"This thesis presents the results of the investigations of mechanistic modeling and simulation of cutting forces in high speed end milling of titanium alloy, Ti-6Al-4V, and the determination of specific cutting and edge force coefficients for carbide bull-nose helical end-mill. A generalized mathematical model representing the outer geometry of an end-mill and the cutter edge geometry is presented. Mechanistic cutting force models have been developed for a general helical end-mill and modeled specifically for a bullnose helical end-mill. A MATLAB code for the mechanistic cutting force models have been developed for the simulation of cutting force components in end milling and for the determination of specific cutting and edge force coefficients for any workpiece-tool material pair. Specific cutting and edge force coefficients are obtained for carbide bullnose helical end-mill - titanium alloy workpiece material pair at 10% radial immersion up-milling experiments. The effects of machining parameters: feed per tooth, helix angle, axial depth of cut, corner radius, number of cutter flutes, and spindle speed on cutting forces were investigated. End milling experiments were conducted on titanium alloy, Ti-6Al-4V, using a 0.5 inch (12.7 mm) diameter carbide bull-nose helical end-mill to verify the models. Predicted cutting force components (F[subscript x], F[subscript y], and F[subscript z]) obtained by the mechanistic cutting force models were compared with measured experimental values, and also with predicted and measured values from published literature. The results were in good agreement in both cases. This method for the determination of specific force coefficients and predicting cutting forces for titanium alloys can easily be extended to other metal alloys such as Hastelloy, Inconel, and niobium alloys"--Abstract, leaf iv.

The development of miniaturized technologies has become a global phenomenon that continues to make an impact across a broad range of applications that encompasses many diverse fields and industries including telecommunications, portable consumer electronics, defense, and biomedical. Subsequently this trend has caused more and more interest in the issues involved in the design, development, operation and analysis of equipment and processes for manufacturing micro components. One technology used to create these miniaturized components is micro end milling. The cutting forces of the micro end milling process provide vital information for the design, modeling, and control of the machining process. To gain an understanding of forces in micro end milling operations, a model of average chip thickness is derived and the differences between conventional end milling and micro end milling are enumerated. From the experimental results, empirical models for specific cutting constants were derived and compared the generally accepted forms for conventional end milling operations. These models provide a tool for the estimation of cutting forces in micro end milling.

"This thesis presents the results of experimental investigations of the mechanistic identification of specific force coefficients for uncoated bull-nose and uncoated wavy-edge/bull-nose helical endmilling of Inconel 718 under emulsion, minimum quantity lubrication (MQL), cryogenic (LN2), and combined (MQL + LN2) cooling. Several slot milling tests were conducted on Inconel 718 workpiece block with depth of cut 1.25 mm. The cutting parameters were varied as: spindle speed, n = 250 and 750 rev/min, feedrate, f = 25-75 mm/min by using uncoated carbide bull-nose helical endmill. Also 24 peripheral milling tests were conducted on Inconel 718 workpiece block with axial depth of cut 18.75 mm and radial depth of cut 1.75 mm. The cutting parameters were varied as: spindle speed, n = 62 and 93 rev/min, feedrate, f = 27.9-55.8 mm/min by using uncoated cobalt wavy-edge/bull-nose helical endmill. Cutting force components and specific force coefficients have been experimentally determined to compare the effects of different cooling methods. Eventually, six specific cutting and edge force coefficients (Ktc, Krc, Kac, Kte, Kre, Kae) have been determined for uncoated bull- nose and uncoated wavy-edge/bull-nose helical endmilling of Inconel 718 workpiece under the four cooling methods (Emulsion, MQL, LN2, and combined (MQL+LN2)), thus a new database that hitherto does not exist in published literature has been created to be used for accurate prediction of cutting forces under typical industrial machining conditions"--Abstract, page iv.

Tribology of Metal Cutting deals with the emerging field of studies known as Metal Cutting Tribology. Tribology is defined as the science and technology of interactive surfaces moving relative each other. It concentrates on contact physics and mechanics of moving interfaces that generally involve energy dissipation. This book summarizes the available information on metal cutting tribology with a critical review of work done in the past. The book covers the complete system of metal cutting testing. In particular, it presents, explains and exemplifies a breakthrough concept of the physical resource of the cutting tool. It also describes the cutting system physical efficiency and its practical assessment via analysis of the energy partition in the cutting system. Specialists in the field of metal cutting will find information on how to apply the major principles of metal cutting tribology, or, in other words, how to make the metal cutting tribology to be useful at various levels of applications. The book discusses other novel concepts and principles in the tribology of metal cutting such as the energy partition in the cutting system; versatile metrics of cutting tool wear; optimal cutting temperature and its use in the optimization of the cutting process; the physical concept of cutting tool resource; and embrittlement action. This book is intended for a broad range of readers such as metal cutting tool, cutting insert, and process designers; manufacturing engineers involved in continuous process improvement; research workers who are active or intend to become active in the field; and senior undergraduate and graduate students of manufacturing. · Introduces the cutting system physical efficiency and its practical assessment via analysis of the energy partition in the cutting system.· Presents, explains and exemplifies a breakthrough concept of the physical resource of the cutting tool.· Covers the complete system of metal cutting testing.
