GROUP ASSIGNMENT

For our group assignment we went thorugh cnc and woodwork training at the archshop down in N-51. Chris started with a logistics brakedown for the coming week, tailored for safety and high-traffic high-traffic management at the shop.

Next, we went into the file prep for the cnc-milling process. Following Jen's template, each student would have to submit 2d rhino files with specific layers for specific cnc-milling paths, and, with the help of a shop manager or TA, create the mastercam file.

Then, we reviewed the actual properties of OBS, which would inform our design and its structural logic. Subsequently, Chris showed us typical cutting and sanding procedures for this type of project, emphasizing on safety and cleaning protocols.

Finally, once our material batch had arrived, we measured it and cnc-milled a joint test-cut. We determined that our 4.33inch boards would connect best with 0.488inch wide, 2-inch deep tenon hole. Thanks to Chris, Jen, and Diana for all your help!

CNC
MILLING

I decided to build a modular self-supporting system with 2 component types that could be assembled into diverse structures. Instead of cutting my whole board from the start, I fisrt cut a sample connection test that proved succesful.

With the test complete, I proceeded to cut the rest of my board, which took about half an hour. The cut did not perfectly go all the way through, but with a couple of strong taps, the pieces came out.

SANDING

As my cut had rough, spiky edges, they had to go through a sanding process. The best tool to get me started was the fixed table drill sander, which is quite dangerous for small pieces, but would work perfectly for my triangular components.

Pressing the components downwards, without gloves, and moving them with the rotation of the bit, I quickly sanded the outer and then inner edges of my larger components.

Next, to clean out the edges of the connection holes and for all the edges of my smaller components, I used a couple of hand files. Once I completed this process, my components were ready for assembly.

PROCESS

In the end, my self-supporting modular 2-component system turned out to be succesful. It is lightweight enough that it can easily be handled manually, and assembled into diverse structures and patterns.
