Department Seminar by Erkan Günpınar

Using Quadrilateral Meshes in Reverse Engineering

Erkan Günpınar, The University of Tokyo

Date: Wednesday, July 03, 2013
Time: 10:00
Place: EA 409

Reverse Engineering (RE) aims to generate CAD model, a set of parametric surfaces, from a set of scanned points. Thanks to recent improvements, computational methods can now generate high quality semi-regular quadrilateral meshes which are suitable to be used in RE applications. In this talk, two techniques recently proposed by the speaker will be first explained in order to generate quadrilateral segments (from quadrilateral meshes) each of which are appropriate for parametric surface fitting. Both methods looks for an optimum segmentation of quadrilateral meshes (for RE) by utilizing optimization concepts. The last part of the talk covers an introduction of a problem from shipbuilding industry and a proposal to solve this problem using quadrilateral meshes.

About the Speaker:

Erkan Gunpinar is a PhD candidate at The University of Tokyo and will graduate in September 2013. His research interests are Reverse Engineering, Geometric Modeling, CAD/CAM, PDM and data exchange standards. From 2006 to 2010, Erkan worked for Samsung Heavy Industries as a research engineer in Mechatronics Center and had involved several projects to increase the speed and accuracy of manufacturing processes in shipbuilding. He earned his MSc in Mechanical Engineering from Korean Advanced Institute of Science and Technology (KAIST) with an e-manufacturing minor diploma in 2006 and his BSc in Mechanical Engineering from Middle East Technical University (METU) in 2003.
