Keychain

Hello everyone! For the first lesson of CPDD, a recap of Fusion 360 was done in class and everyone was required to create a keychain, similar to what we had done last semester. Here are the step-by-step procedures on how the keychain was made using Fusion 360.

1. First, create a sketch and draw a rectangle of 65mm by 25mm.
   

2. Secondly, using the offset function, offset the rectangle by 2mm.
   

3. Thirdly, using the fillet function, apply it on the 4 outer corners of the rectangle and enter 5mm for the fillet radius.
   

4. Next, create a line and draw it closer to the left side of the rectangle. After that, right click on the line and select ‘Normal/Construction’.
   

5. Next, using the dimension function, click on 2 lines, one being the left breadth of the rectangle and the other being the new line which was constructed in step 4, and create a 7mm distance between them.
   

6. Create a point in the middle of the line. Draw a 5mm circle from the point.
   

7. Next, create a text, type your name in the text box and adjust the size and fonts of the letters according to your preference.
   

8. After that, click on ‘finish sketch’. Then extrude the base of 3mm (Do not select the hole). Hide all bodies from the browser and show the sketch by clicking on the ‘eye’ icon.
   

9. By selecting the border and your name, extrude them by 1.5mm. From the extrude menu, select ‘offset plane’ and enter 3mm. Click on the ‘eye’ icon to show all bodies.
   

10. Lastly, hide the sketch.
    

Here is how the final product should look like.

Reflection:

In this lesson, I had to use Fusion 360 to design a keychain. This activity serves as a recap of what I did last semester in ‘Introduction to chemical product design’. This task was important because it helps to brush up my Fusion 360 skills and be more familiar with the functions so that I will not forget what I have learnt. This is useful for the project in CP5070 as I can be more confident in designing my own desired product. I used to think that I would not be able to apply Fusion 360 in my projects frequently and it was a waste of time. Now I think that I can see how I will apply Fusion 360 in my project and how I could use it as a draft before creating my product using a laser machine. So next I will continue to improve my Fusion 360 skills and hopefully create my own product in future.

 

Laser cutting

Hello everyone! This week the class was tasked to create a handphone stand using parametric by designing it in Fusion 360. Here is my take on how I created my own handphone stand.

1. First, create a sketch and click on any side of the plane to start sketching.
   

2. Secondly, fill up the parameters before sketching the handphone stand. Click on ‘Modify’ and then on ‘Change parameter’.
   

3. Click on the ‘+’ sign and fill in the values of any angle or length you desire, depending on how big your product is.
   

4. After filling up whatever parameters you need, it should look something like this:
   

5. Next, using the parametric settings you had just created, the product is ready to be sketched out by creating a line. This is what my handphone stand looks like after sketching.
   

You will realise that imputing the values for different angles and length are not needed. Just by simply entering the name of the parameter you give, the angle or length automatically appears. 

6. Click ‘Finish sketch’ to view your handphone stand without the dimensions.
   

7. Lastly, extrude the handphone stand by any dimension you desire using the ‘Extrude’ function under the ‘Create’ tab.
   

Here is how the final product looks like:

Reflection:

This week I had to create my own handphone stand using parametrics. This task is important because it helps to refresh and brush up my Fusion 360 skills. The task is useful for my project in CP5070 as it allows me to explore the different functions in Fusion 360 and make me see how I can apply it to future projects. I used to think that using Fusion 360 was troublesome and would differ a lot from what I desired my draft to look like as compared to hand drafts. Now I think that it is much faster than hand draft and it is rather accurate to what I want my draft to look like. So next I will continue to use Fusion 360 to help me draft future products for my projects and improve on my skills.
