Boris,
Sounds like you're training a CNC OPERATOR, not a machinist.
"when the green button is pressed, a finished part pops out 5 mins later"
My feeling is a machinist needs to at least be able
to grind a tool, to chase a thread,
or bore a hole to size, to figure his own procedure,
and tools, to rough, and finish the parts you hand him.

I think you missed the bit where I said here's the tools, the fixture, now load it into the machine before getting a finished part.
But as a trainee CNC setter, the first job they all do for me after 3 months operating is this:
"There are 3 cutters machining the part, they are defined in terms of length and radius, if you make the radius smaller, the part gets smaller.
This part , however is 0.004" undersize, change tool 3 radius to bring it back on size"
After machining a part, they are then handed the micrometer and asked to measure the part.
That is where every trainee/apprentice I've taught starts (and some end there too
)
When they've got the hang of changing the offsets, then its onto changing the tools, indicating vices, locating datums, reading the setup sheets komplete wiff spellink ewwors
Once they've got the hang of all that, do I start on programming, then tool selection, feeds, speeds, materials etc.
As for thread chasing...change the thread mill offset and re-run the cycle until the thread is the right size
I'm not training people to be a manual machinist in the traditions of us old timers who used to twirl handles all day and make it look easy
I'm training people in most aspects of 3 and 4 axis CNC work because thats where the money is
Plus who really wants to be stuck in front of a b/p clone being blasted by chips anymore?
