However, the difficulty of forming its industrial processing is increased by the high strength and high hardness of nitride ceramic materials, so the research of nitride ceramic materials in ultra-precision processing problem has prominent significance.
Laser-assisted machining technology [16] (LAM) use the strong laser to heat local of ceramic materials, making its surface materials brittle deformation by in high temperature into plastic deformation, at the same time take the principle of the traditional tool to remove that part of the material.

Tourassis1,a 1School of Science and Technology, Nazarbayev University, Astana, Kazakhstan avassilios.tourassis@nu.edu.kz Keywords: mechanical assembly, disassembly lines, end-of-life processing Abstract.
With growing interest in the recovery of materials and subassemblies from consumer products at the end of their useful life, there is a need to develop decision-making methodologies that determine how to maximize the environmental benefits of end-of-life processing while minimizing recovery costs.
Thus, landfills are constantly pilled up with hazardous and/or valuable materials, while the useful life of products is continually reduced.
During this phase materials are chosen, manufacturing methods are designed, the amount of energy consumed during production and use is determined, and how the product will be treated after its useful life is decided upon.
Summary With growing interest in the recovery of materials and subassemblies from consumer products at the end of their useful life, there is a need to develop decision-making methodologies that determine how to maximize the environmental benefits of end-of-life processing while minimizing recovery costs.
