05 > computer controlled machining
i decided to start the building the
structure of the dog house this week so I can experiment
with it as a small scale structure to test various
architectural features in future weeks. I was interested in
a flat pack design that could be easily assembled and
disassembled and could easily change configuration depending
on the day. I explored origami and deployable structures
that employ folding to convert a 2d design into a 3d
enclosing volume. The paper model illustrates my intentions
however I encountered issues tying to figure out how to
scale this from a 2d sheet material to the thick plywood.
Living joints by kerfing the plywood would
prove unfeasible for the sharp angles required, and in the
interest of time this week I had to change my plan. Instead
I used this week to build a simple frame that I could use in
addition to some scissor mechanisms and possibly a thin
rigid folding composite skin to create the exploding volume.
When laying out the pieces to be cut, with the first draft
ending up requiring 3 sheets of plywood while wasting alot
of material with the voids. Taking into consideration that
and some other advice from Chris Dewart at the N51 shops on
how to maximize results - such as limiting the length of
tabs to avoid them breaking, keeping 3/8 inch space between
pieces. I made some amendments to the design while
transferring it from Rhino to Grasshopper: increased the
width from 5cm-8cm and separated the bottom member - since
it wasnt integral for the design so that the pieces could be
nested and fit onto a single 4ft x 8ft sheet.
