Gee.... with a CAD/CAM system you could dimension the part as
drawn & check it for errors .... just for starters. Fix any typos BEFORE
making all that $$ scrap.
Then there are all those fancy G & M codes to type .. and all those
numbers ..
and all those other codes .... almost free from a decent post ... then
DAYS of
Zen at the control wondering what went wrong ..
And you might even have CAD data to start with !!
Nobody ever sold you any clues, eh?
