Reliable scheduling in cutting conditions is very important in machining processes, and this requires thorough understanding of the physical behaviors of the machining process, which cannot be achieved without understanding the underlying mechanism of the processes. The book describes the mechanics and dynamics together with the clamping principles in milling processes, and can be used as a guideline for graduate students and research engineers who wish to be effective manufacture engineers and researchers. Many books have focused on common principles, which are suitable for general machining processes, e.g., milling, turning and drilling, etc. This book specifically aims at exploring the mechanics and dynamics of milling processes. Original theoretical derivations and new observations on static cutting force models, dynamic stability models and clamping principles associated with milling processes are classified and detailed. The book is indented as a text for graduate students and machining engineers who wish to intensively learn milling mechanism and machine tool vibration.

"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.

This paper presents the suitable depth of cut, spindle speed and feed rate that will be chosen during machining. If thus parameters are not considered, this can provoke abnormal tool behavior such as chatter. Chatter will limit the tool life which only can be use for just a few times. To predict the chatter occurs, the parameters will be use are spindle speed, depth of cut and feed rate. CNC machine will be use. This process will base on dynamic cutting force model for ball end milling. The selections of cutting tool are depends on the process that will done where the chatter can be observed during this machining process. Cold work tool steel (AISI-D2) chosen as a material and its parameter is 100x100x25 mm. Cutter used was high speed steel 2 flute ball nose. Force dynamometer will be use to measure force and 27 tests will be done to observe the chatter occur. Analysis done by referring the result that measured by force dynamometer. The chatter in ball end milling can be detected from the calculated cutting forces and their frequency spectra. A comparison of the predicted and measured cutting forces demonstrated that the proposed method provides accurate results.

"This research presents the results of the development of a mechanistic cutting force prediction model for the wavy-edge bull-nose helical endmill (WEBNHE). The mechanistic model was developed to predict cutting force components and the resultant cutting force in high-speed end-milling of Inconel 718 under two cooling strategies: emulsion and Minimum Quantity Lubrication (MQL). The effects of the cooling strategies are incorporated into the mechanistic model through six cutting force coefficients (K[sub tc] ,K[sub rc] ,K[sub ac]), and edge force coefficients (K[sub te], K[sub re], K[sub ae]), which have been experimentally identified in a separate research. The mechanistic model was validated by conducting end-milling experiments on Inconel 718 using a WEBNHE of 1.25'' diameter under emulsion and MQL cooling strategies. In addition to cutting forces prediction, the mechanistic cutting force prediction model is used to investigate the effects of the cooling strategy, and the effects of the geometric parameters of the WEBNHE on the predicted cutting force components and the resultant cutting force. The geometric parameters investigated in this research were: wave magnitude, wave length, axial shift, and the helix angle. The cutting force components and the resultant cutting force predicted by this mechanistic cutting force model under the two cooling strategies were in good agreement with the experimental results. Additionally, the results show that an increase in the depth of cut under MQL generates less cutting force than the same increase under emulsion. Moreover, all predicted cutting force components increase when the magnitude of the WEBNHE increases, whereas they decrease when the wave length, axial shift, and the helix angle increase"--Abstract, page iv.
