MILLING: CONTRAST

By akram.salah | Published: December 22, 2011

In this milling exercise we tried to create a panel that would show the contradiction between a smooth surface and a more machine made- industrial set of drilled points. We used a surface as the starting point and on it we traced a set of irregular curves that went through only the first layer of our valcromat panel. For this first strategy we selected the 54mm ball mill in order to produce a rather smooth surface at the boundaries of our curves. Moving on we selected a second set of surfaces and from these we produced points that we then used for our second strategy. This time we used the 10mm flat mill and we tried to go through the second layer of the material to bring out the contradiction of the techniques even more.

1st Strategy – Engraving on curves – Tool : 54 Ballmill – Duration : 45 minutes
2nd Strategy – Engraving on points – Tool : 10 Flatmill – Duration : 20 minutes

Bending Paper Lamp

The task was to figure out a design by the basis on the technique of bending and a material that was cardboard/papper. Our design implements the concept of one-piece/self-supporting structure that could spread light creating an atmosphere for diverse kind of spaces.

We tested several kinds of material and cut more than 2 times in order to explore the characteristics and select the best for the purpose of design. Our first tests had some engraving to manage the curve but at that time paper kind of broke because it was to hard to manipulate, another issue that we had was about how to fix together by this kind of arms-structure, they just disengaged from the main body. The design of the Lamp was made on Rhino modeling software, but we started doing some tests from shapes in different kinds of paper and bending. The cutting procces using a lasser cutter machine had these characteristics. Cutting process: Speed= 60 Power=80.

At the end we selected a kind of cardboard flexible but with the strength enough to resist itself in a single piece bended using kind of sticks folded from the central piece of paper.

Milling: Curves

By ranjini.manimudi | Published: December 22, 2011

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.

Lamp: Metacrylate

By ranjini.manimudi | Published: December 22, 2011

The experiment aimed at understanding the behaviour of material with bending technique and what limitations we have due to its thickness. Hence with a 3mm thick transparent metacrylate, we created a lamp which explored in variations of curves. The variations were brought by changing the distance of hole and length of strips, thus proportionately varying the domain.

Parameters followed:

CUTTING:

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:

SPEED: 15% POWER: 15%

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.

3D Printing // Spring Joints

By deniz.tumerdem@iaac.net | Published: December 21, 2011

Our main purpose is to test the bending capacity of the material according to different forms. The starting point was the plain form of a spring and its multiple profiles. This allowed us to test the different possible geometries and come to conclusion on which of them have more capacities on extending, bending and supporting rigidly the structure. The forms were modeled in Grasshopper and as a consequence they could be changed with different parameters like the number of turns of the helix and the dimensions of its profile. Continuously, we developed a new form which derived from this knowledge. This joint consists of an outer deformed helix which is connected to two inner ones which hold the 6mm bars. The parameters which influence the final printed forms is the maximum diameter of the center of the helix, the number of turns in all the three of them, the dimensions of the swiping profile and the height of the inner ones. From start the form which can be achieved using these joints and flexible bars was a geometrical form which could be deformed in a flexible way. That is to say, after deforming it, it can get back to its original shape.
