WEEK 2
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)
Baby Elephant Mobile Holder
My mother loves to document any useful information related to her interests and studies so she needs to have paper and pens during using her mobile phone
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
Machines:
Laser cutting machine: Malky Laser cutting ML64 Technical Specs: Working Area: 400mm x 600mm, Laser Power: 60 Watt,Max moving speed: 500mm/s
I used it to cut and engrave the clock
Materials:
MDF wood: according to Wikipedia : 'Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure ' it is suitable material for laser cutting.
Softwares:
LaserCAD software :according to buildyourcnc website: LaserCAD is 'The software that allows communication between the computer and the laser cutter controller, but it also allows you to draw geometry, add text and images and download that file to the laser cutter controller. ' resource of informaton Here
I used it to prepareDXF file
Autodesk Fusion 360 Educational license: Fusion 360 is the first and only integrated cloud CAD, CAM, CAE, and PCB software platform of its kind
I used it for sketching 2d object and export dxf file
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?
Sketches
Components after Extruding
Assemble
laserCAD
I searched on Pinterest for inspiration and found the baby elephant mobile holder so I decided to start sketching from scratch by imaging the components of the design. I used my mobile as a reference for measurements as well as my pen holders
After finishing sketching, I extruded them, made rigid joints and exported the DXF files
I edited the files on LaserCAD software for proper settings for cutting (speed 15, power 75 )
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?
After editing on LaserCAD (speed 15, power 75 ), I saved the files in a proper format (*.plt) link and transferred it to the lab computer that connected to machine then send download order to get ready for cutting
I adjusted the placement of the MDF sheet and turned the machine on.
Clicked on 'origin' then 'box' to ensure the working area then I clicked start.
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)
I found difficulties in defining the sketches in some points and lines but the solution was remaking despite of consuming time (unfortunately I forgot getting screenshots)
The dxf files shows that the side component wasn't completely connected. the solution was manually connecting the separated lines
3. During assembly for all parts, I found some sort of errors leading to failure of joint formation between the side part and the bottom part. The solution is shown below.
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
After training on the Fusion software and understanding the concepts, this will help me in designing 2d sketches using fusion 360, exporting dxf, adjusting settings like cutting speed and power on laseerCAD software for building the final project construction parts
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
I am so glad that I learn the basics of Fusion software.
