PCBN cutting tools is in high speed, high temperature and high pressure environment when high speed precision hard cutting hardened steel. Shear extrusion and slip effect in high speed cutting, cutting tools wear mechanisms are different from common cutting, even cutting tools wear mechanisms in high speed is in research stage at present. In this paper, coated PCBN cutting tools wear mechanisms in high speed cutting(v=200~600m/min) GCr15 (HRC62-64) is studied, it is helpful to obtain cutting tools structure design, cutting parameters and improve cutting tools use efficiency.

The experimental research on the wear mechanics and the tool life of TiN coated cemented carbide cutting tool in high speed milling of the Rogers/ Duroid RT6010 aluminum base microwave printed circuit board is carried out in his paper. The SEM is used to observe the wear morphology of the rake and flank face of cutting tools. The wear mechanisms of TiN coated tool include abrasive wear, adhesive wear and diffusion wear. It is shown that the abrasive wear is the main reason of cutting the complex material. In this paper, the wear mechanisms are an analyzed in details. The research results are contributive to choose proper high-speed cutting tools and parameters.

The history and application of the FEA are briefly presented in this paper. Several key technologies such as the building of material model, the establishment of the chip - tool friction model as well as meshing are described. Taking the high-speed cutting of titanium alloy (Ti - 10V - 2Fe - 3Al) as an example , reasonable cutting tools and cutting parameters are determinted by simulating the influences of cutting speed, cutting depth and feeding rate on the cutting parameters using FEA.

The unbalanced vibration of the spindle rotor system in high-speed cutting processes not only seriously affects the surface quality of the machined products, but also greatly reduces the service life of the electric spindle. However, since the unbalanced vibration is often distributed on different node positions, the multinode unbalanced vibration greatly exacerbates the difficulty of vibration control. Based on the traditional influence coefficient method for controlling the vibration of a flexible rotor, the optimal influence coefficient control method with weights for multinode unbalanced vibration of flexible electric spindle rotors is proposed. The unbalanced vibration of all nodes on the whole spindle rotor is used as the control objective function to achieve optimal control. The simulation results show that the method has an obvious control effect on multinode unbalanced vibration.

High-speed steel (HSS) turning tools was designed and sharpened according to the angles of the complex shape cutting tools. CrAlTiN coating was deposited using unbalance magnetron sputtering plating technique. By dry turning tests, the wear characteristics and wear mechanisms of the face were investigated. The results show that the face wear of the coated HSS tools is obviously different from that of the uncoated tools, the crater width is smaller, the boundary is jagged and the lowest position is away from the major cutting edge. Adhesive wear and local adhesive wear are the main wear mechanisms.

With the development of high-speed machining technology, new technical requirements have been put forward for the clamping of high-speed cutting tools. The traditional clamping methods can not meet the needs of high-speed machining. In this paper, the comprehensive performance of high-speed chucks is systematically compared and analyzed, and the characteristics and main application areas of various high-speed chucks are sorted out, which provides a theoretical basis for scientific and rational selection of chucks.
