Who Should Attend?
This is the course that all
practitioners of Geometric Dimensioning and Tolerancing who work in
internationally-owned companies have been looking for.
This course is designed
for professionals whose work requires them to know, apply or interpret both
international geometrical tolerances created per ISO standards and geometric
tolerances created per ASME Y14.5M-1994.
If you have to deal with both
national and international product drawings or
3D models and their accompanying geometric tolerances, this course is for you.
If your company is comparing ISO
and ASME tolerancing systems, their symbols,
rules and practices and trying to decide which to go with as company policy,
this course is for you.
Whether you are involved in design, manufacturing,
inspection, quality, product engineering or process engineering or are a manager
of technical people in these areas and have to work with both national and
international dimensioning and tolerancing practices, this is the course you
need.

Course
Description:
This course teaches the
most important concepts of ISO and ASME dimensioning and tolerancing
practices concentrating on the similarities and differences between the
standards. Included in this course is a comparison of symbols, terms,
definitions and practices (both current and past) of ISO and ASME
geometric dimensioning and tolerancing. This course, and its
accompanying books and handouts, draw material from 17 of the most
current ISO and ASME standards, technical papers and textbooks that
relate to dimensioning and tolerancing.
