Assignment: to do the press-fit smth

Software: Rhino 5, LaserWorks

Equipment: Laser Cutting Machine

Material: 4mm plywood

I started with an idea to make something simple and at the same time functional. Thus, I decided to make an iPhone stand, which could be useful on daily basis. 

I sketched a laconic design consisted of 3 pieces. The angle of the main surface provides convenient usage of the device. It is easier to type, scroll and swipe through content and, last but not least, enables to unlock your phone through face ID without picking it up.

Further, I made a precise drawing of the stand in Rhino 5, which is compatible with a software for laser cutting machine (LaserWorks).

After cutting out the whole thing and trying to assemble it, I found out that press-fit joints are not tight. Apparently, this happened because of the machine’s possible errors. Gaps should have been smaller, while reply part, conversely, wider. Because I did them equal, I had to use a glue to fix this mistake.

Eventually, I managed to get it all together and there it is in use!

Assignment

To construct the highest tower possible using press-fit technology with following limitations:

  • Only three types of elements are available, each not bigger than 150mm x 150mm.
  • The size of the plywood sheet available for cutting is 900mm x 600mm.

Software / Materials

  • AutoCAD
  • Rhino 6
  • Laser Works
  • Plywood

Machine

  • Laser cutter

Sketching & Drawing

To develop a design we started by sketching our ideas, at first each member of the team proposed a design. From the three of them we choose the one we thought it was going to be the tallest and the most stable.

After having the design on paper we took it to a drawing software in order to make the design more precise.

Cutting

During the production of pieces we faced a problem:

It took us some time to adjust the laser itself for a precise cut. We changed the speed and the power of the machine a few times, but still, we weren’t satisfied with the result.  Only after adjusting the focus of the laser we managed to get a fine incision without burning plywood.

Construction

For joints we left the space of 3mm, while the width of the material was 3,9 mm. This made or joints quite tight, but we had to widen some gaps with a rasp and attach them with a help of a small hammer.

We managed to make our tower as high as the ceiling height in our lab. But, unfortunately, it was standing only because the construction abutted the ceiling.

Final Result

That is why the design of the tower deviated from the original plan during construction.

In the basement we changed 45-degree trotters to 90-degree and connected them at the bottom. This solution gave our tower more height in the basement part and, of course, more stability. In the upper part we managed to balance it with a square element. It was still leaning to the side but stood properly.

At the end, even though it was not as high as the first variant, we managed to get more or less stable construction.

Class – technology, laser cutting

SOFTWARE | MATERIALS
– AutoCAD
– 4 mm birch plywood

MACHINE
Laser cutting machine, Raylogic AS-1290C

ASSIGNMENT
Prototype small individual project by brainstorming, drawing, and laser cutting.

LIMITATIONS
– 10x10x10 cm space
– Press fit
– Not a toy

GOAL
The main objective of the task was to learn how to come up with good ideas, how to develop it, how to use graphic design programs, and, eventually, how to use laser cutting machine.

DESIGN
I wanted to create something light, stylish and mindful. After brainstorming the possibilities I understood that wooden sticks can be a good element of the work – they are really functional and strong. Plus, you can map a lot of them even in the limited space. The idea of bench was simple and smart, because benches are common elements of the city landscape. 

First stage was sketching:

Processed with VSCO with h3 preset

Then I tried to draw elements, which later would be created in graphic designer:

As my graphic skills left much to be desired, I turned to classmates who taught me how to use AutoCAD. Eventually I got this design:

In order to make the connection of sticks tighter, i decided to reduce holes by 0.1 mm from each side.

Finished dwg-file was opened with software and send to laser printing.

Produced elements were easy to assemble and the connection was so tight, that no glue needed.

MATERIAL: Plywood 100*100*4 mm

MACHINE: Laser Cutting Machine Raylogic AS-1290C

CHALLENGES: Create something press-fit


TASK / PREPARATION

The task sounded quite simple: create something pressfit using plywood. This task had a goal to develop our skills in Rhino and Laser cutting.

As far as we had only one material and small size of this material, I decided to make a two-sided keychain to make people on the streets happier. I had an idea to write something inspirng, which ended in “Hey, You! Smile ;)”.


DESIGN PROCESS

The sketch of the key chain came into my mind in the metro, so I decided not to waste my time and draw it in Rhino.


LASER CUTTING

After saving my file in .dxf format I passed to the computer, which is connected to the Machine. I open the file with “File – Import” and placed it on the “surface” of the Laser Cutter.

I had to make two layers:

  • general layer of cutting (Speed 9mm/s; Power 95.0);
  • layer for “printing” (Speed 200 mm/s; Power 30.0).

First layer cutted the key chain itself, second one was slightly burning the plywood to “print” the letters.

“Printing by Laser cutting machine”

Because of the problems with the machine, I had to cut it twice. Because of that, the size of connecting sticks was smaller than the holes. I had to use glue to connect it.


RESULTS & REFLECTION

As a result of the work, I created a key chain, which is actually is not a press-fit thing. The idea itself was not a press-fit from the start.

Laser cutting is a simple and cheap (materials) technology to create prototypes.

The task allowed me to understand the main principles of working with Rhino and the laser cutting technology itself.

As an overall result, I can now give people another reason to smile, when they see my key chain on the backpack.


GRASHOOPER A tool for generative modeling that allows you to create parametric models, parametric architecture in Rhinoceros 3D environment

Interface plug-in
The process of modeling in Grasshopper is the creation of an algorithm. At Grasshopper the interface, it means that we write the script text, and we connect years and we set some options.
The algorithm consists of the initial data or parameters and the sequence of actions with them. As a result, geometry and related information (volumes, areas, markings, sizes) are generated.
With the help of noses and parameters, geometry can be changed, you need to change the value of one year and make a shift, and all geometry will be rebuilt.
Thus, in Grasshopper we create not only a model, but the logic of its behavior. Once you have created a script, you can reuse it and edit it further.

In this model, the task was to build a geometry dependent on the point of attraction. Attractors in a rectangular node

You can add an attractor to a suitable site in three ways: drag the element onto the agent chart or use the drawing mode, in which case the graphics editor will select the shapes suitable for setting the attractor; or select the node and add the attractors by clicking the Attractors button … in the node properties.
The created geometry is easily changed by changing the parameters of the code components.

Introduction:

This is about what it takes to get things done. Every project has a life cycle and the hardest of all the stages is the materialization – the manifestation of the physical project. This is the true challenge and test of a makers worth. Working on the realization of great ideas requires tools and manpower. In this instance both were equal to the task of realizing Elena and Ivan Mitrofanova’s project “Green Spark”

Introduction:

BCI feedback induces cortical plasticity, a basis for prompting behavioral changes, improving cognitive performance, ethics aside – neuromarketing … and on the surface test your concentration skills through gamification. In about a decade or so, interfaces like mindwave could be the obsolete versions of advanced wetware.

Test of user interface – Mindwave

The market for neural interfaces is relatively young and the relevant technologies are still growing. At the moment these user interfaces look more like prototypes  rather than the final product. It is envisaged that the technologies would evolve into more user friendly interfaces which would seamlessly interface man with virtually any networked platform. The potential for these items is colossal, however for now we have to be satisfied with the clumsy software on the phone which cannot really performs quite as seamlessly as it should.

Challenges: Create a tile with your own drawing using cnc machine

IDEA

 

The idea was to create a panel of Soviet hruschovka with its typical inhabitants.

 

DESIGN PROJECT

In 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.

PREPARING WAY

To 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.

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.
