Research on rapid-charge type Ni-MH battery for electric tools application;

The esthetics characters of electric tools sculpting and human esthetics taste were combined by fuzzy theory to comprehensively evaluate electric tools sculpting.

Based on relevant theory of modular design,the paper studied modular design process of electric tools,particularly on three aspects such as module partition,modular establishment and developing of module management system based on UG.

In combination with the structural features of plating hangers,the research and application status of the solutions for stripping metal coatings on the hangers both at home and abroad are overviewed from chemical fundament of metal coatings stripping,stripping principle and existing stripping processes.

The electric discharging machining(EDM) is one of the main methods to process the Integral Impeller,in which the fabrication of the tool electrodes in EDM is the very key.

On the self-developed equipment, tool electrode and workpiece were sequentially machined with electrochemical method.

The fabrication of tool electrode was investigated and the issue on the machining shoud be concerned was discussed.

The application of Pro/E in exact forge of cone gear is stated, and Pro/E applied in cone gear and the modeling of die electrode, jigs electrode, and standard gear, as well as the NC programme manufacture of above forming by Powermill are mainly introduced respectively.
