Description
Technical field
The present invention relates to abradant jet processing method under the recombination energy field action, belong to the processing technique field of difficult-to-machine material.
Background technology
Fast development along with modern science and technology, particularly the most advanced branches of science such as Aero-Space, defence and military technology advances by leaps and bounds, for performance and the reliability that improves product, various new materials continue to bring out, and as titanium alloy and various Metal Substrate and non-metal-matrix composite, at aerospace field, obtain applying more and more widely.Because these materials all belong to difficult-to-machine material, therefore an incident process technology difficult problem also is subject to showing great attention to and paying attention to of various countries all the time.In order to solve the process technology difficult problem of difficult-to-machine material, on the one hand, the researcher of various countries is devoted to traditional Machining Technology for Cutting is improved, as the method that adopts high-speed cutting processing is carried out machining to titanium alloy component etc., but the cutting ability of difficult-to-machine material is very poor, not only very strict to the performance requirement of process equipment, the tool wear problem is also the bottleneck problem of restriction cutting of hardworking material manufacture field always simultaneously; In addition, the technical characterstic of machining has determined that it inevitably can produce surface/sub-surface damage, and the existence of these surface/sub-surface damage layers can seriously have influence on the serviceability of part, reduces its service life.On the other hand, special processing technology such as spark machined, electrochemistry processing have very consequence in the processing technique field of difficult-to-machine material.This is because electric discharge processing is by the HTHP of workpiece and electrode discharge moment generation, to realize the removal of material can realizing all metal materials and the processing that realizes the part nonmetallic materials by special processing process.But the working (machining) efficiency of spark machined is lower, surface quality is not high, surface after processing can form the re cast layer that one deck is firm, the existence of re cast layer can have a strong impact on the serviceability of workpiece, also there are the problems such as export license and complicated electrode difficult design in spark erosion technique simultaneously, and the existence of above-mentioned shortcoming has limited the range of application of spark erosion technique., also there are the problems such as electrochemistry processing electrode special difficult design simultaneously in the advantages such as it is high that electrochemistry processing has working (machining) efficiency, and surface quality is good, but the more difficult control of machining accuracy.
In order to solve electrochemistry, process the problems such as electrode special difficult design, the people such as the agro-industrial WataruNatsu of university in Tokyo have proposed to utilize the processing of electrochemistry jet to realize the new method of material removal process.The method is ejected into surface of the work by electrolyte by the special-purpose ejecting device, between workpiece and special-purpose ejecting device, adds certain voltage (workpiece connects positive pole, and the special-purpose ejecting device connects negative pole) to realize the electrochemistry of workpiece material is removed simultaneously.By research, find that the removal process of material only occurs near the zone special-purpose ejecting device center, because the electric field that the electrolyte by the special-purpose ejecting device is set up is in injection apparatus central area maximum, after departing from center, electric field weakens rapidly, utilize this technology can effectively control the machining accuracy that electrochemistry is sprayed processing, by TRAJECTORY CONTROL, can also realize having the Precision Machining of complicated shape curved surface part.By changing electric power polarity, can also realize electrochemical deposition, plated film and the technique such as painted.Therefore, the range of application of this technique is very extensive.But adopt single energy form electrolyte spray regime to add man-hour, in order to improve machining accuracy, generally adopt passivity electrolyte, utilize such electrolyte to add man-hour, the passivating film that process produces can have a strong impact on the working (machining) efficiency of the method.
In order to improve the working (machining) efficiency of electrochemistry jet processing, the people such as P.T.Pajak of Glasgow, United Kingdom Scotland university have proposed to utilize the laser assisted electrochemistry of energy composite energy form to carry out the new method of material removal process.The method adds the coaxial laser of certain energy by the injection apparatus center in the processing of electrochemistry jet, utilize laser to the auxiliary heating of workpiece, to be used for strengthening the kinetic energy of electrochemical reaction, the auxiliary passivating film that decomposes electrochemistry jet processing generation, improve the efficiency of electrochemistry jet processing with this simultaneously.Owing to adopting the energy composite energy form to process, this technology is all comparatively remarkable aspect the removal efficiency that improves material and machining accuracy.but because the method need to guarantee that laser is coaxial with the center of electrolyte jet beam, otherwise can have a strong impact on the removal effect of material, reduce working (machining) efficiency, but require laser and electrolyte jet beam center strictly coaxially from technology, to realize comparatively difficulty, and the axiality at laser and electrolyte jet beam center also is subject to processing environmental condition (as the jet beam dynamic behavior, impurity content etc. in negative pole produces in process bubble and electrolyte) impact, laser is easy to disperse to be difficult to focus on desirable zone in the electrolyte jet beam simultaneously, thereby affect the actual processing effect of this kind processing technology.Simultaneously, also there is the process equipment complexity in the method, the problems such as cost of equipment maintenance height.
The abradant jet process technology is to utilize the high velocity jet fine abrasive to the mechanical erosion effect realization of surface of the work, the removal of workpiece material to be processed.To have equipment simple due to abradant jet processing, and occupation mode is flexible, can realize the characteristics such as processing removal to multiple material, since producing the eighties in last century, aspect the cutting of various materials, processing, obtained application very widely.But research is found, while utilizing the abradant jet process technology to carry out polishing to SKD61 mould steel, in the abradant jet process, the size of the hardness of fine abrasive, shape and particle directly has influence on working (machining) efficiency and machined surface quality, when adopting the #2000SiC abrasive material to add man-hour, working (machining) efficiency is higher, and surface roughness value can reach Ra0.28 μ m, and adopts the #8000SiC abrasive material to add man-hour, surface roughness value can reach Ra0.13 μ m, but working (machining) efficiency has reduced by 50%.Above analysis can be found out, adopts the abradant jet of single energy form to add man-hour, and working (machining) efficiency and surface quality are restrictions mutually.
