The lab is intended to accomplish four goals:
-
To
introduce the basic machine tool, the Mill, used in manufacturing
shops and their related terminologies to the students.
-
To
learn the importance of tolerance and dimensioning in
manufacturing.
-
To
practice the team work concept and basic design elements
through a hands-on practice that will produce a product.
-
To
practice the safety and other rules related to working in a
manufacturing shop floor.
-
To
provide an experiment through which students recognize the
level of skills and time needed for the manual jobs.

Manufacture: A rectangular block.
Tools & Equipment: Smithy 3 in 1 Lathe-Mill-Drill Press, vise, Vernier caliper, micrometer, blue dye, scribe,
protractor.
Instructions: Please make sure that you have read the
lab work rules and regulations before you start working in the lab. It
is important that you follow these instructions in order to obtain the
maximum points allowed for this assignment.
Safety is once again stressed. Pay
particular attention to operational instruction of the Smithy
machines. Note: They are different with many overlapping
similarities.
Mill the piece to have a 0.25" (A, B, C, D, and F) raised
pocketed border as illustrated in the picture below,
with the exception of
‘E’. The dimension of ‘E’
is 0.1”.
The diagram represents only the top
portion of the block you are making.
Design the interior space using each of the three elements
(listed below) at least once.
Submit dimensioned sketch for approval before working on
the Smithy.
Submit your
project before the due date. The produced part should be submitted
separately in a plastic bag with the group name and members listed.
Reserve a
presentation time, present and demonstrate you project along with
the lab field research assignment.
Your grade for this assignment is a
combination of some general evaluation guidelines and some specific ones
related to this assignment.
General Guidelines
-
How well the
team worked together
-
Whether the
team members observed the safety rules and other rules as explained
in the Lab Work document.
-
Whether the
team progress was on a uniform basis or most of the work was done at
the end.
-
Whether the
team followed the rules set for the lab work or not.
-
The quality
of the report, presentation, and demonstration.
HINTS
Remember the assumptions regarding the Smithy with
which this task was assigned.
Be mindful of the uneven sides when placing the part
in the vise. Use less force (remove less material per pass) to prevent
the part shifting.
