Week 2 - Journal

idea from video design No.3, it is a shared mobile holder. make it from cardboard in a hands-on activity, I try to design it on Fusion 360.

1. first, get the dimensions of all parts from the cardboard design.

2. make a design on fusion 360.

3. start with the Bottom shape

• draw a square with dimension (100*100 mm).

• have four symmetric holes and slots.

• draw construction lines in the center of the square.

• draw hole (3.2 diameters), rectangle slot (20*3.2 mm), mirror those around construction lines.

1. first, get the dimensions of all parts from the cardboard design.

2. draw the front shape:

• draw a square with dimension (100*20 mm).

• draw construction lines in the center of the square.

• draw T-slot with dimensions from here, and put it in the center.

• rectangle slot (20*3.2 mm), mirror this around construction lines.

• double it from copy and paste.

1. first, get the dimensions of all parts from the cardboard design.

2. draw a triangle shape

• with dimension (75*60 mm).

• draw construction lines in the center of the square.

• draw T-slot with dimensions from here, and put it in the center.

• rectangle slot (25*3.2 mm), mirror this around construction lines.

• double it from copy and paste.

1. first, get the dimensions of all parts from the cardboard design.

2. draw bridge shape

• draw a square with dimension (90*35 mm).

• draw construction lines in the center of the square.

• rectangle slot (25*3.2 mm), mirror this around construction lines.

1. choose the extrude icon.

2. select the bottom part and give it a 3mm thickness.

3. Do these steps with all parts with the same thickness.

1. choose the joint assembly icon.

2. select the square face in the slot of the side part and the square face in the hole of the bottom part which will be joined together.

3. make the same steps of another side with the bottom.

4. select the square face in the slot of the triangle part and the square face in the hole of the bottom part which will be joined together.

5. make the same steps of another triangle with the bottom.

6. select the square face in the slot of the bridge part and the square face in the hole of the triangle part which will be joined together.

7. make the same steps of another triangle with the bridge.

8. now all parts are assembled successfully. yahhh

1. choose the sketch 1.

2. right click and choose save as DXF.

3. Do these steps with all parts.

1. import DXF files (Bottom, Side, Triangle, bridge) to Laser Work.

2. delete any construction lines.

3. move parts close to each other to the corner of the sheet.

4. copy shapes of (Side, Triangle)

5. adjust the speed and power to all of the parts to cut it.

• speed: 25.

• power: 70.

6. save file as .rld

1. make sure the setting of the design is correct.

• power 65 to 70

• speed 25

• download the file to the machine.

2. put a wood sheet in the machine.

3. set the origin of the laser beam.

4. making sure the focus is right.

5. choose the file and run it.

seeing a shifting line for design, But this is not a cut line it is a small graving line, happened because of laser alignment, and the machine was cleaned before I used it.

These lines did not affect cutting and all parts assembly successfully.

the curve base of the chair was cut as a single piece not a piece of the side of the chair. (I used glue to fix it)

to solve this problem use the trim tool in fusion 360 and cut the selected line

Drawing parts as a team then assembly it, and make one part it is really fun to me
