The text should be set to 1 line spacing. The abstract should be centred across the page, indented 17 mm from the left and right page margins and justified. It should not normally exceed 200 words The titanium alloy called “strategic metal” is a typical refractory material that causes high temperature and vibration during cutting due to its high strength, low thermal conductivity and low elastic modulus. In the processing process, the tool wear is serious, and the accompanying cutting heat and cutting vibration are coupled to each other and change with time. Studying the temperature and vibration characteristics in the processing process is conducive to further understanding of cutting mechanism, better controlling temperature and vibration, improving cutting processing quality and reducing production cost. This paper reviews the current situation of cutting temperature and cutting vibration at home and abroad. Scholars focus on the influence of cutting factors on temperature and vibration, based on finite element simulation and mathematical modeling, and the research on temperature and vibration coupling of titanium alloy cutting should be further strengthened.

There are lots of titanium alloy parts which have large-scale micro-structures in astronautic structure and medical implants, so the micro milling becomes one of the effective processing methods in getting the surface micro-structure. Because the titanium alloy has high caking property in processing, it needs a research on the cutting heat and force in order to get better machining precision and surface quality. According to the finite element theory in elastic and plasticity, the influence of cutting speed to the cutting heat and force is got by finite element simulation analysis to the titanium material TC4 in cutting process. It can get the simulation results of cutting heat and force in the micro milling processing by finite element analysis, and then compared, the basic influence which the cutting speed to the cutting heat and force is got. The correctness of the result is checked through cutting experiments.

Coupling Characteristics

Abstract The thermo-mechanical-vibration coupling characteristics of turning system has always been an important research topic in the field of machining, and the material, states and performance of cutting tools will directly affect this coupling characteristics. In this paper, a synchronous testing system for cutting temperature and cutting vibration is built to collect the cutting temperature and cutting vibration near the tip of three worn tools D1 (new blade), D2 (moderately worn blade) and D3 (severely worn blade). Based on the test data and the grey correlation theory, the coupling characteristics of cutting temperature rise and cutting vibration of tools in different wear states are analyzed. Based on the experimental data and least square method, (1) the regression model of cutting temperature rise about cutting vibration and cutting parameters (2) the regression model of cutting vibration about cutting temperature rise and cutting parameters have been established respectively. The undetermined parameters and correlation coefficients are obtained by MATLAB software programming. The research show that the coupling of cutting heat and cutting vibration of tools D1 and D2 is one-way coupling, that is, cutting vibration significantly affects cutting heat, but cutting heat has little effect on cutting vibration, while the coupling of cutting heat and cutting vibration of tool D3 is a bidirectional coupling.

Machining Performance

Titanium has been perceived as a material that is difficult to machine. Manufacturers are known that, with proper procedures, titanium can be fabricated using techniques no more difficult than those used for machining SS316. The machining of hard workpiece materials requires significantly harder cutting materials. Advancements in the aerospace, nuclear and other industries require the enhanced in-service performance of engineering components. These requirements have resulted in a large scale development and use of heat-resistant and high-strength materials, such as Ti6A4Valloys, which pose considerable machining problems. In this analysis on machining of titanium alloy using cubic boron nitride (cBN) tools, the machining performance was evaluated in terms of cutting force, specific cutting pressure, cutting temperature, chip strain and surface finish. The studies of turning machinability of titanium alloy using round tee-lock cubic boron nitride (cBN) inserts have been presented. A series of turning experiments were performed with cubic boron nitride (cBN) inserts with the objective: To determining the effect of cutting variable on the tool life. To investigate the effect of cutting speed and feed rate on the surface roughness while using round tee lock inserts. A good surface finish of 0.5 to 1 micron was obtained for cutting speed between 15 45 m/min, feed of 0.10 to 0.20 mm/rev and depth of cut of 1 mm and also find the stress intensity in two different axis will be studied.

Titanium alloy is widely applied in various fields, but it’s a sort of difficult-to-cut material. In this paper, DEFORM-3D is used to carry on a simulation of PCD tool milling Ti6A14V. Variation curves of cutting temperature and cutting force are obtained by changing cutting speed, feed per tooth and axial cutting depth. Further, the effect of cutting parameters on cutting temperature and cutting force is revealed. The research shows that cutting temperature and cutting force increase with cutting parameters. In addition, single factor experiments are conducted to verify that the results of the experiments are in consistent with those of the simulation, and that the simulation model is correct. The results will provide new methods for studies of cutting temperature and cutting force of PCD tool milling Ti6A14V.

A high temperature is produced in the process of precision milling of titanium alloy, and the cutting temperature can be effectively reduced by placing a micro-texture on the tool surface. In order to study the milling temperature of micro-textured ball-end milling cutter in milling titanium alloy under the combined action of a blunt radius with different edges and a micro-texture with different parameters, a new method based on micro-element theory and the generation and transmission of cutting heat has been established. At the same time, the influence of different radii of blunt edges on the milling temperature is simulated by the finite element method and experimentally verified to explore the influence of different radii of a blunt edge and micro-texture parameters on the milling temperature. Taking the milling temperature as the evaluation index, the optimum parameters of micro-circular pit texture are as follows: the diameter of micro-circular pit is 40 micron, pit spacing is 225 micron, distance from cutting edge is 100 microns, and radius of the blunt edge is 60 microns.
