Barcelona Port is in the edge of the city where different flows and fixities coexist together. The suggestion that different footage took from the port gave to us was the notion of the border. Boundaries or limits are part of the natural and urban composition that could be considered as negotiators between elements and actions; flows and fixities. The perception of the border is predominant in a port. Besides the idea that a port is the limit between the water and the land, it also means political, urban, social and economic boundaries.

The concept of the first approach we developed from the site was a visual record of all the type of limits we found in the port. The waterfront is a limit between the land and the water that has been shaped through the time. Also we found important to refer Kevin Lynch description of borders: “Borders are linear elements

not used or considered as paths by the observer.They are the boundaries between two phases, linear breaks in the continuity. These border elements are for many people importan organizing featureas, particularly in the role of holding together generalized areas”. For us, this concept is very important in order to understand the image of borders that cities have and maybe rethink it.

How to make a joint for a movable structure?

The design of the articulation started having as a case study the above working model.The joints were designed in order to serve specific movements which will provide the required mobility in the construction.
In order to have full movement, the construction require 12 articulation.
The essential function of almost all the joints is the rotation round an axis. This axis, and the union, are connected to the basic unit on which we can find connected maximum three related extensions.
However it could not be given the necessary mobility in construction if had not designed a central articulation. It’s basic function is to retain the overall grid. In this case the metal bar did not articulate but glide through the joint.

Inspired by Sand dunes formation and its patterns.

Performance
Horizontal Roughing was important to be done prior to the 3-axis Projection Pocketing in order to save time.
The whole process in total took 1 hour.

3D milling – Process consisted of two phases:

First phase:
horizontal roughing
Tool: BallMill 26mm in diameter
Dimensions of the board: 600 by 400mm
Boards of 8mm thickness
Time taken: 9 min.

Second phase:
Projection Pocketing following a rectangular path
Tool: Ballmill 12mm in diameter
Global parameters intol: 0 , outtol: 0.4,
% Tool Diameter: 25 %
Time taken: 48 minutes

Rhino file: steps of formation

Horizontal roughing

The Concept here was to take advantage of the linearity of the board but at the same time break the verticality using horizontal lines. Thus the curves were aligned in vertical direction while the depths were defined using the horizontal contours.

In order to maintain the uniformity in the panel, single Ball mill of diameter 12 mm was used although variation in depths were produced. The experiment here was to go against the nature of the material and see the result. Hence, the tool was designated to run horizontally even though extra effort would be added was known.

Strategy:

Tool: Round Ball mill

Diameter: 12 mm

Maximum Depth: 20mm

Time: 45 mins

Description:

The idea here was to set the design and create a surface using loft of curves in rhino. Later set contours as a distance of 8mm along the required direction. Now, instruct the tool to follow along the contour lines based on the depth.

BIG LASER CUT MACHINE:

SPEED: 50%                        POWER: 100%

SMALL LASER CUT MACHINE:

SPEED: 15%                       POWER: 60%

ENGRAVING:

BIG LASER CUT MACHINE:

SPEED: 50%                   POWER: 30%

SMALL LASER CUT MACHINE:

BENDING:

done manually using a heat gun.

RECOMMENDATIONS:

In order to do the bending and avoid heating, a more thinner material i.e thickness of 1mm and strips of at least 600mm length is required to bring in a similar effect.
