Course Description

Continues to explore the use of geometric dimensioning and tolerancing (GDT) as specified by the American Society of Mechanical Engineers in specification ASME Y14.5-2009. Covers the symbols, concepts, and basic use of these techniques for dimensioning and tolerancing used in standard industry practice. This course is also offered as APR 116M; a student who enrolls in this course a second time under either designator will be subject to the course repeat policy. Audit available.

Addendum to Course Description

GD&T II is presents a additional features of GD&T that will be of interest to machinists, metrologists, and engineers.

TEXT:

A Practical Guide to Geometric Tolerancing per ASME Y14.5-2009 by Scott Neumann and Al Neumann.  ISBN 087263865-0    

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Apply both rectangular and feature based datum reference frames in measurements.
  • Competently measure a profile tolerance.
  • Competently measure a coaxial tolerance.
  • Understand and explain shape tolerances.

Aspirational Goals

This class continues the presentation of GD&T concepts that will be of use to advanced machinists, metrologists, and engineers.

Course Activities and Design

Presented by means of audio visual presentations, demonstrations, and research activities. The course activities and design emphasize the development of skills and knowledge outcomes prescribed by established industry standards. The identified outcomes will be achieved by means of individual and team activities.  

Outcome Assessment Strategies

The final grade will be based on the average of a mid-term and a final exam.  The exams present problems related to tolerances similar to those presented in the textbook exercises.
