As a sustainable model of modern manufacturing industry, green manufacturing is one of the essential solutions of the manufacturing environment pollution problems. Green cutting technology is the base and key of green manufacturing and will be the inevitable trend of cutting technology. High speed machining technology is a kind of the advanced manufacturing technologies which have superiorities as low cost, high efficiency, good processing quality and are suitable for machining thin walled workpieces and difficult-to-cut materials, and the relative problem has attracted scholars' attention from all over the world. From the perspective of green manufacturing, research results of high speed machining hardened steels are reviewed, including cutting force, cutting temperature, selection and optimization of processing parameters and machining quality, and conclude that high speed cutting is one of the key technologies in implementing green manufacturing and cleaner production. Finally, its future works of the research are discussed.

With putting the response surface methodolody and design theory into the programming of LabVIEW8.6, the process parameters optimization system is designed. The system can realize the function of test project design,online data acquisition, response surface model building and process parameters' optimization, which can greatly reduce the calculated amount of modeling and optimization. Taking 45 steel milling experiment for example, the models of surface roughness and cutting force are established by using the optimization system, taking the minimum surface roughness value as target and optimizing the process parameters, which provide practical support tools for further analysis of process parameters on the effect of processing quality

Green manufacturing is a modern manufacturing pattern taking comprehensive consideration of the environmental influence and resources consumption, it is not only a new approach that aims at realizing Eco-Industry and sustainable development of the society, but also a critical path to implement the source control of the environment pollution. Research progress and the development trend about green manufacturing at home and abroad are summarized in detail from process resource environmental attribute analysis and evaluation, the process route decision-making. Then, the uncertainty factors for green manufacturing in the production process are analysed. Finally, some problems about the production process robust optimization decision are discussed.

Large loop source TEM method has played an important role in minerals and engineering exploration. But there is a strong border effect when one explains by central loop later-time apparent resistivity. In this paper, a method was used to calculate all-time apparent resistivity by magnetic dipoles composing loop. For 1D forward data, all-time apparent resistivity was computed and compared with later-time apparent resistivity. Conclusions have been drawn that all-time apparent resistivity has no border effect on homogeneous ground model; but for complex layered model, all-time apparent resistivity border effect is reflected in vicinity of false extreme point of apparent resistivity curve, and is much weaker than later-time apparent resistivity border effect. The conclusions are conducive to a correct understanding of using all-time apparent resistivity to eliminate border effect and guide correct interpretation of measurement data.
