Course Information and Outline .
Course Title Workshop Theory and Practice
Course Code ME 302
Description The course deals with the basic principles of machine shop
practices. It includes workshop safety and organization; simple
workshop measuring instruments, hand tools, fitting bench work,
bench drill and bench grinder; sheet metal working; principles of
welding processes; welding metallurgy; joining processes; testing
and inspection of welds.
Course Objective At the end of the course, the students are expected to
1. Identify common shop hand tools, drill press, lathe
machine, and welding machine.
2. Read Vernier Calipers and other measuring instruments
3. Design and fabricate project using various machines stated
above.
4. Work harmoniously with team members playing different
roles
Requirements Project Fabrication. Individual projects will be fabricated by the
students for them to apply the procedures and operations
discussed during lectures. The project will allow students to develop
and acquire skills and proper work ethics in the work shop.
Group or Individual Exercise. Group or individual exercises will
be given after every lecture for the students to apply the basic
theories discussed. The student will be encouraged to work in
teams in different activities as a preparation for the project
fabrication.
Preliminary and Final Exam. The regular end-of-term exam to
evaluate student on how much they have learned in course.
Class Standing. Class standing includes group exercises to be
submitted during every meeting and assignments.

- 2. Mechanical Engineering Department Schedule Wk Topics/Activities 1 Orientation, discuss the rules and guidelines for the machine shop laboratory Safety orientation The class will be divided into groups of 4-5 members per group. Read hand-outs 001: Rules and Guidelines for the Machine Shop Laboratory Assignment #1: Submit 3 posters in a cardboard size 17” x 11” showing or illustrating Safety in the Machine shop terms of (1) Personal grooming (2) Safe work practices (3) General Housekeeping The poster must be manually drawn and painted with any painting material and submitted with plastic cover. Prepare to discuss your poster next meeting. 2 Topic: Bench and Hand Tools and Steel Rules Read hand-outs #002: Bench and Hand Tools Exercise #1: (Individual) (1) Part 1: Fabricate a 22mm x 22mm x 60mm part fully polished with 45 degree chamfer in each side. Use mild steel. (2) Part 2: Fabricate a 25mm x 50mm x 10mm part fully polished with 45 degree chamfer in each side. This part must also have one 45 degree (5mm on each side) cut on one edge. Use mild steel. Read hand-outs #003: Drilling Machines 3 Submission of Exercise #1 Exercise #1 will be evaluated in terms of the following criteria: Accuracy: 50% Surface Finish: 40% Packaging: 10% Read hand-outs #004: Hand Taps Read hand-outs #005: Metals and their Properties 4 Topic: Hand Taps and Drill Press 2011
