Abstract: Tool selection is one of the most significant process considerations when deciding how a machined product will be manufactured. The tool selection activity is rooted in feature geometry but it also has a direct impact on machinability and machine tool performance. This paper presents a computer-based intelligent system for the automatic selection of cutting processes and tools. The main objective of the research work was to develop a procedure for the selection of cutting tools and cutting parameters. This will help the designers and manufacturing planners to select an optimal set of cutting tools and cutting conditions for different material properties and to give users alternatives on how to reduce cost and time.

Abstract: In micro milling, cutting parameters such as feed per tooth and cutting speed are found to have significant influence on cutting forces and surface quality. To address these issues, an experimental study of micro milling with three types of metal material (steel, brass and aluminium alloy) is conducted. The experiment setup and cutting conditions are described; the experiment results are presented with a discussion of the influence of various cutting parameters such as feed per tooth and tool diameter. These results are used to provide strategies to optimise cutting parameters and achieve better surface quality with the concern of tool diameter and material hardness when micro milling selected materials.

Abstract: The milling experiments of the annealed T10A steel were carried out in the various cutting conditions using the coated cemented carbide tool. The cutting parameters were designed by the multi-factor orthogonal experiment method, and the effects of cutting speed, feed, axial depth of cut and radial depth of cut on the cutting force and tool wear were investigated. The tool wear mechanisms were also discussed. Adhesion, abrasion, diffusion and oxidation were the main tool wear mechanisms. According to these investigations, the optimizing cutting parameter was recommended.

Abstract: In the study of high speed cutting technology of complex parts, cutting methods and techniques must be closely combined with the selection of geometric parameters of cutting tool materials and cutting tool integrated. Numerical control machine tools and cutting tools without good guidance technology, cannot give full play to the advantages of NC machining. Based on this, this article mainly aimed at the complex parts NC cutting parameter selection, therefore cutting parameter optimization mathematical model is set up, and optimize it.

Abstract: The objective of this study was to utilize Taguchi methods to optimize surface roughness, tool wear and power required to perform the machining operation in turning metal matrix composites (MMC). The cutting parameters are analyzed under varying cutting speed, feed rates and cutting time. The settings of turning parameters were determined by using Taguchi’s experimental design method. Orthogonal arrays of Taguchi, the signal-to-noise (S/N) ratio, the analysis of variance (ANOVA) are employed to find the optimal levels and to analyze the effect of the turning parameters. Confirmation tests with the optimal levels of machining parameters are carried out in order to illustrate the effectiveness of Taguchi optimization method. The results show that the Taguchi method is suitable to solve the stated problem with minimum number of trials.

Abstract: At present, most factories choose cutting parameters only depending on experience or handbooks in production. To improve the intelligent level of cutting parameter selection, Case-Based Reasoning (CBR) is used to search rational cutting parameters. The structure of a CBR-based cutting parameter selection system is presented and its functional modules are discussed. CBR-based cutting parameter selection system is mainly composed of case base management system, cutting parameter database management system, application, interface, etc. A complete case is composed of four parts, i.e., objectives, initial conditions, constraints and results. The system adopts hierarchical searching method in combination with nearest neighbor method. It provides a scientific approach for selecting cutting parameters in actual production.
