NC Pros and Cons

Looking to get into PC-Dmis NC. We currently use Renishaw touch probes to locate parts. Never used them for actual measurements.

Some info:

I'm a CMM guy, not a machinist, is that a problem for NC?
The machinists we do have tend to crash the machines a lot.
Trying to reduce or eliminate human qc steps.
Make small and large parts for oil and gas industry.
Tightest tolerance would be 0.0005in.
Mostly steel, some brass and aluminium.
Machines are Haas mills and Mori multi turning centers. Mori Lathes, 1 Toshiba large boring mill.
Don't know if I need 3, 4 or 5 axis NC Options.
What if I what a singe probe and a star probe?

I got some info from our sales person but I'm still looking for other info. Seems to be cheaper than buying another CMM. We are buying new CNC mulit turning centers like ever other month now. Most of which have tooling carousels with plenty of free space. One purchase came with a renishaw probe that uses radio frequencies. A mori person was here setting it up to locate the part. I asked her about actual measurements and reporting but she didn't know about that side of it.

Any advice or input would be appreciated.
