Group 15_ Milled Collage

Our purpose is to create a contrast between four monochrome surfaces and a multi-colored surface situated in the middle. In the modeling procedure the four surfaces have a slope which causes a shade and at the same time the middle surface consists of distorted pyramids defined through a Grasshopper definition. The pattern of the pyramids allows different colors of valchromat to show. We created sloped contour lines on the four monochrome surfaces which are parallel to the inner edges. For the multi colored surface in the middle, we created dense contour lines on the pyramids.

Valchromat Milling – Group 17

Anya — Thu, 05 Jan 2012 02:18:21 +0000

Concept

The idea was to create a geometrical pattern which can change and be perceived as a different volume from different angles. Leonardo da Vinci drawings were our inspiration. The object consists of 50 mm cubes and in each row the cube touches the adjacent cube in its corner (intersection point) and they have one parallel continuous diagonal line for the whole row. The rest of the rows are the same but it is shifted half the diagonal length to one side to intersect the cubes corners with the previous row intersection points.

Milling strategies
• 2 Axis engraving milling.
• 12mm radius tool.
• Maximum depth reached was 22mm.
• Process took 40 min to finish.

Milling Information

Infomilling

Because of the specifications of the Valchromat material, and because we could use different tool sizes we thought that this assignment is a very good way to display information. We decided to display information about laaC students, specifically their origin.
So we placed a worldmap on top of our piece of material. We placed laaC in the middle, and put points on top of the countries where the laaC students come from, then connected these points with IaaC.
We selected the depths of the cuts in the way that, on each “crest” is on a different color level, so circles and straight lines are drawn by colors.

MILLING IN VALCHROMAT

swetha — Sat, 31 Dec 2011 17:48:19 +0000

The milling exercise was developed to make us familiar with the milling machine and explore the myriad ways of using a multi layered and coloured valcromat panel (our assigned material for milling).Developed on the concept of “Abstract depicting of the properties of a silk cloth” ; 2 tools, a 26 mm flat edge tool and later a 12mm tool was used for parallel finishing to achieve the desired effect.

Time taken : 1 hour and 10 min.

Milling in Valchromat

The exercise consisted in generating a pattern on a valchromat board sized 400 x 600 x 240 mm, by using the CNC Vertical Milling machine. We explored the different effects and tools the 3-axis milling machine offers by simulating a number of patterns in RhinoCam for Rhinoceros. Our final proposal consisted in a series of nurbs inspired in water ripples, they were generated by heightfield and booleaned tools into the panel, then this geometry was milled by a 26mm ball mill for horizontal roughing, and later detailed by the same tool as the previous process, but used for the parallel finishing.

The Crater

The main goal of the process was to study the Milling process and use the 54mm Ballmill to explore the different layers of the Valchromat panel by subtraction method.

By creating a pattern of curves in Rhino3D we used the curves as toolpath in RhinoCAM to simulate the process. The entire milling process took 40min.

Contouring valchromat

Akhil Kapadia — Fri, 23 Dec 2011 23:38:06 +0000

The concept behind the project was to exploit the 3 layer property of the valchromat panel, as well as to understand the tools being given and achieve an effect using the tool to our advantage. We wanted to do something which would take a lot of time to model in rhino but because of the rhinocam simulation would create a greater effect in a shorter time. We were inspired by the forms of layered rock and started analyzing how we could achieve a contoured layered effect whilst exposing the different coloured layers.

The modelling in rhino was done using the ‘heightfield from image command’. Some scaling and mirroring was required to fit in the model in the given constraints of 595 x 395 x 24 mm. The tool used was a 10mm diameter flat end tool. The stepover and offset controls were tweaked and played with in order for us to achieve the layered effect that we desired.

Considerations that we made for the material were that it might be fibrous and brittle inside so we were depending on the tool to be sharp and precise. This was not so and therefore our milled panel was a little hairy. We fixed this by finishing it with sandpaper.

We used only one milling strategy – horizontal roughing. We had no need for any kind of parallel finishing for the contoured layered effect that we wanted to achieve.

Project data:

Tool cutting speed: 20.32
Tool spindle speed: 6092 rpm
Milling time : 107 mins

DIGITAL FABRICATION ::: EXERCISE 2 – Valchromat milling ::: GROUP 19

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

Horizontal roughing

Students: Fernando Barba/ Jose Starsky Naya Lara / Ricardo Fernandez

In this project we wanted to emulate the idea of a topography based surface, our intentions were to simulate in RhinoCAM the capacity of the machine to build this gently shapes in order to obtain the result we wanted, Valchromat was picked and its intended to watch the depth of the material by trying to show all the three colors of the panel first doing a 26mm tool Horizontal Roughing to remove the most quantity of material and then pass to a 12mm Parallel finishing tool for a better smooth looking surface.

Scales : Milling

lana.awad — Fri, 23 Dec 2011 07:09:15 +0000

The inspiration for this exercise came from the undulating scaled surface of fish skin. The geometry of the panel breaks from the repetitive nature of real fish scales by the introduction of a point of distortion. This point of distortion is further emphasized by using particular milling strategies.

In order to achieve the desired form, two milling finishings were used. The first strategy used was a parallel finishing. The tool diameter was 12mm ball mill with stepover control as 35% of the tool diameter. The spindle speed was set to 8077 and the cutting speed assigned was 15.24. The total time taken for this strategy was 70 minutes. The second finishing was a radial finish using the same 12mm dia ball mill tool with stepover control as 150% of the tool diameter. The cutting speed assigned was 15.24. The entire mat took 40 minutes to mill with this finishing.
