I used screen shots from this software along with a reference image of a Stretch Surfboard model that I use to own to recreate the desired shape with T-Splines in Rhino. I decided upon a concave bottom, which acts to contain water flow through the length of the board, creating greater pressure through the fins which adds lift and minimizes drag. This software is used by shapers to automate the process of cnc produced foam blanks, but I was most interested in the ability to quickly explore the bottom contour profiles. Although I had previously generated a 3D file, I went through the process again, this time using a software specifically built for board design called "AKU Shaper". My "Make Something Big" project continues the path of surfboard design exploration and I chose to build a hollow wooden frame surfboard. At first the number of setup steps seems overwhelming, but after going through the process once or twice, it becomes very easy. The large ShopBot can handle stock material up to 4'x 8' while the smaller desktop unit can mill sheets that are up to 24" x 18". While the range of this equipment varies from several hundred to over a million dollars, the Harvard section has access to two ShopBot milling machines. This week we were introduced to the concepts, techniques and machinery within the realm of computer-controlled machining.
