AMR

On the basis of the powerflow theory and four-end parameter analysis method, the responses and the powerflow characteristics of the vibration transfer path system are examined. The sensitivity of non-linear damping is employed as measurement criterion. The powerflow and powerflow sensitivity are obtained and the effect on powerflow and powerflow sensitivity of dry friction damping, fluid damping and structural damping is studied. Numerical results are also presented and discussed. It is supposed to study the sensitivity of these parameters, to estimate the effect of the change of parameters, to improve the design performance.

“…Wire Electro Discharge Machine (WEDM) is one of the effective and important methods for machining precision parts in many areas, such as aeronautics and astronautics, military industry and mould industry, etc [1][2]. In China, most of wire electro discharge machine tools are High Speed -WEDM (HS-WEDM) machine [2], which has many advantages like low running cost, large thickness cutting and so on. On the other hand, because of simple control strategy of discharge and power circuit configuration, the single discharge energy of these traditional pulse power supply is unequal, and the cutting speed and the finest surface roughness is low.…”

In Wire Electro Discharge Machine (WEDM), as the big randomicity of electro discharge, single discharge energy is various. In this paper a resistor-less and half-bridge power supply is investigated based on pulse width modulation(PWM), whose single discharge energy is equal , adopting discharge control strategy of breakdown waiting. And the experiment shows the cutting speed and surface roughness of this isopluse power supply is superior to that of traditional isofrequency power supply.

“…The manufacturing industry in China today creates directly one third of the gross national product and four fifths of the entire industrial product, provides over one third of the income for national finance, and contributes to 90% of total export. The employed population in the manufacturing industry takes up 90% of the total employed population in the industry nationwide [2,3]. The key for the achievement of new industrialization in China is through the advancement of the manufacturing industry.…”

A Further Discussion on Trends in the Development of Advanced Manufacturing Technology

Shuzi

2006

This paper is a supplement to "Trends in the Development of Advanced Manufacturing Technology" (Yang and Wu in Chin. J. Mech. Eng., 39: 73, 2003) but delves deeper into it. It first points out the strategic status of manufacturing industry in state development. Then, a detailed analysis is given on the features and trends in the development of advanced manufacturing technology in a total of 12 points from three aspects: "precision," "extreme," and "culture" from the aspect of the product itself; "green," "rapidness," "saving," and "efficiency" during the manufacturing process; and "digit," "auto," "integration," "networking," and "intelligence" in view of the manufacturing method. In addition, it emphasizes that all the above aspects should be based on two base points: "manufacture" and "machinery." Finally, it puts forth the guiding ideologies for the development of advanced manufacturing technology and the aspects China should give priority to in development, while stressing on the principles of independence, innovation and "human orientation."
