“The manufacturing process aims to succesively reduce material from the stock model until it reaches the final shape of the designed part. To accomplish this, the typical machining strategy is to first use large tools to perform bulk removal from the stock, then use progressively smaller tools to remove smaller amounts of material. When the part has a uniform amount of stock remaining, a small tool is used to remove this uniform stock layer.”

CONCEPT:
For the bench we decided on a sculptural look. Considering it was to be fabricated out of plywood we wanted to counter the rigidity of the waffle structure with fluidity of the surfaces. It is designed as a two seats accessed from opposite sides. The interplay of surfaces and heights creates the back rest and seating for each side at the same time maintaining the homogenity of the bench.
PROCEDURE FOR CREATING WAFFLE STRUCTURE OF BENCH:
Step 1: We started with the bench template. Applying cage edit the bench was modified along the control points to the desired shape keeping the two side surfaces intact to allow for connection with other benches. The height and widths were modified within the control box.
Step 2: Once the bench shape was finalised and we ran a check for the following the external parameters of the bounding box, we proceeded with creating the waffle structure to obtain surfaces for the laser cutting. Firstly the various layers were created in the rhino file.
Step 3: First we off-setted the outer surface to the required thickness to have two separate surfaces. Instead of countouring we introduced planes in the X-Y direction. For this a plane was introduced along one end of the bench for planes along the X-direction and arrayed along the length of the bench. Similar thing was done along the Y direction. We now had intersecting planes in both directions.
Step 4: The outer part of the planes were trimmed along the outer surface of the bench to get the outer ring. The inner part of the plane was trimmed along the inner surface of the bench. The trimmed panel was thus achieved in the X direction and similarly obtained for the sections in the Y direction.
Step 5: Changing the layer the planes were intersected to get the lines of intersection between the surfaces in the X & Y direction.
Step 6: Two solid pipes were drawn for X and Y direction, put in separate layers and copied at every intersection – one for the intersection along the X direction and the other for the intersection along the Y direction. The diameter of the pipe was kept as 2.8mm.
Step 7: Using ‘Intersect’ the pipes were intersected with the planes. This was done separately for the planes in the X and Y direction keeping only the required layers switched on.
Step 8: The surfaces were then unrolled using ‘Unrollsurface’ separately in the X and Y direction.
Step 9: the ribes were gruped an arranged on the plywood sheet size of 1.2×2.5m using ‘Rhino nest’. The curves were simplified using Curves Edit tools- ‘ simplify lines and cuerves’ and saved as a .dxf file for printing.

The Institute of Advanced Architecture of Catalonia is involved in a research project to transform the city of Barcelona in a Zero Emission city.
For that, an interactive model has to be fabricated, so design decisions can be made. In this tutorial, we will describe the step by step of how to send the 3D model of the barrios of Camp del’Arpa, La Sagrera, Congrés and Navas, to the milling machine so it could be milled.
After the model was printed in a high density foam, it was inserted in the model of the entire city of Barcelona. The scale of this model is 1/2000, and it will be used as a study model. A final interactive model will be built, and this will help in the design decision.

The aim of this assignment was to create a foam model of our barrio using the CNC Milling machine. We first prepared a 2d rhino file of our barrio which had to be printed in the laser cutter at the scale of 1:5000 and on which we discussed and examined various issues concerning the 3d printing process and the way of union the different barrios (boarders, designing methods etc.). The file comprised the streets, the blocks and the buildings, all organized in one layer in order to be engraved. The boarders of the barrio were organized in a second layer determining the cutting lines.
We created the 3d rhino file using the required information from the web and we organized the buildings in layers, according to the number of floors of each building, giving finally the corresponding height. We added the 3 cm base of the model and the 2 mm height sidewalks and we changed the scale into 1:2000. We converted the polysurfaces into meshes and union them all together.
A barrio (Camp de l’ Arpa) that has not been previously allocated to any of the groups was added to ours a posteriori. Finally, the model was printed successfully in one piece. Because of the different height of the materials, we had to cut our piece through horizontally manually, in order to fit with the neighbor areas.
