In this paper,the current status of machining technology about the micro integral component is introduced,many machining methods including the NC manufacturing,the non-traditional machining and the precision casting are compared.

Combined with the geometrical simulation of machining process based on UG dynamical mounting technology and simulation of shaping law based on MATLAB finite element analysis,the computer simulation of NC-Electrochemical machining process for the complex curves and cavities of integral components is realized.

According to structural characteristics of microminiatute component, the profile parameters, which can reflect the manufacturing properties, was selected, and a numerical surface profile model including roughness and waviness was built up based on the Patir model, and the case was provided.
