Class 2: 2D design and Cutting

2D Cutting:

Our project in this class was to create a press-fit design. This could be anything from an abstract sculpture to a sophisticated box. It just had to meet a few criteria. No adhesives Design using CAD and laser cut

Tolerance Test:

For my project, I knew that I would need to know what tolerances to use so everything would fit together snugly. I decided to 2D model a test for all the different press fit connections I could use.

After I printed out the piece I wrote notes on one of the pieces and used this to better my future designs. Cad of Test

Abstract Sculpture:

After testing I decided that I wanted to create an Abstract Sculpture.
I looked at some previous designs for inspiration like this one, and then I decided on a shape.

Process:

I knew that I would have to have many of these pieces so I also created a sketch with many of these shapes.

I then laser cut out all the shapes.

Then I assembled my shapes into a 3D object!

Final Sculpture:

Intro To Cad:

CAD (computer-aided design) is a family of software that allows engineers, creators, architects, etc to precisely digitally model objects.

This week we learned the fundamentals of CAD and did three things.

Used a tutorial to learn how to 2D Sketch
Created 2 household objects and put them in an assembly
Designed a press-fit object, 2D modeled, and laser cut it

Tutorial:

This was the tutorial I used: Fusion 360 Tutorial for Beginners - 1.
I used Onshape to complete this tutorial as I am more comfortable with the program.
In the tutorial the instructor had you create 3 shapes using many different tools.

Drawing 1:

Note: For this shape, I had to add a construction line to constrain the drawing properly. I think this is something to do with the fusion 360 vs Onshape programs
Tools Used: line, arc, dimension, construction
