Surface engineering is one of the applications and contains surface alloying/cladding, surface melting/remelting, surface amorphization and surface hardening/shocking.
The application of laser for material processing are broadly divided into four major categories; namely, laser-assisted forming, joining, machining and surface engineering.
Surface engineering belongs to high power applications and contains surface alloying/cladding, surface melting/remelting, surface amorphization and surface hardening/shocking [3].
LSP has been developed as a practical process amenable to production engineering.

Abstract.
Three cutting tools, YG610, Si3N4 ceramic tool and CBN were adopted for heat cutting deposited materials.
The deposited materials whose hardness is HRC60 were cut with all kind of cutting parameter.
So the Si3N4 ceramic tool is not suitable for heat cutting hardness materials.

What the manufacturing requires from the design phase are a bill of materials, routes of manufacturing processes, and manufacturing documentation.
The key condition for effective concurrent engineering and cross-enterprise engineering is integrated computer environment for design and manufacturing: a common platform for computer-aided systems for product development [2].
Connector functionalities: - mapping CAD objects with materials identifiers (for purchased parts, materials, elements), - viewing attributes of materials such as name, price, unit of measure, etc., - preparation of the bill of materials (BOM) for the integrator, - preparation of links to CAD drawings for the integrator, - access to the data warehouse and MRP, - on-line access to costs.

Abstract.
Nuclear fusion is a promising source of environmental friendly energy for the future, and the ultra-fine grained Tungsten (W) is a hopeful candidate material to be used as plasma-facing materials (PFMs), which are the key materials in the International Thermonuclear Experimental Reactor (ITER), for its many useful advantages.
Plasma facing materials (PFMs) is one of the key materials in ITER which will work in extreme conditions, including complex thermal, mechanical, and chemical loads as well as strong irradiation.
Over the past few decades, many materials were tested as PFMs including both low-Z materials (Be, C, carbon fiber composite (CFC), B4C, etc.) and high-Z (W, Mo, etc.) materials [2, 3].
However, the embrittlement of Tungsten material restricts its application on plasma-facing materials (PFMs) [4, 5].

This Technology can be suitable both to traditional masonry structure and to new wall materials masonry structure, especially to seismic appraiser and reinforcement calculation of masonry structure.
This technology can support scientific basis to quality examination and assessment of new wall materials and analysis of engineering quality accident.
To guarantee the security and healthy development of the new wall materials structure, experimental study of the comprehensive performance of masonry structure must be speeded up.
c) When raw material information of masonry in the reinforced and reconstructed houses were lack, or design specification of new wall materials is deficiency, testing masonry shear strength with drilled core method can provides the basis of design or appraisal reinforcement.
This technology can support scientific basis to quality examination and assessment of new wall materials and analysis of engineering quality accident.

Based on the integration of CAD and CAE, a variant design method with the function to satisfy engineering constraints is put forward.
Some key technology problems of variant design method, such as how to integrate CAD/CAE and with the function to satisfy engineering constraints, are not resolved yet.
In the design of mechanical products, CAE technology has became the main way of solving engineering analysis in recent years.
Therefore, this repetitive larger engineering analysis problem can be solved through a automatic analysis process templates based on the parameter.
