For the assignment of the 8th week: Computer-Controlled Machining, it will be divided into 4 differentiated parts: Design, Fabrication, Assembly and Files.
For the assignment of the 8th week: Computer-Controlled Machining, it will be divided into 5 differentiated parts: Design, Fabrication, Assembly, download files and group assignment.
The goal of this week it is create something BIG.

<h2>Desing</h2>
My idea for this week is to create a shelf that can be scaled to have different levels, ideal to take advantage of some free space you have at home.
<a title="My design"><img class="image center" src="images/week8/designinventor.jpg"></a>
My idea for this week is to create a small showcase, this can be scalable to be composed of different parts.
This design can be parametric without major problems, however, since it is a piece of furniture that I will use in my home, I have the exact measurements and I digit them directly without designing in a parametric way.<br>
It will be divided into three main parts:<br>
<div class="row">
<ol>
<li>Base</li>
Here will be the legs of the shelf.
<li>The body</li>
This area can be increased depending on the space needed
<li>The final part</li>
It will have some small ornaments where you can hold in case you want to move without disarming it
</ol>
</div>
The design must have a particularity in the corners to obtain the desired result. The tool chosen will be a circular endmill, when we want to make internal 90º angles we will not have the desired thing since we do not get what we want, then an picture explaining the detail.
<a title="Corner"><img class="image center" src="images/week8/corner.jpg"></a>
For this reason and knowing that the diameter of the tool is 3/16 "that would be about 4.8mm, the following design is made in the corners:
<a title="New corners"><img class="image center" src="images/week8/newcorners.jpg"></a>
A circle is drawn at a distance r / 2 from the corner, the radius of the tool being used, so we make sure that the desired corner can exist.
It is about not having a greater distance to avoid having very deformed shapes in our design.
<br><h3>Base</h3>
The base consists of a table as a base and the front and side legs, as shown in the picture
<a title="Base parts"><img class="image center" src="images/week8/base.jpg"></a>
<br><h3>Central</h3>
For the central part, which is the modular zone, it is composed of 3 parts, as you can see in the picture
For the central part, which is the modular zone, it is composed of 3 parts: left side, right side and back side, as you can see in the picture
<a title="Central parts"><img class="image center" src="images/week8/central.jpg"></a>
<br><h3>Final</h3>
For the final zone, two pieces of the central zone and additional pieces are used, as shown in the figure

Below you can see a small animation of how the final assembly of our design will be.<br>

<h2>Fabrication</h2>
In the lab, we use the CNC Multicam 3000, you can read more about the machine<a href="https://www.multicam.com/3000-series-cnc-router/">here.</a>
The first step is to place the 2.5m x 1.3m plywood plate by screwing it into the base and placing some nails to hold it.
