The part information includes that the geometry information, such as geometry shape, dimension,etc; technique information,such as machining precision, heat treatment, material type.etc. 3) Technique process design and manage module: In accordance with inputing part information, the CAPP system decides the group, and then, searches the typical technique document of this group, disposes the technique according to regulation, at last, the appropriate technique document is gotten, which relates to the machine tool resouce database, technique resource database, material database and cutting parameters database, and so on.

Introduction Titanium nitride has been recognised as an excellent barrier material with good electrical conductivity in various metallisation structures of advanced microelectronic devices.
Apart from this, the classical field of application of TiN is as coating on cutting tools due to the excellent mechanical properties of this material such as high hardness and high wear resistance.

In recent years, white light digital speckle method (PanYiShan etc) [1] used in geotechnical material deformation damage such as research has made great achievement.
Damage and material deformation often is indivisible, and by material deformation properties and condition, it can be divided into the elastic damage, the damage elastoplastic damage and creep damage (sometimes called viscoplasticity damage), fatigue damage and spelling damage, also called dynamic damage.
Experimental process Material of experiments is selected C30 concrete, pouring in block, within materials 44010050mm, a group of 50 with incision.

Well known sensing materials are, for example, SnO2, ZnO and TiO2 [1].
These materials may overcome the disadvantages like the lack of selectivity or dependence on humidity of the established materials.

In 1938, the United States Bureau of Reclamation has developed the prototype of first generation permeable formwork which was made of thorns and wood pulp materials, and it was used in the Kentucky dam in 1941 for the first time.
The research and development of permeable formwork starts late in our country, but in recent years, research and development of lining materials have made great progress.
