However, the titanium alloy has the properties of low elastic modulus, high elastic deformation and low thermal conductivity, which reduce the machined surface quality [1-4].
Therefore, the main factors that affect the cutting force are not only the characteristics of the material itself, but also the tool wear, cutting conditions, etc
But as the cutting speed increased further (higher cutting speeds), thermal softening effect is not the single factor which affected cutting force, strength of materials increased resulting in the decrease of cutting forces and the trend became slow.
As shown in Figure 9, tool wear is one of the important factors that affects the cutting temperature.

It shows that failure usually occurs in the cooling stage, because the creep is less affected at this time.

Several groups of experiments were carried out to investigate the effect of the specimen configuration and the loading speed on the tensile properties.
Mechanical properties in tension are very important to establish the material properties for structural design, installation and maintenance [1].
Since there isn't any standard for the multi-axial tensile testing, the factors, such as the configuration of the specimen and the loading speed, which might affect the testing results were investigated.
This shows that the mechanical properties in warp direction of the coated membrane materials play an important role in the tensile failure under multi-axial loads, whatever the initial crack length and the crack orientation is.
This emphasizes the importance of the tensile properties in warp direction when the coated membrane materials are suffering from multi-axial tensile loads.

Because Box-Behnken design has fewer design points, they are less expensive to run than central composite designs with the same number of factors.
Box-Behnken Design also ensures that all factors are never set at their high levels simultaneously [12 - 14]. 3.
