Laser Cutting

Designing the model in Fusion 360

This video explains the process very well.

I will be using my music box assignment as an example

Symbols

The above are my set parameters, which are useful for modifying the length of the model quickly

Symbols Symbols

  • I started with the bottom of the box.
  • First, I made a 2D sketch of a rectangle, and defined its width and length using parameters
  • Then, I extruded the sketch
Symbols

    Moving on to the creation of tabs/fingers along the bottom

  • I created another sketch along the bottom, drawing a rectangle
  • After extruding that sketch inwards, it creates a spacer(space between tabs)

Symbols

Going to Create menu > Rectanglular pattern will create more spacers and tabs along the bottom

Symbols Symbols

Moving on to the side of the box

  • Like the bottom, it is a rectanglular sketch extruded
  • However, it overlaps with the bottom
  • I separated them by going to Modify menu > Combine and selecting the side as my target body and the bottom as my tool, with the operation set to "cut"

Symbols

The rest of the box was made using roughly the same tools

Symbols

I added holes for the lid to be fitted in

Preparing for laser cutting

Symbols

I exported the individual sketches as DXF files and imported them into Inkscape
