Computer-controlled cutting


◆Idea

I want to make paremetric Cube kit.
To make complete cube, the distance of XYZ must be same.
but existing GiK kit cannnot connect to Z axis by itself.

I try to make extra parts. At first, with Rhinoceros.
You can see 3 yellow lines, their length are same.


◆Parametric modeling by Antimony

○ How to export 2D file from Antimony

To export 2D files, use [export] -> [heihtmap(.png)].
You can export 2D Black & White png from 2D date.

When you select 3D model and make png, the shape turn out to be from top view (with shading).


You cannot export 2D & 3D shapes as png at the same time.
If you connect 2D & 3D to one [heightmap] component, 3D shape will disapper.

○ Write Scripts

I want to use math function like grasshopper, but antimony has no one.
But we can write [Script] as you like, and I made +-*/ scripts.


○ Kerf Cutting

Then, I made a curve parts with kerf cutting.
I try some difference parameters(horizontal lines are made by Illustrator).


◆Fabication

First, I try to use fabmodules.
Import and processing is good, but finally cannot send a data to the GCC laser cutter.
I add GCC as a printer via system controll panel in OS X, but it doesn't work.

So I use Corell Draw for cutting.

Machine : GCC Laser Pro.
Material : Cardboard 0.5mm and 0.2mm thickness
(L) is for LaserCutter, (A) is for Antimony Script.

Power(L) Speed(L) Thickness(A) Depth(A) Width(A)
5mm cardboard 75 7 0.45 0.5 5.0
3mm cardboard 50 12 0.2 0.35 3.0

Raw data makes some tightness or loseness.
So I have to adjust parameters in Anitmony.


Curve parts burned while cutting!
So I choose a large distance and down the power(S12,P50), and cut twice.

I notice the orientation of cardboard is important.
Finally, I made this shape.


◆Vinyl Cutter

With CAMEO and Inkscape, I made some stickers.
