Week #2 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What were you inspired by?

This week the task idea was to know about fusion 360 program and how it works , and discovering different examples to get used to it .

I got inspired from the tutorials , as I learned the main aim of the program and how to use it and knew more about Its interface .

Tool Chain

Which software/machines/materials did you use this week? Why?

software used : fusion 360 program , I started to sketch different drawings to practice on it ( the nuke symbol and the catapult ) , this was through watching the tutorials to know how to start sketching .

Design Process

Explain the design process of your assignment. How did you use the tool/software to design and/or simulate your assignment?

The nuke symbol

-First thing I started a new sketch , and picked the plane to work on

-Then I started to draw the outer triangle with poly line tool

-After this I drew the two circles at the center of intersection of the triangle medians

-Then I started to draw the poly lines from the center with Its specified angles

-The last thing I used the trim tool to trim the unwanted parts of the circles .

-Then I extruded the shape 3mm with the thickness of the wood to be ready for laser cutting .

Nuke symbol 1 .mp4

Using circular patterns :

-The same steps of the previous drawing till the drawing of the two circles

-After this I drew only two polylines from the center

-Trimmed the other parts

-Then From the create panel -> insert circular panel

-Selected the shape and the center

-The other two parts are drawn

-The last step was to extrude the shape

Constraints :

-After drawing the nuke symbol it's still not fully defined

-I started to make it defined through different constraints :

Horizontal constraint for the base
making from the center construction line (colinear with the lines from the center )
Adding angles and dimensions

Catapult Drawing

Ball thrower and DMS

First I started to draw the left part with a single line with the dimensions then I mirrored it
Then I started to draw the middle rectangle with it’s dimensions, then I trimmed the extra parts made it not defined
I made a constraint (dimensions)
mirror to this part (Dimensions to be defined )
I drew construction lines to draw the two circles with a distance 89.01 then trimmed the two circles .

Wheel stick DMS

I drew two rectangles with half of the specified dimension

To make the upper part defined i started to put its dimension

Then i mirrored the drawn part

The final shape fully defined

Wheel DMS

-First I drew the circle with the specified diameter at the origin point

-then I drew the rectangle with it’s dimensions

-To make the rectangle defined to the circle constraint(Midpoint from the center of the rectangle on the circles center )

Side holder DMS

I started to draw the rectangle with half of the dimensions , and the smaller rectangle the i added a midpoint constraint

trimmed the extra parts

I drew the other parts of the T SLOT with the same as the first step

Side holder DMS

Fixed points to make it fully defined

Then I mirrored the drawn part

The final shape after being fully defined

Side DMS

I started to draw the left part with the T slot

I started to draw the holes with it's dimensions , then I mirrored the previous step

I drew the other parts with the same sequence

Make constraints (Dimensions and fixed point )

Bow DMS

I started to draw the right part with diameters of the circles

Then I trimmed the extra parts and added fixed points to be fully defined

Then i mirrored the drawn part

Final sketch components

Joining the catapult

First i extruded with a new component

Then I started to join these parts together to the side (Ground )

Mobile holder

Firstly I got inspired from different mobile holders made with laser cutter then i started with the pre activity to design the mobile holder with cardboard , this helped me to know the dimensions i need to make a real mobile holder with the laser cutter , i started to think to make it with another function as to be with a part that can be used to put on it a pencil case , cup ...

The mobile holder consists of 5 parts , with these dimensions

Side holder

Firstly i drew the whole part

I started to draw the T slots , then mirrored it on the same side

I drew the two rectangles on the top then added a constraint (Dimension )

-the same as the first step regarding the T slots , then i fixed points to make in Fully defined

Mobile holder side

Firstly i drew the whole part with Its dimensions

I started to draw the holes for the T slots , and the rectangle on one side with dimensions and fixed points to be fully defined

I mirrored the previous step

Back side

Firstly i drew the whole part with the T slot and holes

I mirrored the previous step to get the whole shape

Added constraints (Dimensions , fixed point ) to make it fully defined

Top side

Firstly I drew the two rectangles and the hole

I mirrored the previous step to get the whole shape

Added constraints to make it fully defined

Joining the mobile holder

I started to extrude each drawing as a new component then selected one component to be the ground which was the side holder

Then I started to join the components together through the assembly panel

The final shape of it

Final shape

Fabrication/Implementation Process

Explain the fabrication/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

To start the fabrication process I prepared the file on laser works , then I went to the lab to start the laser cutting process

-Firstly I imported the file to laser works on the computer connected to the laser cutter , and then click on download

-Then I got the plywood sheet and put it inside the machine

-After this I chose the file on the laser cutter and started to change the origin place from the arrows on the machine to fit the work area, then I started to check the following :

1.If the work area is contains the design or not by choosing the file then selecting track frame

2.The estimated time : After finishing the track frame I chose the file again and selected worktime preview which was 2 minutes

The last thing was to choose the file and click on Run , then I closed the machine .

-After the machine finished I made sure that all the file was cut clearly then I took off the plywood sheet with the design cut in it .

I started the assembly from the side holders and started to connect them with the back part , then connected it with the face of the mobile holder , I had some problems during the assembly because of the location of the T slots , but at the end it worked to be used as a mobile holder but it needed some modifications to work perfectly

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

-Yes I took feedback from the instructors on my work , I learnt from my peers from their questions during the session , as in the catapult drawing someone asked about a specific dimension in a part of the drawing , i had the same problem so I knew It's answer .

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this project?

During sketching I had a problem with making the sketch fully defined , and to add constraints to it , I didn't know which one is appropriate to which part .
I started to relate the sketches to the origin point but this was not a good solution
I returned to the instructor during the session and I knew that when making a point fixed , It acts as a the origin point and makes the sketch fully defined .

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

At this week , I learned a new program (Fusion 360 ) which i will use in the final project to sketch it and import it to the laser works to start cutting it .

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: Pre-activity, examples, exercises, or any mini-projects.
