can't be done manually.
Trouble is, most of the folks that know how to do it are retired or
close to it.
CNC can do a wonderful job of covering up for a lack of experience in
setups, lack of tooling on hand for complicated setups, and can vastly
reduce the number of setups.
If one is careful with the approach taken, and the coding (CAM sure
helps here...), the potential for mistakes can be reduced. If a mistake
IS made, it can be corrected and another part made in much less time
than would have taken manually.
If that on-off part ever breaks or wears out, another exact duplicate
can be made quickly.

And the Gee-whiz factor cannot be overlooked. I ran a Wells Index for
several years, and have seen most of the state of the art machinery. But
when I got my MaxNC and ran the supplied Wheel.T test program, I could
not suppress my grin at this little thing sitting on my bench making
chips under PC control!
