6 plants, so far. Where did you get 1 or 2 from?

Try reading for content. "What's the info?" That means you gave no initial
info, and I'm asking for more.

"That he install equipment there, and can only tell you things he's seen at
one or two Ford or Chrysler plants?" The question mark at the end signifies
that I'm asking a question, not making a statement. It's a possible
scenario to your mysterious situation.

Got it now?


The purchaser of the CNC equipment can specify, within a certain range,
how
tightly they want to limit tolerances. That's a mechanical adjustment.

No, it's a designed-in ability of the CNC machine to be able to hold, and
repeat said tolerance. It's a mechanical adjustment to setup the machine
initially to perfom correctly, and to re-adjust or fix it when it wears
enough to lose its accuracy.

After engine parts are made, each manufacturer decides what's considered a
rejected part, and what gets used. This is a management decision. The
difference between what Toyota will accept and what Ford, Chrysler and GM
will accept does not fall into the category of "negligible".

If you think this is obtuse, let me know in your next post.


Still fairly obtuse. What is said CNC equipment being used to manufacture?
Pistons at Toyota and alternator brackets at Ford? You do realize that
there would be a *huge* difference in the pass/fail parameters for different
types of parts, right? And lets not forget about the fact that the *design*
of the overall gizmo (engine, brake caliper, etc...) determines what
tolerances need to be kept, and those acceptable tolerance ranges aren't an
indication of quality in and of themselves. Also, management does not
decide what is acceptable to be used in a design. Engineering gives them
the ranges to use, and management enforces that. If the range is too tight
to be cost effectively manufactured, a re-design is indicated.

Besides, you do realize that Ford and Toyota don't make their own pistons,
right? They each have hundreds of suppliers, each making some unique part
they specialize in. For example, the Wiseco company could, and probably
does, make pistons for both Ford and Toyota USA.

Is your ass not getting tired of talking? Have another drink, Kanter.

(note to Kanter... you didn't say pistons... I'm using them as an example...
