INTRODUCTION

Machine: CNC milling;
Density: 80%;
Topic: Structure performance;

The mission of digital fabrication phase2 is finish 6 plaster bricks. The moulds are manufactured by CNC milling. Our group chose high density foam as the mould material, which has a easy milling processing. In this project, we tried to built a relationship between force analysis and texture, meanwhile we explored how to generate different texture with milling bits.

REFERENCE

CONCEPT

The idea is to establish the structural stability through deformation of force lines caused by the voids at specific locations in the module.

1.Taking the Forces from the above bricks

2.Placing a void in the centre (hyperbolic shape) has a non uniformly distributed stress.

3.They are again deformed by arches on the top and bottom.

4.The stress lines are engraved on the brick which forms the texture on its own.
