Problems solved by technology
When a single wire electrode is used for processing, the stroke is too long. Due to the limitation of processing speed, the processing efficiency is greatly reduced. When the wire trajectory is complex, it is easy to produce dimensional accuracy errors of the processing structure, and it is impossible to realize the complex structure of variable cross-section symmetry. One-time precision machining
However, electrolytic machining using group wire electrodes is only suitable for the processing of structures such as group seams and group holes, and it is difficult to accurately control the position error between each wire electrode in the group wire electrode. The flexibility of processing is reduced, and it is impossible to realize the processing and forming of parts with complex cross-sections

The invention relates to a double microscale line electrode device and a method of processing a complex structure part by electrolytic machining and belongs to the technical field of precise and microelectrochemical manufacturing. A precise servo motor in the device drives the double microscale line electrode to precisely move in opposite directions or in reverse directions synchronously througha leftward rotating lead screw and a rightward rotating lead screw in the precise servo motor, and a micro numerically controlled rotary shaft drives the double microscale line electrode to rotate synchronously or rotate at individual independent angles. Under independent successive precise movement or synchronous linkage of an ultraprecise three-dimensional moving platform, an ultraprecise rotaryshaft and the precise servo motor, diversified trajectory movement of the double microscale line electrode can be achieved for processing and manufacturing complex microstructure structure parts.
Description
technical field [0001] The invention relates to a double-microscale wire electrode device and a method for electrolytically machining parts with complex structures, belonging to the technical field of precision and micro-electrochemical manufacturing. Background technique [0002] In precision manufacturing fields such as aerospace, precision instruments, micro-robots, micro-electro-mechanical systems, micro-electronics technology, and micro-sensors, metal structures with various contours are widely used. These parts are characterized by characteristic planes and datums. The surface is distributed with inclined angles, the cross-sectional shapes are various, and the aspect ratio is large. Generally, heavy metals with high Z elements, titanium alloys, hard alloys and other difficult-to-machine materials are used for processing. However, due to the low thermal conductivity, high temperature, and high strength of these materials, it is difficult for traditional CNC milling and ...
