Abstract
The talk will present recent work by the speaker’s group on fundamental studies of the diamond wire sawing process used to slice single and multi-crystalline silicon wafers for solar cell applications. Specifically, the talk will focus on the role of abrasive shapes, microstructural defects, and the role of cutting fluid on the mode of material removal and on the surface and subsurface damage produced in diamond scribing studies that simulate the grit-material interaction in diamond wire sawing. The talk will conclude with remarks on possible areas of future work.
Dr. Shreyes N. Melkote holds the Morris M. Bryan Professorship for Advanced Manufacturing Systems in the George W. Woodruff School of Mechanical Engineering at Georgia Tech.He also serves as Associate Director of the Georgia Tech Manufacturing Institute. From August 2015 - July 2016, he served as an ASME Foundation Swanson Fellow at the Interagency Advanced Manufacturing National Program Office at the National Institute of Standards and Technology (NIST) where he contributed to various policy aspects of the National Network for Manufacturing Innovation Program (now Manufacturing USA). Dr. Melkote’s current research interests are in materials and modeling aspects of precision machining, novel surface enhancement methods, and robotic machining. His research in these areas is actively supported by industry and government sponsors. He is a former President of NAMRI/SME, and a Fellow of the ASME and the SME, and an Associate Member of the CIRP.
