Direct Design and Manufacturing from Acquired Point Cloud Data

 Xiaoping Qian
Illinois Institute of Technology
Chicago, IL 

March 24th, 2008 (Wednesday)
(Please note new Date, this meeting was rescheduled from the 12th)

Rapid advancement of 3D sensing techniques has lead to dense and accurate point cloud to be readily available. In this talk, I will present two recent technological advancements that enable product design and manufacturing directly from acquired point cloud data.

The first one is a new approach that enables the integration of an area laser scanner and a point sensor for rapid and accurate 3D shape acquisition and modeling. The uniqueness of this approach lies in the symbiotic combination of sensing and modeling: sensor data are dynamically incorporated into the shape model, which in turn dynamically steers further sensing. The second one is a new approach that enables direct shape design and manufacturing from acquired point cloud data without the laborious and error-prone reverse engineering process. The novelty of this approach is the use of a novel point-set surface in CAD/CAM applications.

Several examples on direct design and manufacturing from point cloud data, including rapid product geometric design, NC machining, rapid prototyping and metrology, will be presented.

Bio:

Xiaoping Qian is currently an Assistant Professor in the Department of Mechanical, Materials and Aerospace Engineering at the Illinois Institute of Technology. Prior to his current position, he worked as a research scientist at General Electric Global Research Center, Schenectady, NY from 2001 through 2004. He obtained his Ph.D. in Mechanical Engineering from the University of Michigan.

His general research interests are in the area of information science-driven product design and manufacturing. His current research activities, supported in part by NSF, AFOSR, SME, and General Electric include 1) point-based computational techniques that can support direct design and manufacturing from 3D sensing, and 2) tip-specimen shape interaction modeling in atomic force microscopy for nano-manufacturing and nano-metrology.
