FOOL-PROOF
ASSEMBLABILITY VERIFICATION:
Gages are
three-dimensional representations of the mating parts, but less
forgiving than the assembly in that they utilize all of the
applicable tolerances to decide the sizes of the gauging
elements. If the part fits the gage, you can rest easy that the
part will fit the assembly. But that is only true if the gages
(and the parts they represent) have been designed, dimensioned
and toleranced correctly.
‘NEW’
GAGING STANDARD:
James
D. Meadows is the chairman and founder of the world’s only
nationally and internationally recognized standard on the
dimensioning and tolerancing of gages and fixtures, ASME
Y14.43-2003 Dimensioning and Tolerancing Principles for Gages
and Fixtures. The extensive rules and principles on how to
properly do this have only been in written form and available to
the public through the ASME Y14.43 standard since this 2003
standard went on sale in 2004. So, unless your gage and fixture
designers have been trained since then per this standard (or
tried to study it on their own), there is no way they could
possibly be designing, dimensioning and tolerancing your gages
100% correctly. James D. Meadows, the world’s leading expert
on gages and fixtures, can teach your employees the rules and
principles needed.
The farther away your products are being manufactured, the less
control you have, and
the more important it is that any parts you ‘BUY’ pass a
functional gage that replicates the worst possible mating
conditions. Only in this
way can you be certain that anything you ‘buy’ will actually
work. Properly designed gages and fixtures can get this control
back for you. If the parts don’t fit the functional gages and
fixtures, don’t buy them! The bottom line is that
incorrectly designed gages could accept non-functional parts or
reject fully functional parts
