ATTENTION: PHOTOS OF THE PROJECT WILL BE ADDED ON 15.07 DUE TO absence of laptop with all the working materials on all the projects

Class: Technology.

Software: Autocad, Rhino.

Material: Styrofoam 150*150*60 mm.

Task: Create the figure by using plywood ( or Styrofoam in my case) which is possible to cut with CNC machine.

Drawing the project

Our first task in the 2nd semester in Shukhov Lab was to create a 3-D object in cad software in order to cut it out on the CNC-machine afterwards.

After taking some time to find an interesting project I assumed it would be nice to take something big in real life and to scale it down as a CNC-project. Thus, my working on the mini-golf field started.

I was inspired by the photo of golf-club, located in Rostov region called Golf Country Club “DON”

‘place for photo’

I started to work in Autocad, proceeding later in Rhino software. The problem was to make the surface smooth without using Metaballs plugin. After several hours of ideas and the same amount of time for creation I managed to get something looking like that:

‘place for photo’

Actually, the edges appear to be not that smooth as I planned them to be, but still it looks original and worth trying to cut the golf field out. We decided with the tutor Ivan it would be better to try this project on the styrofoam form not to spoil the wooden sample just in case.

Cutting time

The process of cutting appeared to be something interesting because it was unusual to me to visualize the accurate work on tiny object by the big machine, capable to cut almost anything from the piece of square. It is important to fix the sample of material in order not to allow it change its position while the special drill head does its work.

The result

After approximately 25 min we managed to get the result of the whole concept looking this way:

I guess, from the wooden sample it would look much nicer, but we get what we get, next time maybe we’ll try something more worth to spoil the real wooden sample:)

With this project I got the idea how to cut out any 3-D object you want to transfer it from the virtual reality to real life.

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 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” Tools:

Class: Technology, CNC Milling
Software: SketchUp, 3dsmax, ArtCAM, Match3
Material: Plywood 10*10*1 sm
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.

RESULT

         

TOWER – GNM

Assignment Parameters:
The assignment was to construct a tower using press fit laser cut modular pieces with a dimensional 
limit of 150mm on the length. 

Materials:
Modular patterns were restricted to 3 patterns or modular units.
Laser Cut plywood

Modular Units for Tower Structure

Pre-Design - Conceptual approach:
The concept was based on attainment of the maximum height without compromising the structural 
integrity of the tower frame. with these two parameters as the basis, it was evident that 
additional stability could be attained by the use of a cross-pattern of "beam" structures. 
Horizontal elements were left out. 

Iterations and Re-Design:
In line with the initial concept of simplicity, there were few iterations between the initial 
design and the final version.

Assembly of Tower

Fully Assembled Tower

Troubleshooting:
The initial design had stability issues due to the initial proposal of framing the beams using 
continuous interlocking. This made the initial design heavy. Whereas the interlocking pattern 
was maintained for the base in order to keep the structure stable, the interlocks were discarded 
at the subsequent upper levels, making the structure lighter and allowing for attainment of 
increase height.

Cutting & Assembly:
Cutting out of the modular units was done using a laser cutting machine.
The cutting process took about 45 min.

The Team

Credits:
Whereas the final product was a product of active team work on the part of all team members, 
the cutting work was conducted under the guidance of the course supervisor Ivan Mitrofanov 
since at the time non of the team members could conduct the cutting works independently.
