Week 3: More Desktop CNCing


We’re continuming our work with the desktop CNCing.  We will discuss more material, endmill, and file options.  As well as start working with CAD.



A great source of inspiration is to use existing files for your 2.5D parts.  Pulling files from the Noun Project.


Different Bits

There are a lot of types of bits: round nose, engraving, small bits.  And fan attached.


Different Finishes

Aluminum: Sanded, Polished, Tumbled, Powder Coated
Plywood: Sanded, Oiled, Waxed
Acrylic: Waxed (1st stage wheel only)


Milling Thin Parts

Thin parts using PCB spoilboard

Step 5 in Build a Magnetic Clock



Slip Roll Metal Parts

If there is times, we can show the slip roll for curved metal parts.


Vacuum Former

If there is time, we can show you how to form plastic shells.


Vector Works

For the time being, our CAD (Computer Aided Design or Drafting or Drawing) of choice will be VectorWorks.  If you haven’t already, please download the free student version.

Again, we will stick to 2D drawings for now in order to create 2.5D parts.  Simple drawings can turn into involved parts.

The 2D Polygon Tool can make complicated geometry very quickly from simple shapes.



Make something involved on the mill.
