CyberCut: A Networked Manufacturing Service

ABSTRACT:
Getting leading-edge products to market faster than one's competition, is a key concern of the Nation's manufacturing enterprises. Correspondingly, many designers "out there on the Internet" quickly want "one-of-a-kind" mechanical prototypes or small batches of parts, to visualize and experiment with during the early conceptual stages of a new "high-tech" product.

Berkeley has established "an experimental fabrication testbed" for an Internet-accessible, computerized machining service called "CyberCut". Client-designers can now create mechanical components, beginning with a CAD system of their choice, and submit appropriate files to the server at Berkeley for process planning. "CyberCut" utilizes an existing open-architecture, computerized machine tool at Berkeley for fabrication. Rapid tool-path planning, novel fixturing techniques, and sensor-based precision machining techniques allow the original designer to take delivery of a component with a high-strength and tight-tolerance {e.g. +/- 0.002 inch (0.05mm)}. As the work proceeds, other services such as laser-cutting and precision machining will be included. "CyberCut" will first be used by University collaborators at Carnegie Mellon, Stanford and the MTAMRI at Illinois.

There are also some instances where the design has a complex shape that cannot be proto-typed by machining. We then need to evaluate other "Solid Free Form" technologies for the downstream prototype realization. To facilitate this step, we are developing a "Manufacturing Analysis Service" that evaluates the design for fabrication by Stereolithography or Selective Laser Sintering. We are using our industrial collaborators, Metalcast Engineering and Plynetics, for these extended services.

Graduate students at Berkeley are using the system today to design simple parts and get them machined within a day or two. We would be interested in your feedback on Design Tool which can be found at .

SPEAKER BIO:
At the University of California, Berkeley, Paul Wright is the holder of the A. Martin Berlin Chair in Mechanical Engineering, and is the Co-Chair of the Management of Technology Program, a collaboration with the Haas School of Business.

Previously, he was a Professor of Computer Science at the Courant Institute of Mathematical Sciences, New York University, and Director of their Robotics and Manufacturing Research Laboratory (1987-1991). Between 1979 and 1987 he was a Professor of Mechanical Engineering and of the Robotics Institute at Carnegie-Mellon University. He has also been a Research Associate in Physics at the University of Cambridge, England (1978), a Senior Lecturer in the Department of Mechanical Engineering at the University of Auckland (1975-1978), and a consulting engineer for an industrial development laboratory in New Zealand (1972-1975).

He was born in London and obtained his degrees at the University of Birmingham, England. He has published over 200 papers and reports that span the areas of: metal processing especially machining; robotics and its applications in flexible manufacturing systems; the development of expert systems for manufacturing; controllers for open architecture manufacturing; rapid prototyping; and Internet-based CAD/CAM. In this latter area, the ongoing project at Berkeley is entitled "CyberCut: A Networked Manufacturing Service". This is funded by NSF, Visteon, Sun Microsystems and Boeing. He is also a consultant on these topics for a number of industrial corporations, national laboratories and business planning organizations. His book "Manufacturing Intelligence" published in 1988 with David Bourne, was one of the pioneering contributions that combined manufacturing processes with artificial intelligence. Other books in-press are "Metal Cutting" and "Technology and Management: Bridging Two Cultures to Create Leading Edge Products"
