In order to study the distribution of the stress field in the high-speed intermittent cutting process, finite element model of high-speed intermittent cutting is established. Exponential material model of the constitutive equation and adaptive grid technology are applied in the finite element analysis software AdvantEdge. The material processing is simulated under certain cutting conditions with FEM ( Finite Element Method ) and the distribution of cutting force, stress field, and temperature field are received. A periodic variation to the cutting force and temperature is showed in the simulation of high-speed intermittent cutting. Highest value of the milling temperature appears in front contacting area of the knife -the chip.and maximum stress occurs at the tip of tool or the vicinity of the main cutting edge. The analysis of stress and strain fields in-depth is of great significance to improve tool design and durability of tool.

The milling experiments were carried out using TiAlN and PCD coated carbide tools in high speed milling Ti6Al4V to compare and analyze tool wear and tool life of the two kinds of coating carbide tools. In addition, the effect of cooling and lubricating on tool wear is also studied. The results showed that fluid environment is not suitable for milling Ti6Al4V. PCD coating carbide tool can effectively increase the life of tool in high speed milling of Ti6Al4V.

Through the orthogonal test of the TiALN coated carbide tool high-speed milling of high-temperature alloy GH4169, the empirical formula of the tool life are acquired by using multiple linear regression method. On the basis of this formula, studying the absolute sensitivity and relative sensitivity of TiALN coated carbide tool life for milling speed, depth of cut and feed; The results showed that in the process of high-speed milling of high-temperature alloy GH4169, tool life decreased with the increase of milling speed, feed and depth of cut; tool life is most sensitive to the change of milling speed; change of feed take second place and milling depth is the least sensitive.
