Week03-Computer-Controlled Cutting

The homework this week has two types, individual assignments, and team assignments.

Group assignment:

Characterize your lasercutter’s focus, power, speed, rate, kerf, joint clearance and types.

Document your work to the group work page and reflect on your individual page what you learned.

Individual assignments:

Design, lasercut, and document a parametric construction kit, accounting for the lasercutter kerf, which can be assembled in multiple ways.

Group Assignment

In this group assignment, I learned for the first time that changing the pattern can alter the curvature of the wooden board. It was very interesting for me.

2. Individual Assignment

2.1 Design a parametric construction kit

2.1.1 Parametric Modeling

I will use Fusion 360 to design my kit-Snowflake pieces.

First, I use parametric modeling to create a hollow circle.
Next, I used the “Center Rectangle” command to draw a rectangle with dimensions 13 * 2.
Thirdly, I used the “Circular Pattern” command to copy 10 rectangles around the center.
Fourthly, after completing the sketch, I extruded the shapes.
Finally, to make the snowflake more aesthetically pleasing, I added fillets.💯

In addition, I also created another “snowflake piece” to expand the variety of shapes.

First, I created a model using “Center Rectangle” and applied parameters.
Second, I used “Center Rectangle” and “Rectangular Pattern” to create slots. The width of the slots and the slot width of the snowflake piece were set to the same parameter.

Finally, I set the thickness of both snowflake pieces to the same parameter. This way, by changing a single parameter, modifications can be applied to both models.
