Cutting Tool Wear

As the main method of high efficiency machining Ni-based superalloy, high-speed cutting can not but intensify the cutting-tool wear. So, it is very necessary to find the rule of cutting-tool wear in high-speed cutting superalloy, especially, the effect of cutting-tool wear on the cutting force, cutting temperature and surface roughness of machined workpiece. In this paper, the PCDTiAlN cemented carbide insert is used in the experiment, the value of cutting-tool wear and the corresponding cutting force, cutting temperature and surface roughness of machined workpiece is measured.

Cutting Vibration

A series of research on the interactions among tool wear, cutting force and cutting vibration were conducted through high speed milling experiment in this paper, which objected the titanium alloy as difficult-to-cut materials. The results showed that the increasing of tool wear led to enlarging the cutting force and cutting vibration; and vice versa, the increasing of cutting force and cutting vibration aggravated the tool wear in the process of machining. Besides, the variation trend of tool wear with cutting was similar to the trend of cutting force, while the variation trend between cutting vibration and tool wear was different. Especially in the sharply cutting tool wear stage, the influence of tool wear on cutting vibration became more complicated.

This study details the machinability of CFRP materials with fiber orientation set Quasi-isotropic in the orientation of (0°, 45°, 90°, -45°), plain weave type in the orientation of (0°, 45°) and at random in using High-Speed Steel (HSS), Nitride HSS, Tungsten-Carbide, TiAlN-coated tungsten carbide and Poly-Crystalline Diamond (PCD). The influences of cutting distance, cutting force, cutting temperature and tool wear on the surface characteristics of the CFRP materials are also examined. The results of our experiments reveal that the cutting force and cutting temperature increases when cutting randomly-orientedmaterials irrespective of the type of cutting tool used. The increment of the cutting force obtained was about 5% compared to cutting plain weave type oriented materials. In addition, the cutting temperature of the central portion was 20°C higher than the surface temperature. The tool wear of straight-edge type PCD tools was about 0.1 mm at 30 m cutting distance, whereas, at sharp edge, and lead angle of 30°, the tool wear reached 0.1 mm at 9 m cutting distance. Additionally, the straight-edge type cutting tool showed better results with respect to adhesion of coated materials.

This paper investigates numerical and experimental study of end milling of titanium alloy Ti–6% Al–4% V using carbide insert based cutting tool. The experiments were carried out under dry cutting conditions. The cutting speeds selected for the experiments are 20,30,40,50 mmin–1. The feed rates used in the experiment were 0.02, 0.04, 0.06 and 0.08 mmrev–1, while depth of cut is kept constant at 1.0 mm. For conducting the experiments single insert based cutting tool is based. For a range of cutting speeds and feeds measurements of cutting force, surface roughness and cutting temperature have been recorded. From the experimental study it can be seen that cutting speed has the significant effect on temperature when compared to feed/tooth. Further it is also found that cutting speed of 30 m min−1 and feed rate of 0.02 mm rev−1 could be used for machining Ti alloy. Moreover the experimental and numerical cutting force values are compared.

On Line

The wear of cutting tool degrades the quality of the product in the manufacturing processes. The on line monitoring of the cutting tool wear level is very necessary to prevent the deterioration of the quality of machining. Unfortunately there is not a direct manner to measure the cutting tool wear on line. Consequently we must adopt an indirect method where wear will be estimated from the measurement of one or more physical parameters appearing during the machining process such as the cutting force, the vibrations, or the acoustic emission etc.... In this work, a neural network system is elaborated in order to estimate the flank wear from the cutting force measurement and the cutting conditions

Machined Surface Quality

The machinability of nickel-based superalloy GH4169 is very poor, the traditional machining of GH4169 using the cutting fluids with the active additives causes environmental and health problems, which is out of the request of the sustainable development strategy. In this paper a new green cutting technology with overheated water vapor as coolants and lubricants was proposed to achieve the aim of green cutting and high productivity. Cutting experiments and tool wear tests using carbide tool YG6 under dry cutting, emulsion and water vapor were performed. The cutting force, cutting temperature, machined surface quality and tool life were investigated; the curve of flank tool wear and relation between tool life and cutting velocity was carried out. The results of experiments indicated that during water vapor condition, the cutting force and cutting temperature was reduced, the machined surface roughness was improved, and the tool life was longed, respectively, and the higher velocity was taken during the some tool wear condition compared to dry cutting. The research results show that green cutting was achieved associated with overheated water vapor cooling and lubricating, at he same time the machined surface quality and production efficiency was increased.
