COURSE SYLLABUS

1. TITLE OF COURSE: Mechanical Design I
PREFIX/NUMBER: ENT 233 CREDIT HOURS: 3.0
2. PREREQUISITE: ENT 133 and ENT 132
3. RESOURCES NEEDED:

TEXT:

Jig and Fixture Design by Edward G. Hoffman, 4th edition Delmar Publishers
Machinery’s Handbook

SUPPLIES:

Notebook, pencil, 3 ½” HD floppy diskettes, calculator
4. COURSE DESCRIPTION: The industrial design process from layout to production drawings, jib and fixture design, standard part selection from handbooks and catalogs, specification writing, and part ordering will be covered.
5. COURSE GOAL: The student will demonstrate the ability to design and document various types of machining jigs and fixtures used in modern manufacturing.
6. COURSE OBJECTIVES:
  A. The student will describe the purpose of tool design in manufacturing.
  B. The student will be able to list the types and functions of jigs and fixtures used in modern manufacturing.
  C. The student will be able to describe part supporting and locating principles applied to jigs and fixtures used in machining processes.
  D. The student will describe part clamping and work holding principles used in jigs and fixtures used in machining processes.
  E. The student will be able to describe basic jig and fixture construction principles.
  F. The student will be able to describe the principles used in design economics and how they affect manufacturing decisions.
  G. The student will perform predesign analysis for a part in order to determine the tool design concept based upon human elements, previous machining operations, and tooling alternatives.
  H. The student will be able to describe the factors involved in producing tool drawings including simplification techniques, dimensioning techniques, GD&T considerations, and the use of CAD in tool design.
  I. The student will produce a template jig design for a simple machined part.
  J. The student will describe the factors involved in producing a vise-held and plate fixture.
  K. The student will produce a plate jig design for a simple machined part.
  L. The student will be able to describe the factors involved in producing an angle-plate jig and fixture.
  M. The student will be able to describe the factors involved in producing channel and box jigs.
  N. The student will produce a fixture design based on power workholding principles.
  O. The student will be able to describe modular fixturing systems and their applications.
7. EVALUATION PROCEDURES:
The student receives a letter grade based upon the successful completion of the tests and lab assignments assigned by the instructor.  At the completion of this course the student should be familiar with the methods used to produce manufacturing tooling to meet specific design criteria. This will be evidenced by the completion of 76% of the assigned tasks in the course.
Each quiz and lab assignment is worth 100 points.

GRADING SCALE

Raw Score Range

 Letter Grade Grade Point Earned
100 to 94 A 12
93 to 87 B 9
86 to 76 C 6
75 to 70 D 3
69 to 0 F 0
The total number of points earned by each student divided by the points possible will give a percentage that relates directly to this grade chart for the final grade.
A final exam will be given which reviews all of the concepts covered in the course.
Special Remarks:
1. Attendance:  College policy states that students may be dropped from enrollment when absent 20% of the scheduled class meetings.  If enrolled from the beginning of the term, 15 hours will usually constitute 20% of a four-credit semester course which meets five hours per week.  Reinstatement procedures are described in the PCC catalog.
2. Tardy Policy:  A student who is late three times (enters classroom after the instructor has taken roll) will be charged with one full absence unless the student can provide valid reasons for one or more of these tardies.
3. Assignments/Missed Exams:  It is the student's responsibility, whether present or absent, to obtain all material presented and to complete all course assignments.  If prior arrangements are made or extenuating circumstances exist, makeup of tests may be allowed.  Late homework papers will not be accepted unless those same extenuating circumstances exist.  Makeup of quizzes is to be at the instructor's discretion.
8. COURSE OUTLINE
9. METHODS OF INSTRUCTION:
To be successful in this course, students are expected to participate in discussions, readings, in-class writing, and peer review activities. The instructor may assign point values to such activities.
10. ACADEMIC INTEGRITY:
The very nature of higher education requires that students adhere to accepted standards of academic integrity. Therefore, Pueblo Community College has adopted a policy of academic conduct as described in the Student Handbook. Violation of academic integrity may be defined to include the following: cheating, plagiarism, falsification and fabrication, abuse of academic materials, complicity in academic dishonesty, and personal misrepresentation. It is the student’s responsibility to be aware of the behaviors that constitute academic dishonesty. Sanctions for violating the standards of academic integrity may include warning, probation, suspension, and/or failure of the course or assignment at the discretion of the instructor.
11. ADA NOTICE:
Students who have a documented disability may be eligible to receive accommodations for this class. Please contact the Disability Resources Center at 549-3446 for further information.
