Geometric Dimensioning
and Tolerancing
WMG MSc Module
GD&T is a symbolic language by which the relationships
of parts and assemblies are represented while considering
their functional requirements. This module creates the
foundations upon which it is possible to determine the
correct engineering specification with the appropriate
application of GD&T roles and principles.
The module is valuable to several departments in a
manufacturing enterprise including R&D, product
design, manufacturing engineering, quality and
process improvement, and manufacturing and supplier
management.
What will you study?
What will you gain?
The module will be delivered through lectures covering
theory and practical examples, as well as group exercises.
On completion, as a successful participant you should
expect to be able to:
Topics will include:
cc Understand relevant dimensioning and tolerancing
standards with focus on ISO SPG standards
cc An introduction to manufacturing methods and
technologies, and surface properties
cc An introduction to design drawing, dimensioning, and
tolerancing standards
cc Datum systems
cc Geometrical Dimensioning and Tolerancing including:
background, standards, feature control frames, geometric
characteristics, symbols for boundaries and material
conditions, GD&T concepts in details, review of GD&T on
sample drawings
cc Understand the main and critical GD&T controls, rules,
and modifying symbols
cc Understand datum reference frames
cc Be familiar with the impact of dimensional variation and
tolerance stack-up
cc Interpret, and base engineering decisions on, part and
assembly specifications
cc Conduct tolerance stack-up analysis on simple models
cc Measurement requirement understanding for parts with
GD&T information
cc Tolerancing of flexible parts
cc Tolerance chain
cc Practical measurement of parts with GD&T information
Duration: 5 days
Assessment: Post module assignment
