Virtual Repair: Geometric Reconstruction for Remanufacturing Gas Turbine Blades

by preciseadmin | Aug 14, 2011 | 2011, Cecil Piya, HUMAN SHAPE INTERACTION, Karthik Ramani, Publications, Shape Understanding

Abstract: The usage of Direct Metal Deposition (DMD) technology for repairing defective voids in high-value metallic components is time consuming, since traditional geometric reconstruction methods are not seamlessly connected to the DMD process. Here, we consider the...

Towards Enabling Visual Design Exploration Involving Multiple Abstractions of Design Descriptions
