Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

The report contains a program of research which is directed at the problem of determining the dynamic stability of machine tool-metal cutting systems. Such a study will provide machine tool manufacturers with the necessary analytical methods tests and specification techniques to determine a vibration free cutting for machine tools. The special advantage of the system analysis by means of stochastic signals is the natural kind of stressing during the record of signals for the dynamic compliance test. (Author).

Focussing on occurrences of unstable vibrations, or Chatter, in machine tools, this book gives important insights into how to eliminate chatter with associated improvements in product quality, surface finish and tool wear. Covering a wide range of machining processes, including turning, drilling, milling and grinding, the author uses his research expertise and practical knowledge of vibration problems to provide solutions supported by experimental evidence of their effectiveness. In addition, this book contains links to supplementary animation programs that help readers to visualise the ideas detailed in the text. Advancing knowledge in chatter avoidance and suggesting areas for new innovations, Chatter and Machine Tools serves as a handbook for those desiring to achieve significant reductions in noise, longer tool and grinding wheel life and improved product finish.

A theory is formulated using a feedback loop to represent the chatter mechanism. This theory permits the calculation of borderlines of stability for a machine tool system having a structure with n-degrees of freedom. A cutting stiffness table is presented in which data from the literature are given in a form of cutting stiffness per unit width of cut for various materials. The dynamic behavior of the cutting process is explored in depth yielding an understanding and qualitative description of observed dynamic behavior. The theory of transfer functions of structures has been derived enabling the prediction of structure dynamics of simple continuous systems. Measured and computed stability diagrams are presented demonstrating the validity of the developed stability theory. From the research program initial chatter specifications have been formulated. Such a specification, if established, would define the ratio of minimum directional dynamic stiffness of the structure over the rated horsepower of the machine tool. (Author).
