VFab Digital Fabrication
INVESTIGATORS: A. Scott Howe (PI), Lynn Conway (Co-I), Donald Geister (Co-I). Advisors: James Turner, Harold Borkin, Michael Parsons, Lynn Conway.
FUNDING: Supported by Kajima Corporation, Tokyo, Japan as part of doctoral research.
PERIOD: 1997.
ABSTRACT: This project creates a web-based link between students / designers / small companies and Numerical Control (NC) shops and manufacturing facilities via the Internet. Using a web page maintained by an independent entity, designers can submit designs using a custom-made java web browser plugin application which funnels DXF data to special NC woodworking and metalworking shops. The shops can quickly process the requests, and send the finished pieces directly to the designer.
During 1997 multiple files were produced and sent anonimously by various art students through the VFab program.

1) Solid object is modeled on a solid modeling program.
2) The solid object is unfolded using unfold algorithms, and output a DXF file representing the cut and fold lines. 3) The designer uses the web-based browser plugin to submit the file, which automatically directs it to a manufacturer. |
 |
4) The manufacturer obtains the DXF file from the Internet in the form of an email attachment or ftp upload.
5) The file is opened and converted to machine vector code. 6) Machine vector code runs the laser cutter to cut the piece out of sheet metal or other sheet stock. |
 |
7) The cut fabrication is ready to be folded.
8) Piece can be shipped out by the manufacturer, either folded or unfolded as required. |
