Description
Technical Field
The invention relates to a processing method for forming a microstructure on the surface of a workpiece and a control system.
Background
The surface microtexture technology is to construct a series of microstructure arrays with certain shapes, sizes and arrangement modes on the surface of a material by utilizing a micro-machining method so as to improve/regulate the surface characteristics of the material. In recent years, with the development of micro-machining technology, surface micro-texture technology has been successfully applied in various fields such as bionics, tribology (friction reduction, tool wear reduction and adhesion reduction), microfluidics (micro-channel drag reduction) and biomedicine (implant biocompatibility improvement), and has achieved good effects.
At present, the processing technology of the surface microstructure array (microtexture) mainly comprises micro milling, laser processing, abrasive gas jet, electric spark processing, mask electrolytic processing and the like. However, the above methods have certain disadvantages, such as: the micro milling has processing stress and surface residual stress, and the texturing treatment of the surface of a material difficult to process is difficult to realize; the laser processing surface and the electric spark processing surface both have heat affected zones, and the surface roughness is poor; abrasive gas jets are only suitable for machining of brittle materials and the like.
Mask electrochemical machining (TMECM) is a special machining process for performing electrochemical machining after photoetching the surface of an anode, and the technology combines the high resolution of the photoetching technology and the high efficiency of electrochemical machining, and becomes one of the common methods for preparing the microstructure array on the surface of a metal material. In the process of the TMECM, the manufacturing of a mask plate is a very critical step, and at present, the manufacturing method of the mask mainly comprises a photo-lithography method, an electron beam direct writing method, a focused ion beam direct writing method and the like, but the methods all have the defects of high price, long manufacturing period, small mask plate area and the like. Furthermore, when the characteristic parameters of the desired array structure need to be changed, the mask plate must be reworked if the conventional TMECM process is used, which not only results in a waste of material, but also greatly prolongs the process cycle. In addition, the existing mask electrolytic machining technology is usually used for preparing a planar or large-caliber rotating surface microstructure array, and the processing of a small-caliber rotating and quasi-rotating thin-wall curved surface (such as an inner/outer rotating surface of a cardiovascular stent, a quasi-rotating profile surface of a micro gear, a cam and the like) microstructure array is difficult to realize.
