Abstract
The invention relates to a processing method of a three-dimensional microstructure prepared by minute electric sparks based on sheet electrodes. The processing method includes establishing three-dimensional microstructure CAD (computer-aided design) geometric models first, establishing three-dimensional minute electric spark electrode CAD geometric models corresponding to the established three-dimensional microstructure CAD geometric models, slicing the three-dimensional minute electric spark electrode CAD geometric models in dispersedness, transforming disperse slices geometric models into a group of slice electrode data models in mutually parallel, slicing corresponding slice electrodes on a slice electrode material one by one by a slice slicing system according to the slice electrode data models in a computer to acquire a group of slice electrode array, and performing minute electric spark machining. With the manufacturing method, electric discharge machining via large-size scanning and milling by layers of cylindrical microelectrodes is avoided when two-dimensional slice electrodes perform electric discharge machining, and an up and down type moving electric discharge mode can effectively increase machining efficiency and reduce microelectrode loss.
Description
technical field [0001] The invention relates to a processing method for a three-dimensional microstructure, in particular to a processing method for preparing a three-dimensional microstructure based on a thin electric discharge of a sheet electrode. Background technique [0002] Generally, the microstructure is defined as: at least on the two-dimensional scale, the article with submillimeter or micron-scale micro-feature structure is called micro (structural) parts. [0003] The preparation of three-dimensional microstructures by micro-electrode discharge machining is one of the mainstream processing methods for preparing three-dimensional microstructures. The main methods for preparing three-dimensional microstructures using micro-electrode discharge machining are: [0004] (1) Connect several layers of two-dimensional sheet electrodes to superimpose and fit a three-dimensional microelectrode, and use the three-dimensional microelectrode for electrical discharge machining...
