In many experiments, some of the factors exist only within the level of another factor. Such factors are often called nested factors. A factor within which other factors are nested is called a branching factor. For example, suppose we want to experiment with two processing methods. The factors involved in these two methods can be different. Thus, in this(More)
ACKNOWLEDGEMENTS I would like to extend thanks to all of the people who made this thesis a reality. I could never have done this alone. I would especially like to acknowledge my thesis advisor, Dr. Steven Danyluk, for his support of this research as well as his patience throughout this process and the willingness to allow me the freedom to find my own(More)
This project aims to provide fundamental understanding of the wire sawing process of silicon wafers. The traditional multi-wire slurry sawing technique (MWSS) and the fixed abrasive diamond wire sawing (DWS) technique as a new promising alternative are compared. Fundamental experimental and modeling studies of single grit diamond scribing on silicon are(More)
An experimental study of the effect of fixture-workpiece conformability on system static stability is presented. Conformability is defined as the geometric similarity between the workpiece and the smallest polyhedron fit over all fixture-workpiece contacts. Two metrics, C 1 and C 2 , are introduced to quantify global and local conformability, respectively.(More)
Dynamic instability in the form of chatter is a highly undesirable phenomenon that occurs during machining, resulting in poor surface finish and reduced tool life. Though analytical models exist for identifying conditions that avoid chatter, they do not account for process uncertainties or they require extensive cutting tests. Therefore, an on-line chatter(More)
