Conclusion

This SKE assignment has been a challenge and an opportunity to acquire more CAD/CAM knowledge. The final product meets my specification  and is a good outcome of the design brief analysis. However, there are a few things I could have done differently the second time round. These are:

1. Make the whole casing much bigger to comfortably accommodate all components with enough space left
    to manouver in case of any repairs/adjustments.

2. Have a better way to join the speaker, the casing and the speaker cover together.

3. Make the casing walls thicker to enable bigger surface contact between the two halves for a stronger joint.

 This would have made the use of a "fin" unnnecessary.

Final outcome

.

My initial drawing had problems with
the sides for the block size not at right
angles to conform with the machine axis.
I had to make changes and to make my
work a maximum of 50mm to fit the
recommended block thickness. The
speaker casing was finally completed
on the CNC machine after several changes and minor problems

Finalising the design

The final design outcome has been good

 and the work remaining was to turn it to

an STL file for machining.

Assembly and fitting it all together

The parts fitted well with all parts

accommodated. I hoewever had to

use the 9 volt battrery because my

design is small and had to be portable

for the musuc fan who is always on

 "the go"

ProEngineer Skills and challenges

Several times I got stuck and sought help.

I learned and acquired new skills and

techniques as I received the assistance

to develop my design. I specifically got
to understand much better the skill of
navigating forward and backwords to
correct errors and effect modifications.

Further Development using ProE

I initially used the sweep technique and

the mirror tool to create a solid with

slanting front and receeding sides as

per my hand sketches. The result was

impressive but after shelling the solid

there was little or very thin web left to

effectively join the two halves with

adequate contact surface area for a

strong joint.

Continuing research and refining the sketches.

As I continued with my analysis of the brief,

my focus narrowed more and more towards

a simple small amplifier/speaker and thus I

continued to refine my design. After making
 my decision about the shape and approximate
size, I then decided to continue the sketching
using CAD, specifically ProEngineer.

WELCOME TO MY BLOG

This is my mood board that I

compiled to help me focus on

my chosen theme of high speed

 trains. The curved sides and

 aerodynamic shape of the fast

 trains gave me my first design

 ideas of having a speaker that
 has curved surfaces and
receeding sides to look stylish.
