Based on cutting and vibrating theories,the dynamic behavior of micro drill is studied by using the finite element method.

Micro 3D structure machining with simple shaped electrode can't generally apply the method of common mechanical milling for the reason of electrode wear, Machining conditions and etc.

Series experiments of micro slot confirm the proposed compensation process and the algorithm.

Development of miniaturized numerical control milling machine tool used in micro-cutting;

In this paper,the main form,practicable field and technical system of micro-cutting were analyzed based on the characteristic and micro-machining demand of microstructure.

Based on a machining example, the NC turning technology for a micro-structure composed of straight groove and curve profile groove in the part's internal hole is introduced, the machining effect and some technic problems in micro-cutting are analyzed.

During the micro-electroforming process,the current density distribution in cathode surface has directly impact on the electro-deposition quality.

The effect of the rare earth nano-La2O3 added to the basic sulfamate solution on micro-electroforming process was studied.

In order to improve the micro electroforming quality of a microstructure,the characteristics of the micro electroforming process were discussed systematically and the properties of the electric field and flow field were analyzed.
