Course Description

Covers the use of geometric dimensioning and tolerancing as specified by the American Society of Mechanical Engineers in specification ASME Y14.5-2009. Introduces the symbols, concepts and basic use of these techniques for dimensioning and tolerancing used in industry today. Audit available.

Addendum to Course Description

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

The student, upon successful completion of the course, shall be able to demonstrate an entry-level knowledge of dimensions and tolerances as expressed on an industry standard print relating to the following topics:

  • Minimum and maximum material conditions

  • Position tolerances with applied material conditions.

  • Datum reference frames

  • Profile tolerances.

  • Shape tolerances.

Course Activities and Design

MCH 115 will be 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.
