Course description:

Jigs and fixtures for production machining processes are covered. Specific subjects include methods of gaging work pieces, ease and simplicity of operation, assembly methods, capital evaluation, and techniques for locating and holding work pieces, time studies, tool steels, bending allowances, and reverse engineering techniques. The course is design project oriented. Projects include calculations of tooling forces and costs as well as complete production drawings of the tool design.



Course texts:


1- Fundamentals of tool design, 5th Edition, SME (by David Spitler (Contributor, Editor), Society of Manufacturing Engineers (Contributor, Corporate Author), Jeff Lantrip (Editor, Translator), John G. Nee (Editor, Translator), David A. Smith (Editor, Translator)) ISBN-10: 087263650X

About the book

This revised edition contains new material from leading industry experts on topics such as rapid prototyping, design of pressworking tools, bending, forming and drawing, forging dies, inspection and gaging, CAD applications, and more. It is more searchable and "user-friendly" than the previous version. As before, the book outlines all the factors that impact tool success, showing how and why tools work in relation to the manufacturing processes for which they are being designed. Each chapter details the "nuts & bolts" of tool design-- such as material science, tool layout, cost analysis, calculating economical lot sizes, safety, and more.

2- Jig and fixture design, 5th Edition, Hoffman, ISBN: 9781401811075

About the book

By emphasizing similarities among types and styles, Jig and Fixture Design, 5E speeds readers to a complete understanding of the why's and how's of designing and building a variety of different workholders for manufacturing. From simple template and plate-type jigs to complex channel and box-type tooling, this newly revised edition features more than 500 illustrations of tools and applications to spur readers to success. All-new sections on assembly tools, handling tools, and catalog reading enable readers to develop important skills. Specific examples of various jigs and commercially available fixtures also appear to guide readers in developing their understanding of how design principles, as well as the latest design and manufacturing technologies, are being applied in the construction of jigs and fixtures today. As in past editions, heavy emphasis is placed on the economics of jigs and fixtures, including methods and formulas for use in estimating workholder costs. A solid background in industrial processes, as well as machine shop technology, is assumed.

Your grade in this course will be determined from your performance on:

o   In-class participation/ Homework Assignments

o   Projects (including presentations),

o   Quizzes and tests.


Attendance is mandatory and points will be taken off final grade in case of illegitimate absence. There are many in-class projects for which the students should attend the class.


Homework Assignments will be given periodically.


Projects will be assigned after certain modules are covered. Projects are related to locating and clamping, jigs, fixtures, gages and dies.


Tests are either in the form of multiple choices or problem solving and are given at the beginning of the classes. These tests cover the course materials which were taught in the previous session (or sessions).



Grading policy:


  • In-class participation & HW assignments       10%
  • Quizzes/ Tests:                                                35%
  • Projects:                                                          55%

Total:                                                               100%


[90 - 100% = A,   80 - 89% = B   70 - 79% = C   60 - 69% = D   Below 60% = F]
