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.

A strategy of toolpath generation based on Tool-Zmap geometric model has been proposed to achieve efficient finish machining of mold cavity. Considering cutting tool wear, the finish machining of mold cavity was performed using variable cutting tools of different diameter. Each cutting tool only cuts the corresponding area to avoid identifying machining characteristic and poor rigidity of cutting tool during high speed machining. Finally, the validity of presented strategy was experimentally affirmed by a machining example.

High-speed machining (HSM) has received great interest because it leads to an increase of productivity and a better workpiece surface quality. However, tool wear increases dramatically due to the high temperature at the tool/workpiece interface. Proper selection of cutting tool and cutting parameters is the key process in high-speed machining. In this paper, experiments have been conducted to high speed milling pearlitic cast iron with different tool materials, including polycrystalline cubic boron nitrogen, ceramics and coated cemented carbides. Wear curves and tool life curves have been achieved at various cutting speeds with different cutting tools. If efficiency is considered, Polycrystalline Cubic Boron Nitrogen cutting tool materials are preferred in finish and semi-finish machining. According to the different hardness of cast iron, the appropriate range of cutting speed is from 850 m/min to 1200m/min.

High speed machining (HSM) produces parts with substantially higher fatigue strength; increased subsurface micro-hardness and plastic deformation, mostly due to the ploughing of the cutting tool associated with residual stresses, and can have far more superior surface properties than surfaces generated by grinding and polishing. In this paper, a dynamics explicit Arbitrary Lagrangian Eulerian (ALE) based Finite Element Method (FEM) modeling is employed. FEM techniques such as adaptive meshing, explicit dynamics and fully coupled thermal-stress analysis are combined to realistically simulate high speed machining with an orthogonal cutting model. The Johnson-Cook model is used to describe the work material behavior. A detailed friction modeling at the tool-chip and tool-work interfaces is also carried. Work material flow around the round edge-cutting tool is successfully simulated without implementing a chip separation criterion and without the use of a remeshing scheme. Finite Element modeling of stresses and resultant surface properties induced by round edge cutting tools is performed as case studies for high speed machining of AISI 1045 and AISI 4340 steels, and Ti6Al4V titanium alloy.

In this paper, L8 Taguchi array is applied to find the most important parameters effects on the radial and tangential cutting forces of a Ti–6Al-4V ELI titanium alloy in dry high speed machining (DHSM). The experiments are performed in four cutting speeds of 150, 200, 250, and 300 m/min and two feed rates of 0.03 and 0.06 mm/rev. Also, two cutting tools in types of XOMX090308TR-ME06 of uncoated (H25) and TiAlN+TiN coated (F40M) are used. Results confirm that to minimize the resultant cutting force and radial cutting force, utilizing the lower feed rate and higher cutting speeds were considered as the best levels of factors to reach to its goal.
