[WEEK03] Computer-controlled Cutting
1. Group assignment
1.1 Change settings
We tried to use lazercutter with various settings. I took charge of a frequency test. So I cut the simple model, changing a frequency from 1000 to 16000.
| Material | Cardboard |
| Thickness | 3mm |
| Lazercutter | trotec speedy 100 40W |
| Power | 80 |
| Speed | 10 |
| Pass | 4 times | Frequency | 1000-16000Hz |
It seemed that the lower frequency was prefered. I did not expect this.
1.2 Make dimension slot
The cardboads we had were 3mm thick. So I set it as the reference size,and modelled the sketch that the slot dimension was parametrically variable by 0.1mm with Fusion 360.
I set the variables as following pictures to change the size of slot.
I mede chamfered each corner.
I saved it as dxf file and imported to the illustrator to cut with the lazercuter.
I set the parameters as follow.
| Power | 80 |
| Speed | 10 |
| Pass | 4 times |
| Frequency | 1000Hz |
I tried to fit each slots and confirmed that the optimum value of slot dimension was 2.7mm.

2. Indivisual assignment
2.1 Press-fit construction kit
I tried to make object with square and hexagon referring to the space packing model in the nature. The images source was the following picture.This is a drawing of bryozoa(Ernst Haeckel"Kunstformen der Natur"1904)
I modelled three sketches,square,hexagon,and joint parts.
The slot dimension and the side length of each figure change parametrically.
I can make the objects in multiple ways.

2.2 Make a sign on the vinylcutter
Power supply switches of some machines are attatched to the back or side. It is hard to find them. So I made a sign for these hidden switch. This model was made by illustrator.
