This study takes virtual instrument technology as the development platform to complete data acquisition, pre-processing, analysis and database storage for three orthogonal components of a cutting force and the corresponding cutting temperature. Simultaneously, single-factor experimentation is adopted to establish empirical formulas of these cutting state parameters for further check analysis. Hence real-time monitoring of cutting process can be implemented to represent cutting-tool wear, failure and rationality of parameter selection in cutting state.

As the main method of high efficiency cutting Ni-based superalloy, high-speed cutting can not but intensify the cutting-tool wear for the high cutting force and cutting temperature. So, it is very necessary to study the process of cutting-tool wear and wear mechanism, especially, the effect of cutting-tool wear on the cutting force, cutting temperature and surface roughness of machined workpiece. In this paper, investigation of tool wear in high-speed cutting is proposed, the PCDTiAlN carbide insert is used in the experiment, the cutting-tool wear and the corresponding cutting force, cutting temperature and surface roughness of machined workpiece is detected. It indicates that the cutting force, cutting temperature and surface roughness of machined workpiece is changed corresponding the cutting-tool wear,the wear process of coated tool include the coated material wears and base material wears,the wear mechanism is complex.

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.

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. It indicates that the cutting force, cutting temperature and surface roughness of machined workpiece is changed corresponding the cutting-tool wear changes, and cutting-tool is serious, for example, the crater wear expands quickly; the boundary wear is obvious.
