PROJECT TWO: MACHINING (50 POINTS)
Product manufacturing by
material removal or machining processes is another excellent way of exploring
manufacturing processes, such as measurement, layout, facing, drilling, turning,
milling, threading, grooving, slotting, and the associated safety procedures.
To this end, an aluminum clip stand will be fabricated using lathes, mills,
drill presses, sawing machines, grinding machines and hand tools within the
activity time schedule.
The clip stand will be
fabricated using a team approach. Each team will consist of three (3) students.
Each of the three students should be charged with the responsibility of
fabricating one of the following four parts of the clip stand: (1) base, (2)
clamp, and (3) rod and arm. A two-member team should each get a base and arm,
and a clamp and rod respectively. Points are individually earned based on each
student’s performance on their assigned tasks, and on processes where the
group’s combined responsibilities cannot be separated, such as the operation
process chart and assembled product.
1. Introduce students to basic manufacturing processes.
2. Give students an opportunity to fabricate a product and
provide process documentation.
Each student will be given
enough aluminum stock and any associated hardware to fabricate into an approved
product. The student may purchase extra and/or associated material(s) as the
case may be.
Students are required to
review and familiarize relative laboratory tools, safety procedures and
instructor demonstrations before engaging in this project. All written work
must be typed. Each student must produce the following within the activity time
schedule provided (see product activity schedule):
1. Process Planning Documents:
a) Process
charts (8 points)
b) Operation
process charts (7 points)
2. A product approved by instructor to meet the following product
quality attributes:
a)
All specified product dimensions to be within +/- .005” (15 points)
b)
Overall finish
(burrs, dents, tool marks, scratches, dirt, warps, roughness etc.) (10)
c)
Assembled product
functionality (functional, completeness, durability, sits square when
assembled, strong assembly etc.) 10
SUGGESTED PROCEDURES
1. Begin
by studying the drawings provided by instructor
2. Do your
process planning (must be typed)
3. Request for your material
4. Process material
5. Submit for grading
