Abstract

The invention discloses an electrolytic machining method for a porous structure with a gradually-changed aperture, a terminal and a storage medium. The method comprises the steps of acquiring a gradually-changed aperture porous structure model of a workpiece to be machined; acquiring a unit model of the gradually-changed aperture porous structure model; segmenting the gradually-changed aperture porous structure model by taking the unit model as a segmentation unit, and segmenting the gradually-changed aperture porous structure model into a plurality of unit models; numbering the unit models according to a preset direction; and according to the serial numbers of the unit models, calling a feeding device and an electrolyte supply device, using an aperture adjusting module to sequentially conduct electrolytic machining on gradually-changed aperture machining areas corresponding to the unit models, and acquiring the gradually-changed aperture porous structure. According to the electrolytic machining method for porous structure with the gradually-changed aperture provided by the invention, the efficiency of simultaneously machining multiple gradually-changed aperture deep holes can be improved, discharge of electrolyte and electrolytic products is promoted while the multiple gradually-changed aperture deep holes are machined through cooperation of a moving electrode and an variable-diameter electrode, and the electrolytic machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to an electrolytic machining method, a terminal and a storage medium of a porous structure with gradually changing apertures. Background technique [0002] In electrolytic machining, the size of the tool electrode machining aperture is usually controlled by controlling the magnitude of the pulse voltage. When it is necessary to expand the processing aperture of the tool electrode, the pulse voltage of the tool electrode is increased to obtain a larger processing aperture; but when the pulse voltage is increased, it is easy to break down the processing gap between the tool electrode and the workpiece, causing the inner wall of the workpiece to be processed and The tool electrode is directly short-circuited. After the short circuit, the tool electrode and the workpiece will be burned, resulting in the loss of the tool electrode and the workpiece, affecting the normal op...

AI Technical Summary

Problems solved by technology

When the processing aperture of the tool electrode needs to be enlarged, the pulse voltage of the tool electrode is increased to obtain a larger processing aperture; however, when the pulse voltage is increased, it is easy to break down the processing gap between the tool electrode and the workpiece, causing the inner wall of the workpiece to be processed and The tool electrode is directly short-circuited. After the short circuit, the tool electrode and the workpiece will be burned, resulting in the loss of the tool electrode and the workpiece, affecting the normal operation of the electrolysis and reducing work efficiency; hole, or to process multiple deep holes with different diameters, such as fine nozzles, porous structures, etc., the processing efficiency of a single tool electrode is extremely low, and it is difficult to control the diameter change process when using multiple tool electrodes. Machining accuracy cannot be guaranteed
