CAD-KEYCHAIN &HANDPHONE STAND

Reflection on Keychain recap activity:

 Before I start using Fusion360 to design my own keychain, I need to know its purposes.Fusion360 is a cloud-based CAD/CAM tool for collaborative product development. Fusion 360 enables exploration and iteration on product ideas and collaboration within a distributed product development team which combines organic shapes modeling, mechanical design, and manufacturing in one comprehensive package.

I have used Fusion360 in the previous module CP5065 to make a keychain with my name engraved on it, a photo frame, and our own chemical product. Although I have the experience of using it, I have forgotten some of the basics in Fusion360. Hence, this lesson serves as a recap for me to familiarize the use of this software again.
I have used the guided resource from Youtube provided by the lecturers on Blackboard to start on my task. Click HERE.

Once Fusion360 is opened, it will straight away lead you to an untitled project. The steps for designing a keychain will be explained below with the aid of visuals.

Firstly, click on Create a sketch at the 'CREATE' tab and selected a plane. Then, click on the
2-Point Rectangle and draw a rectangle with a dimension of (65mm by 25mm).

Once the rectangle is drawn, select the Offset option at the 'MODIFY' tab and click on the rectangle. Offset the sketch for about 2mm.

Next, select the Fillet option at the 'MODIFY'tab and click on the 4 outer corners of the rectangle. Type in 5 mm in the fillet radius to create a fillet of 5mm at each corner.

Then, click on the SOLID line at the 'CREATE' tab and create a vertical line by dragging the line from the upper line to the lower line of the rectangle on the left side. Then, right-click on the line and select Normal/Construction to have a vertical broken line.

Select Dimension from the 'CREATE' tab and click on both the vertical line and the outer left side of the rectangle to define a 7mm distance between them.

Then, select Point from the 'CREATE' tab and create a point at the middle of the vertical broken line. Then, select Center Diameter Circle from the 'CREATE' tab and draw a 5mm circle from the point that was recently created. 

Select CREATE Text and align the text position at the middle of the rectangle. Then, type your name with the font Impact and finally adjust the height of the text to fit the rectangle. Center your name accordingly.

Click Finish Sketch. Extrude the base of the rectangle for about 3mm.(Make sure to not select the hole) Hide all bodies from the browser at the left corner of the screen and show your sketch.

Select the Border and your name and Extrude it for about 1.5 mm. From the extrude menu, select offset plane and enter 3mm. Then, click on the 'eye' icon in the browser to show all bodies.

Finally, Hide your sketch. The keychain is designed!

CONCLUSION: CAD is something that I am still quite new at. However, I enjoy the process of learning, and Im looking forward to expanding my skills in it.

Reflection on Handphone Stand Parametric Design Activity:

Week 2 comprises lessons about laser cutting and to help us prepare better for it, we were tasked to create a personalized handphone stand in Fusion 360. However, this time around, it was not an ordinary task of creating a product, instead, we had to apply the parametric function in this sketch. I learned that parametric modeling is a method where we use parameters to set the dimensions of part or all of our model. The interesting part is that after the model is completed and given that everything is in order, we can go back and change the parameters. The model will then change accordingly while still keeping its shapings intact.

Hence, to put our knowledge into action, we had to create a handphone stand with this feature. For starters, I searched through Youtube for guided tutorials on how to design a handphone stand. After viewing and attempting some of the methods, I found the right video for me where it was much easier for me to complete my task. I followed the steps provided in this VIDEO and followed through with some of the steps to get the product that I wanted. I find this feature from Fusion quite helpful as it can come in handy in my capstone project especially when there is a need to change the parameters of the product without having to do it all over again. I find this lesson very useful because in the past I used to think that we have no other choice to change the parameters and had to redo the whole product from scratch. But knowing that this feature exists, I can now predict the amount of time that can be saved in the future. I will definitely make use of this knowledge learned during my capstone project.

Following are the steps to create a phonestand:

Step 1: Add Parameters by typing in the Phone length, width, thickness, angle and offset values as shown in the picture at the 'change parameters' under Modify tab.

Step 2: Right-click on '(Unsaved)' under the browser on the left side of the screen and click new component. Add new components named Phone. Repeat for another new component named 'Stand'.

Step 3: Press on the 'Phone' component and create a new sketch of a 2 point rectangle and bring it to the midpoint by clicking 'Midpoint' under the Constraints tab. Edit the sketch dimension of the rectangle by clicking on the 'P_L' and 'P_W' that we have keyed in the parameters earlier.

Step 4: Finish sketch and extrude the rectangle to 'P_T'

    Step 5: Press 'M'  for move/copy and follow the settings shown and type 'P_Angle' for its angle.

Step 6: Click on the 'Stand component' and create a new sketch using the right view. Press 'P' for  project, click the body for geometry (in blue) and the selection filter is bodies. Draw a line that is perpendicular from the midpoint's width of the rectangle drawn(triangle indicates that it is the midpoint) and press D for its dimension.Type 'P_Offset'.Click on the line and press 'X' for construction. It will show a dashed line.

Step 7: Create a 2 point rectangle and click on 'Coincident' under the constraints tab. Then, click on the bottom length of the rectangle and the bottom line that is drawn. Click coincident again and click on the top line drawn and the left width of the rectangle. Press D and type the width dimension for the rectangle as 4mm and length as 'P_L*0.6'.

Step 8:Click 'Center point arc' under the Create tab and follow the steps in the picture by clicking 1 , 2 then 3. Do the same for the other arc.

Step 9: Draw the lines circled in the picture under the Create tab. Then, under the constraints tab click coincident and click on the upper arc and the midpoint of the rectangle on top of it with the triangle.

Step 10: Click 'Equal ' under the constraints tab and click on 1 and 2 in the picture. Then click equal again on 2 and 3 in the picture. Press D and follow the dimensions of 'P_Offset'.

Step 11: Draw another rectangle as shown in the picture .Under create tab, click '3-point arc' and make 2 arcs like in the picture.The end of the arc must be touching the bottom length of the rectangle.

Step 12: Click 'Concentric' and click on the white dots on the right. Then click the equal under constraints and equalize the two circled widths.

Step 13: Press D and type in the dimension as shown in the picture. For dimensions between the arc, right-click the mouse and 'Pick circle/arc tangent'.Type D as P_L*0.6  as the length of the bottom rectangle.

Step14: Click on the change parameters under Modify tab and edit the dimensions as you wish.

Step 15: Finish Sketch and click on the empty space on the screen and drag your mouse on the middle part of the sketch and press E. Extrude the middle part with the dimension 'P_W*0.45'.

Step 16: Click on the 'eye' icon of the 'Phone' component to hide it.

Step 17: Finally, fillet the edges of every sharp corner of the handphone stand by 2mm. 

The finished phone stand should look like this.*The parameters can be changed to fit into other dimensions*

Below is the 3D modeling of the phone stand:
