GD&T Seminar Wrap-Up |
The initial launch of IIGDT's "Combined
GD&T Course" in Bologna,
Italy was a huge success with multiple companies
attending. While the core training was based on the
ASME Y14.5 Standard there was a critical need to clarify
technical differences between the many standards used
by the various companies. Within one company alone there
were multiple standards used with the perception that
all of them mean the same thing, which is significantly
incorrect.
Some of the standards specified on
engineering drawings were: ANSI/ASME (American), UNI/EN
(Italian), BS (British), DIN (German), MT (Microtechnica)
and ISO (European) only to name a few. It’s critical
that everyone understand that even the definition of a
“Feature of Size” is different between these standards.
Similarly, other geometric symbols such as
Concentricity, Symmetry and Profile of a Line/Surface,
etc. are not defined unilaterally between standards.
Every student was caught off guard
to learn that their long-practiced understanding of the
derived tolerance zone based on plus/minus tolerance was
being interpreted incorrectly. While demonstrating this,
it became clear to all students why disagreements within
their company often extended to the customer and
suppliers.
A common theme of the feedback
at the end of the class was that this training provided
a foundational knowledge to all participates that will
help them with their day-to-day activities and allow
improved efficiencies.
The end result of this
training provided a sound basis for all participants to
understand that optimized application of GD&T will allow
designers to increase feature tolerances and will result
in lower manufacturing and inspection costs as well as
reduced lead time to market. It is the misapplication
and misinterpretation of GD&T that increases
manufacturing and inspection costs and increases lead
time to market.
IIGDT looks forward to future
opportunities to teach in Italy. If companies have an
interest in training at their facility they should
contact IIGDT for a proposal.
