Ankara : The Department of Industrial Engineering and the Graduate School of Engineering and Science of Bilkent Univ., 2013.Thesis (Master's) -- Bilkent University, 2013.Includes bibliographical references leaves 62-64.Electro discharge machining (EDM) is a manufacturing process where
material removal is realized through electrical discharges between two
conductive materials without applying any external forces. As a result,
high aspect ratio micro features on difficult-to-cut materials such as
tungsten carbide and polycrystalline diamond can be obtained. In this
study, influences of micro-EDM process parameters such as voltage,
capacitance, and rotational speed on material removal rate and surface
quality have been investigated using experimental techniques.
Experimental results have revealed that capacitance and voltage applied
during EDM process have significant effects on material removal rate and
surface roughness. Regression models have been calculated to represent
the relationships between process inputs and outputs which can be used to
calculate processing time and to predict surface finish. In addition, a
process planning software for wire-EDM process, which is capable of generating necessary tool paths during fabrication of micro tools, has been
developed. The software is also capable of producing the solid model of
the micro tools which can be utilized in computer aided engineering
applications.Özdemir, CemM.S
