Rapid Prototyping 

From the Ted-Ed talk I learnt several things about rapid prototyping. Rapid prototyping is the process of quickly creating prototypes of your design, with only using basic materials. In the video Mr.Chi only used basic materials such as coat hangers, hair bands, chopsticks, paper clips, clay  and fishing string. Using basic items allows you to be able to create the prototype in a short amount of time, in doing so would allow you to test the product to check for any faults. It gives you more time to troubleshoot how you are to improve your product. An interesting point Mr.Chi made was that there are two types of learning in the world, book learning and expansive learning. Expansive learning is the type of learning which allows you to explore “the realm of possibilities” as Mr.Chi puts it. Expansive learning allows you to utilize your more creative side; giving you the ability to explore all of the potential possibilities for your design.

Project #2

My idea for my second project is too design and create a toy box for one of my cousins. Above is two designs I had in mind depending on whether I do for my girl cousin, Grace or my boy cousin, Lennon. I plan on interviewing their mom and asking specific questions about the designs on the box, I want to include things which they like. I plan on asking here about the shape, this will depend on where she wants to place it in her home; for example, if she wants it square or circular. I will need to get measurements from her to see what size she would like the toy box. Once the interview I conducted I will draw up more specific designs for the final product. Some constraints in which I may face is that with the designs and negative spaces, I need to ensure the there is a lot of positive space to ensure the wood stays strong. Another constraint in which I face is that I am not able to take the measurements myself because of social distancing, I have to rely on my client to be able to correctly take the measurements in her home.

Write Up!

Joinery

The material I will using for the toy box is baltic birch and this type of material is usually thicker than the material we usually use. Therefore, we would need to find a different type of machinery because the laser cutter we have in school may not be able to cut through the baltic birch. The type of baltic birch I will be using will be 12mm in thickness.

CNC Machine

CNC – Computer Numerical Control – Taking digitized data, a computer and CAM program is used to control, automate, and monitor the movements of a machine. The machine can be a milling machine, lathe, router, welder, grinder, laser or waterjet cutter, sheet metal stamping machine, robot, or many other types of machines.

More Research on Joinery.

With doing more research on the joinery I would be using, I have discovered that the designs above will not work out if I plan on using the CNC router. I believe I have faulted in the extrusion and assembling the piece as when I went back to redo it the boxes looked different. The CNC router we would be using in school would have a quarter inch bit on it – because I am doing mine units in cm it would be 0.635 . From a youtube video I learned that with using this bit it usually works out to make the radius of the bit 10% larger – therefore the radius in my designs would calculate to 0.6985. I will be using the dog bone fillet – this particular fillet places the radius in the corner, therefore allowing the two faces to meet each other. Doing this I will draw a 45 degree angle from the corner of my finger joint and then going back over that line I will draw the size of my radius. By using this fillet it allows me to preserve most of the wood. Because I will need this box to be heavy duty and support the wood I can fill in the gaps from the circles with glue to give it that extra bit of support.
