Week 2- Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

This week's assignment is to make our own design of a simple mobile holder on Fusion 360 software and prepare it for laser cutting.

Inspiration:

I needed a phone holder that looks cool and have a joint for more options. Also I thought first to make an option to gather all my stuff (i.e. phone, sticky notes, accessories, etc.)

I browsed google.com and mobile phone holder website for laser cutting free vector models to form an idea. I came across these designs while show me the motion joint i needed then I start to look for my own design. I'd prefer to position my phone at different angles depending on whether I'm viewing it in portrait or landscape modes, and how high is the phone locate.

Besides that, I tended to change the basic normal design into a design that I like.


Tool Chain

Which software/machines/materials did you use in the assignment? Why?

Software:

We'll be using Fusion 360. in working this week, we'll be focusing on designing and creating the phone holder's parts of on Fusion 360.

First we'll create a 2D sketch of each part of the phone holder then we'll extrude these sketches into 2.5D parts so we can assemble them to form the final product. Finally we extrude the file dxf. file to import it in laserworks.

Machines:

Laser cutting machine for the fabrication process.

Material:

  • A Plywood sheet

  • M3 screws and nuts

Fusion 360.

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

  • As I mentioned before, I love the way the cat act in different ways. I search for a way and a picture that came to my mind. Then I used my pencil to sketch my own design, After that, I used Fusion 360 software to turn my sketch into a fully defined dimensional 2D sketch.

  • A fully defined sketch is one where all the dimensions are specified from a certain point or fixed-line so that your lines don't accidentally move while you're working. To indicate that a line is defined, Fusion 360 will change its color into black. Our instructor pointed out that an easy way to make sure your sketches are fully defined is to start sketching from the origin point of the plane since Fusion 360 already has this point defined and fixed.

  • After sketching finished and closed its area should turn blue Which indicates. If it doesn't, while in sketch mode, make sure all the points are connected.


sketches in fusion 360.

  • First I insert a picture of a cat to make a guide.

then I start to draw with fusion features (line &arc)

  • Moving to the Side of mobile holder I measure the size of the needed phone and make the side could fit it and more.


  • Second I draw the connection components with arc and lines by also using mirror features to make it easy.

  • Last part was the back of the mobile, I draw half the part then mirror it.

  • The T-slot for connection

  • I struggled to make the Spline fully defined, so I was told to set a measurement for all the handles, and I also found the same problem in curves but I was told by the instructor to try the other parts and I tried doing fixed lines and make the other defined. Finally I do it to some parts.

Try to make it fully defined

The back part and the two sides parts' sketch is fully defined in Fusion 360

  • Finally after I draw the base part and the main components and extruded it, using "3D sketch preference" extruded it into 2.5D.

  • I made the T-slots where the main parts will rest, I imagine the moving joint how I could be, After that, I assembled all the parts together with rigid joints, and I checked that the T-slots and the screws circles are identical and matched each other.

  • First extruded all the parts into 2.5D.

  • Third assembled the moving joint with the back part

  • Import dxf. file of the parts to lasserworks program

  • Then arrange it in the sheet then save the file rd.

Finally take the file (rd.) to the laser machine

  • Second start to assembled the back part with the sides

  • Forth assembled the cat body with the joints.

  • Cut:

Color: Black Speed: 30 mm/s Power: 65%

color: Blue Speed: 150 mm/s Power: 65%

  • Engrave:

Color: Red Speed: 150 mm/s Power: 10%


Development/Implementation Process

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

  • First we save the file rd. file in laserworks, then we transfer it to flash memory then put it in the machine.

  • Using the Laser machine was quite easy as we learned before, I follow the steps for manufacturing.

  • Then The fabrication process was done then I assembled the parts together to check the dimensions but I found a problem in the joint connection but I asked my brother for help and we find a solution.

The move of the joint

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

  • First I was not sure about the scale of the design.

I tried different scales, I Try to do it with crafts and paper before laser cuttings, finally the design is came to the end.

  • I also found difficulty in making the Spline fully defined cause of the curves.

  • During the process I face a problem in the joint of the component. I tries different size of nails, I need a nail more taller than that in the game kit then found a suitable one.

solution and the instructor's advice :

  • First I try to make fixed lines around the parts to make the parts fully defined also the instructor advice me to use the origin point as a reference for the sketch and it works.

  • I found a different size of nail in my home to fit the parts and to make it move up and down for the joints.

Final Project

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

  • Being able to draw the ideas about the design and translate them into a scale draw and a viewable model.

  • Exploring Fusion 360's features to make fully defined sketches of the design.

  • Understanding the connection to assembly the 2.5D parts of an object.


WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

  • I have learned how to use the damage parts in another process, how to think of what you can do in a different way. It's so cool to try a piece of wood in different way that you never think about.

  • Also I'll never forget that at first I was disappointed when I try to collect the parts of the assignment but I couldn't, then I try to use a different joint that make the connection better than I thought.

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.

We distributed the chair's sketches between us to draw them in Fusion 360, then we assembled them and we face a problem in the side view but the instructor help us to prepare the parts for laser cutting fabrication using LaserWorks software.
