3. Computer controlled cutting¶
This week I worked on laser cutting and vinyl cutting. At first, a group assignment was done.
Group Assignment¶
In the group assignment, the effects of changing speed or changing power in a laser cutter were observed.
As you can see when the power was only 20%, the polygon was not cut.
Joint clearance test¶
We have also done a test where we changed the thcikness of a hole on one cardboard, and see whether it will fit as we increase or decrease this thickness.
Individual assignment (laser cutter)¶
The task is to use the laser cutter to make something that can be assembled in many ways.
I got insights from things like a “deltoidal icositetrahedron” or “trapezoidal icositetrahedron”.
So, I decided I will make two shapes in fusion, one shape is a triangle, the other is a join, and then print a large amount of triangles and joints, to see eventually what kind of shape I can make with them.
I started by sketching in fusion, 360, I made the triangle, made holes in it such that the joint can be inserted.
Then we made it by the laser cutter:
Result¶
The hole was bigger than the thickness of the cardboard, so since the design is parametric, all I did was change parameters such that the carbdoard would fit.
#### Result
This time it worked, and I managed to make a shape out of it:
That last one, does it remind you of anything?
Personally it reminds me of the one and only:
The Black Pearl.
Individual assignment (vinyl cutter)¶
Now that we made the black pearl, let’s make an anchor for it.
I started by searching for an Anchor clipart image on the internet, and found this:
I went ahead and inserted it in Fusion, then I drew on it.
And then I imported the drawing to the software associated with the Vinyl Cutter “Cricut Explore Air 2”:
