Size effect, referring to mechanical properties of materials change with the geometry changes, is the basic characteristic of brittle and quasi-brittle materials.
Introduction Size effect[1-2] means the mechanical properties of the material is no longer a constant, changing with the geometry changes, For concrete materials, compressive strength and tensile strength decrease with the sections size increases, on the contrary, the fracture energy increases.
Size Effect Theory of the Concrete The strength of concrete, composed of several materials with different strength, is determined by the proportional relationship between the strength of several materials.

Many researchers also focused on the cutting tool materials and tool wear mechanism, and the studies demonstrated that the abrasion mechanism in titanium alloy machining with different cutting tool materials was adhesive and diffuse wearing.
In summary, uncoated cutting tools and the PCD are regarded as the most suitable tool material for machining titanium alloys among the current tool materials.
