The course content is designed to facilitate a working knowledge of the processes and steps on production of prototypes, from the inception of the concept, through modelling and all the way to the production of the physical model.Technologies Applied:
- CNC Milling Machine
- CAD Software
- STL Conversion or Stereolithography enabled software
- Manual design and process flows.
- Cobalt Steel Alloy (High Speed Steel/HSS) – for softer materials
- Tungsten Carbide in a lattice of Cobalt (Carbide) – for harder/more abrasive materials such as Titanium
- HSS end mills will wear out faster than Carbide ones – Carbide is a lot harder as a material.
- Carbide is more brittle than HSS and therefore requires more rigidity to avoid tool failure tool alignment is critical.
- Ability of carbide to withstand extreme heat allows for high cutting speeds.
- Up cut Spiral – tends to pull workpiece up. Preferred for cutting metal
- Down cut Spiral – Presses workpiece down. can affect chip ejection
- Straight Spiral – Ejects chips well.
- Flat end mill – Best for cutting flat areas with no scalloping
- Ball end mill – For non flat surfaces.
- Corner Radius end mill – Specialized for milling corners.
Software: Rhinoceros, Grasshoper
Challenges: Optimize the position and rotation of towers on the site
Optimize the position and rotation of the towers on the site by creating certain conditions. First, the towers are placed on the territory in a random position, then we give them parameters for placement and gives the program the command to start searching for all and the best possible options. The more conditions are set, the fewer options the program will have and the desired result will be closer to the goal.
Picture 1 – the initially given geometric data in the Rhinoceros, which are connected to the Grasshopper. Picture 2 – what the model looks like after attaching all the geometry to the grasshopper and adding the geometric parameters of our city – Moscow.
General composition of parameters. In this scale, the details of the code are not visible, so consider them in larger order.
1 part, responsible for attaching the geometry to the code, also breaks the points of the upper and lower surfaces, for the subsequent convenience.
Part 2 is responsible for the random distribution of towers on the territory in order to make the process as independent as possible from a person.
Part 3 was used to imitate the sun. An inclined curve was joined, divided into control points, from which the buildings were built. Later it was replaced by a real sun with orientation to geolocation.
Part 4 connects with ladybug the real position of the gps data to the city’s location, its weather and the trajectory of the sun throughout the year, with the help of which shadows are built for the model.
Parts 5 and 6 are responsible for setting the main tasks for optimization: that houses would not stand on top of each other, that would not go out of the plot, that would not stand in the shadows of each other, do not come closer than at the nth distance to each other etc. In addition, the strength of each condition can be specified separately, i. E. for example, the condition not to stand on each other is equal to 1, but not to stand in the shadow of a friend only 0.5.
The optimization process, when the program goes through all possible options and selects the ones most suitable for the required parameters.
All variants of the optimization process depending on the given conditions.
Post-production of optimization.
Software: SketchUp, 3dsmax, ArtCAM, Match3
Material: Plywood 10*10*1 sm
Challenges: Create a tile with your own drawing using cnc machine
The idea was to create a panel of Soviet hruschovka with its typical inhabitants.
DESIGN PROJECTIn the beginning, the base unit with clear dimensions in the sketchpUp was designed, exported to 3dsMax, where entourage and staffing – curtains, grandfather, cat and flower were added. Later, the model was exported to stl.
model from scetchUp
PREPARING WAYTo create a tile it was necessary to prepare a path for bits in the CNC machine. The path consists of two parts: draft and finish. Rough removes large masses, has a big step, but it works roughly. Pure has a smaller step on all axes, but takes much more time. When creating a path, you need to upload a file stl, specify the thickness of the material, and also the bit for the finishing and roughing path, then in the final path, you can choose the way to create the picture in the last step: one-way, two-way, radial and ect.
PROCESS OF MILLING
Neuro-technologieswithin the Technologies class we visited the amazing space opposite the LABA space, where scientists investigate the features of the human mind and consciousness by special devices, including software of mobile phones.
The picture demonstrates my level of mindfulness and concentration, which is evidently about 0. It’s pretty funny, because if you strain, the level grows noticeably and you can `blow up the barrel` (like in a computer game). Being a cheerful and tired nature, it was hard for me
Thus, wearables are being designed to improve not just physical health but mental well-being as well. Meditation apps in tandem with consumer EEGs like InteraXon’s Muse aim to help users build concentration and self-regulation skills. Even general-purpose fitness wearables are starting to include mental health and training applications. Jawbone (through its subsidiary BodyMedia) has secured patents that consider physiological and contextual factors. These are also systems that focus on improving learning and skill acquisition across the extended workforce through online interactive platforms and cognitive simulation models. Human capital-intensive organizations such as AT&T and Accenture, and start-ups such as Applied Cognitive Engineering, are developing multiple applications in the area, and securing relevant intellectual property rights.

Classes goalWe started to explore the possibilities of Rhino software and Grasshopper in order to create more optimized solutions – perform calculations of shadows, shapes for a particular place. The Evolutionary Computing term is widely known, more related to the programmers tool. The applications out there that apply evolutionary logic are either aimed at solving specific problems, or they are generic libraries that allow other programmers to piggyback along. The final goal was to optimize the Self-sufficient block design model. The various exercises were during the training period: Solar analysis: A large portion of a building’s performance has to do with how it behaves in relation to its environment, and one of the most important aspects of this environment is the sun. Thus, the way in which a building interacts with the sun, and what this interaction means for how the building performs and the way in which the building is experienced is often of primary concern for the architect, particularly in the early stages of massing and conceptual design. Thus, There are shadow study, which evaluates the extent to which a new building casts shadow on its surrounding area insolation analysis, which evaluates the degree to which a building’s surfaces (for example its facade) absorb the incoming thermal energy of the sun Both of these analyses are very useful in the schematic design process because they can have a big influence on the way the building’s form develops. Likewise, we can use these same metrics within the generative design process to automatically ‘evolve’ building forms that perform better in relation to the sun. Luckily, both of these analyses can also be quite easily done in Grasshopper. Let’s see how we can compute these measures by using a simple example of a building with a variable form and an adjacent park. Galapagos: Galapagos will provide a generic platform for the application of Evolutionary Algorithms to be used on a wide variety of problems by non-programmers. Galapagos is available in the current Grasshopper build. For more information on the concept behind Galapagos, please go the Evolutionary Principles applied to Problem Solving article.
