- [Instructor] Here are a few tips to help you communicate
with a new manufacturer.
First, it's important to find out whether or not
they use Geometric Dimensioning and Tolerancing practices.
Manufacturers that use Plus and Minus Tolerancing
may be able to fabricate your parts,
but extra work will be required to ensure
the quality and consistency of those parts.
Second, it's important to get a list
of the manufacturing tolerances
available from your machine shop.
Third, it's important to know how your part geometry
will be verified after manufacturing
and how precise that verification process is.
Finally, if you yourself are new
to Geometric Dimensioning and Tolerancing,
it's possible that you have not completely defined
the geometric dimensions and tolerances of your part.
Whenever possible, confirm with your shop
that they understand your tolerances
and your design intent.
It is helpful if you can review the verification process
with a machine shop as well.
If anything is unclear, or ambiguous about the CAD geometry
or the verification steps,
clarify these items with a machine shop before proceeding.
If you have successfully implemented
the Geometric Dimensioning and Tolerancing standards,
your dimension part contains all the information
required for that part
to be manufactured to your specification.
The manufacturer should be able to fully understand
the manufacturing constraints and design intent
without any further annotation or notes.
