3. Computer-Controlled Cutting

This week we start experimenting with the “real” machines! Vinylcutter is the entry to this exiting world, followed by the famous “Laser Cutter”. To deep our toes in them we have to make a sticker and a construction kit in cardboard.

Assignement requirements

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 assignment:

  • Design, lasercut, and document a parametric construction kit, accounting for the lasercutter kerf, which can be assembled in multiple ways.
  • Cut something on the vinyl cutter.

Individual Assignement

1. Vinyl Cutter

First of all we prepared the design file (We use the SVG format for the image we want to cut) and upload it to the vinyl cutter software. fusion 360

After Setting up all the setting on the software SignMaster CUT 3.5 dedicated; we can now load the material into the machine fusion 360

Here’s the control panel of the vinyl cutter and we setup the speed to 100 m/s and the force to 300 g. In function of how deep or fast you wanna go you can adjust the differents parameters. fusion 360

When the cutting is finish there’s two more steps :

  • First : Retire the border from the cut part and just keep the design fusion 360

  • Second : Apply the design part vinyl on a film to help us paste it on a surface. fusion 360 fusion 360

Here’s how look the knife inside the machine. fusion 360

2. Parametric Design Construction Kit

For this assignment i wanted to make a modular storage box kit for our Electronic room here in my LAB because we don’t have some boxes for the storage of small components.

The first thing to do is to define the differents parameters of the kit and after that setting all of them into fusion 360, in the window modify -> modify parameters fusion 360

Design the sketch of the box. I choose hexagonal shape because i love it ! fusion 360

Now we can extrude this shape to the thinkness parameter. This represent the front cover of the box storage fusion 360

now we create the back cover by using the symetrie operation. Before using the symetrie operation you have to create first a new plan from the front face to the half of the total deep. fusion 360 fusion 360

We can now create the cut parts for the side of the box by using rectangular shape and a good use of rectangular pattern. fusion 360 fusion 360

We made the cut to help us just have one motif and duplicate it for the 5 others side by using circular pattern. fusion 360 fusion 360

I also design another part to make connection between many box cut to make them modular. fusion 360 fusion 360

Make all the parts like components and open them in a new fusion file to do the assembly for the animation. fusion 360

Export dxf files from Fusion 360

First of all to do this we have to install the plugins/script dxf for laser cut. Here is the Link to download it. fusion 360

For the installation just launch the executable and follow steps fusion 360

After this we can now go back to fusion 360 and go to : utilities -> ADD-INS ->Scripts and adins -> Addins -> DXF4Laser and the add it. fusion 360

To use it is very simple. Go to Create -> Save DXF fo laser cut and then selet the face you want to export set the kerf to 0 and now you can export. fusion 360

And open it with illustrator to the original size and prepare you differents Job. fusion 360

3. Laser Cut

First step calibrating the distance between the laser and the materail. fusion 360 fusion 360

Make some test to find the good parameters for the marials i’m using fusion 360 fusion 360

Kerf test fusion 360
