Lab Report

the
students will develop a detailed technical drawing of a plastic toy block,
starting with making hand
sketches, measuring geometric features using common metrological tools, and creating a CAD drawing.
Objective
s
:

To familiarize yourself with the use of a vernier caliper and micrometer.

To refresh and apply your technical drawi
ng skills.

To consider the manufacturing processes involved in the creation of a simple toy.
Experimental
Procedure:
Step 1:
Calipers and Micrometers

Read the attached material regarding the use of the
v
ernier caliper and the micrometer.

Sketch the
given piece on a paper sheet.

Measure
the dimensions of the given piece
with both
v
ernier calipers and
/or
micrometers
.

Record your measurements on
the sketch
. Make sure to measure internal geometries and thicknesses. Your
drawing should fully describe the
entire part.
Step
2
:
Creating a CAD Drawing

Convert your hand
sketch into a scale CAD drawing
.
Step
3
:
Questions
1.
Speculate as to what manufacturing techniques are used to produce the
Lego
block.
Make reasonable guesses
and explain your reasoning.
2.
Notice that the block has internal ribs. (Did you include them in your drawing?) What is the purpose of these
ribs? Why are they located where they are?
3.
Estimate the volume of material used to manufacture the Duplo block. How did you come to
your
estimate?
4.
Is the part perfectly symmetrical? Are the thicknesses consistent across surfaces?
5.
The interior of the part has markings. How were these markings created?
6.
Comment on which block features and dimensions may be critical from a manufacturing po
int of view
(hypothesize on how the blocks are made and what would make a block easy to make).
7.
Comment about what block features and dimensions are critical from the functional point of view (e.g.,
interaction when used with other blocks)
