2.753F Furniture Design
Summary: Students will learn the experience of product design by designing, building, and refining a piece of original furniture from scratch. Basic design principles such as ergonomics, mechanical robustness, and manufacturability will be taught in conjunction with traditional drawing skills and computer‐aided drafting techniques. Building techniques will be taught in the mockup and prototyping stages, beginning with handheld layout and cutting tools, progressing to machine‐powered hand tools and finally computer‐controlled fabricators, including 3D printing, waterjet and CNC mill. The final project will be a finished, finalized version of their furniture piece.

Week
SCHEDULE Lecture
1a
Introduction ‐ Course Overview. Design principles 1 fulfilling a need or desire improving or replacing an existing product inventing a product for a new activity function(s) appeal/style
1b
Why furniture? Furniture specifics.
tables, chairs, cabinets, beds novel categories of furniture? new inventions?

Assignments
SAFETY SAFETY SAFETY wear safe clothing and protection have a clear mind using resources responsibly measurement and marking square protractor ruler + tape measure calipers understanding materials metal
Acquire the following: OMAX Autodesk Inventor drawing paper (no lines, etc) graph paper mechanical pencil + eraser drawing pencils
plastics wood
paper + composites
Do a little research. Take a trip on your own time to the Design Within Reach store and neighboring furniture stores in Central Square. Take note of your favorite furniture piece(s). Why do you like them? Start thinking of some interesting, novel, and/or improved furniture ideas. Draw a rough sketch of your idea(s).
Choose one of your ideas you would like to pursue as a final project. 2a
Drawing orthogonal views isometric three‐view perspective views 1, 2, and 3, point perspective how to fake it

Draw: cube, cone, cylinder, in 3 views. GRAPH PAPER IS YOUR FRIEND!
hand tools knife, chisel, file, saw
Draw: a [teapot] in 5 views on graph paper. (top, front, rear, bottom, side)
primitives cube, cylinder, sphere, cone using primitives to form more complex shapes proportion portraying light and shadow: shading and contrast Brief History of modern furniture (Hayami) Prototyping 1 brainstorming: sketches + visual mockups
critical components (the core)
ok to have bad ideas in search for a good one selecting one or several ideas to prototype
Draw: a shaded cube, cylinder, cone, and sphere from life. Draw a shaded teapot in perspective view.
hand‐operated machine tools saw, drill, mill, lathe
Revisit the furniture design you came up with earlier, draw the 6 views and a shaded perspective view of it.
joiner, planer, router power sanders joinery POSTER PRESENTATIONS 1/4 scale furniture mockup: Using the layout tools, draw the 4 views of your furniture mockup and cut the shape out using the bandsaw. Make a pencil line drawing (no shading) of an object which you want to model in the computer. The model must have the following: An extruded solid An extruded cut A revolved solid

CAD lessons continued: Use OMAX to create precise 2D drawings use Inventor to create a part
A revolved cut Fillets or Chamfers
Dimension your object. Create a shaded perspective view of the object.
CAD:
Computer‐Aided Machining (CAM) Waterjet: Path setup (in OMAX Layout)
Using your pencil drawings, Create a solid model of the individual parts of your design. Create an assembly and drawings of each part. Create full‐scale mockup of your project using bandsaw, router, drill, etc. Finish the mockup of your product. At this point, how would you modify it?
3D Printer: Place and slice a model (in Repetier ‐ Host) demonstration prototypes (theme and) variations CNC Router/Mill: Programming a toolpath (in MasterCAM) MOCKUP + IDEA PRESENTATION
2.5D ‐ contour, face, pocket, drill
Critiques
using the same dimension where similar
use pre‐existing components where possible use the same component where possible
