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 paper is concerned with the effect of cutting parameters on surface microstructure of titanium alloy TC17 in high speed milling with the carbide cutting tools by single factor experiment. It will be provided experimental evidence for optimization cutting parameters and surface quality control of titanium alloy parts in high-speed cutting process. It is observing microstructure with Germany's Leica DMI 5000M inverted metallurgical microscope. The results show that in the range of experimental parameters, the effect of milling speed, feed per tooth and milling depth on surface microstructure in high-speed milling of titanium alloy TC17 is little. There is no obvious phase change, as indicating that most of the heat generated by chip away, little heat incoming workpiece, under the conditions of high speed milling titanium alloy TC17.

For its good processing flexible, economic and environmental protection performance, hardened steel GCr15 is used widely in car and energy industry. Although surface quality in machining process is not controlled well, that restricts application of hardened steel GCr15 extensive to a certain degree. Therefore, this study revealed the effect of cutting parameters on surface roughness. Also influence of cutting conditions on surface morphology and organization generation mechanism of subsurface were stuied for high-speed cutting hardened steel GCr15. Appear reasons of plastic side flow on surface was researched. Also, effect of tool wear on surface quality was studied as well. The research results provided theoretical basis for rational choice for high speed hardened steel cutting process.

Magnesium alloy is a material with a high strength to weight ratio and is suitable for various applications such as in automotive, aerospace, electronics, industrial, biomedical and sports. Most end products require a mirror-like finish, therefore, this paper will present how a mirror-like finishing can be achieved using a high speed face milling that is equivalent to the manual polishing process. The high speed cutting regime for magnesium alloy was studied at the range of 900-1400 m/min, and the feed rate for finishing at 0.03-0.09 mm/tooth. The surface roughness found for this range of cutting parameters were between 0.061-0.133 µm, which is less than the 0.5µm that can be obtained by manual polishing. Furthermore, from the S/N ratio plots, the optimum cutting condition for the surface roughness can be achieved at a cutting speed of 1100 m/min, feed rate 0.03 mm/tooth, axial depth of cut of 0.20 mm and radial depth of cut of 10 mm. From the experimental result the lowest surface roughness of 0.061µm was obtained at 900 m/min with the same conditions for other cutting parameters. This study revealed that by milling AZ91D at a high speed cutting, it is possible to eliminate the polishing process to achieve a mirror-like finishing.
