Computer-Controlled Machining

Design, produce all over the world.

Computer controled machinig is was the revolution in modern fabrication

And it's principel's gone be the drive for the digital fabrication.

In this week i dicided to build a coat hanger.

Furniture is always a must have in digital fabrication and expecialy in this week.

So i need one and i design and build one. First the design.

In my fablab at penela we have licence to Rhino so i chouse rhino as a design tool. My Background is not design, so i must learn many thing's.

Fisrt e sketch-up the idea with Luis carvão in a Piece of paper.

Then i start to design it on Rhino.

Fisrt the small circule. Dimension's in millimeter's

Then i start to design the foot.

i use a spline and i modelate it until it get's the shape i think that was ok.

and now it look's like this.

After this i make an extrude in booth design's with the thickness of the material. 31mm (in fact the ply wood was 30mm but when we measure it...)

Then e make an assembly of the two pieces and start to trim and boolean split.

a short list of commands After that i "cut" the join and put it in 2 demensiones

Look make 2D command :)

After that i test the joint i machine it in our great machine the Portuguese shopbot Ouplan

I use an 6mm Flat end mill

For machine this i use this parameter’s
