High-powered alloy (wait like high temperature alloy, titanium alloy, high strenth steel) , composite material, hard fragile data (like pottery and porcelain of optical glass, project and functional crystal) wait for advanced material to have superior performance, wider and wider application receives in the domain such as aviation, spaceflight, war industry, electron and car. Composite material has density low, mix than intensity taller than modular quantity, can design a gender strong, corrosion resistance fatigue resistance can be can good, good as good as structural dimension stability wait for an advantage, basically use at making to be like cabin of beat of undercarriage of wing, tail vane, Buddhist templeput on the brakes, apply the brake, instrument in aerospace domain paragraph, the complex structural member such as bracket and spare parts. These courses shape on the composite material structural member of preparation and spare parts, the opening that a lot of join are assembled and accessory installation uses, window, model the need such as antrum and face of installation fixed position undertakes accurate machining. The composite material of aerospace domain model and structural member of hard fragile data and spare parts are shown 1 times like the graph. These structural member and spare parts are mixed to treatment precision not only treatment quality demand is high, and very high to machining efficiency to also have demand. Because hard fragile data has these composite material,tall, brittleness mixes hardness greatly wearability is good wait for a characteristic, material cutting processability is poor, demand of spare parts treatment is high, use traditional machining method and treatment tool very hard to undertake machining. Accordingly, the tall qualitative efficient nicety that how implements part of difficult treatment material machines the task that already made current domestic and international attention. To get used to the applied demand that all sorts of advanced material enlarge ceaselessly, on one hand, traditional machining technology passes the ceaseless newer development of oneself and the confluence with other and relevant technology, in a few difficult treatment material machines a domain (mix in mould treatment, aluminium alloy especially treatment of titanium alloy structural member) the advantage that showed treatment precision and treatment efficiency side. On the other hand, the non-traditional machining method that the energy such as benefit consumed, report, sound, hot, chemical, magnetism and nuclear energy has machining (include cut of water of laser, supersonic, electric spark, electrochemistry, high pressure to wait) got rapidder development, in the difficult treatment such as a few high-powered alloy and hard fragile data material machines a domain to show definite advantage. But, no matter be traditional machining, still be non-traditional machining method, majority is to use onefold energy to undertake machining directly, the respect waits to be put in certain defect and confine necessarily in life of quality of treatment efficiency, precision, surface and tool. Then, the compound processing technique of the integrated function that uses a variety of form energy appeared. Compound processing technique is OK the requirement according to treatment material character and treatment precision and efficiency, those who adopt conventional treatment and non-traditional machining method is compound, of method of different non-traditional machining compound the new compound treatment method that waits for a variety of forms to combine each to provide a characteristic, obtain a dominant position complementary, make one of significant progress way of machining technology. Supersonic treatment begins to apply at a kind of of industrial domain very effective non-traditional machining method as the development at the beginning of 20 centuries, special agree with all sorts of hard fragile data such as treatment glass, pottery and porcelain, quartz, diamond, silicon, already got applied extensively. What will supersonic treatment and traditional cutting treatment couple form new processing technique is a kind of typical compound processing technique, the research that comes for years and applied practice make clear, this one compound processing technique developed machining and supersonic treatment adequately already the advantage of these two kinds of processing technique, made up for the confine of two kinds of technologies and inadequacy again, have a few outstanding advantages consequently. Processing technique of supersonic and auxiliary cutting can reduce cutting force effectively not only, improve treatment quality, reduce cutting tool wears away and improve treatment efficiency, and extended can machine material and the suitable scope that can machine a spare parts and applied domain. In recent years, domestic and international researcher began much research in the light of the treatment of supersonic and auxiliary cutting of difficult treatment material, a few machine tools produced business to still develop supersonic and auxiliary cutting to machine a machine tool. Processing technique of supersonic and auxiliary cutting already was machined into component of embarrassed treatment material in one of main and advanced processing technique, have fundamental applied value and wide applied perspective. The technique that spare parts of material of difficult treatment of the model in waiting for a domain in the light of aerospace processes the article needs setting of application of sue for peace, combine the research positive result of author and domestic and international scholar, introduced the principle of processing technique of a few kinds of supersonic and auxiliary cutting, characteristic and applied effect, and a few new progress of this one compound processing technique. The principle of processing technique of supersonic and auxiliary cutting, system and classifying supersonic and auxiliary cutting to machine is to be in in traditional cutting treatment on the foundation that tool and workpiece move relatively, bring to bear on on cutting tool or workpiece supersonic vibration, in order to obtain the treatment method of better treatment function. In process of treatment of supersonic and auxiliary cutting, to be being machined through the tool the machinery of material is mixed supersonic and compound action, make tool and mechanism of the action that be mixed by the osculatory condition of treatment material produce change, basically pass mechanical cutting action, high frequency small bump action and supersonic cavitation action to wait undertake material purify. As a result of supersonic vibration introduce, changed material purify mechanism, reduced the attrition force between tool and workpiece, reduced the osculatory time of tool and workpiece, enhanced a tool the cutting purify action to workpiece, raised material purify rate effectively thereby, reduce cutting force, reduce heat in metal cutting, reduce cutting tool to wear away, improvement machines precision and quality. System of treatment of supersonic and auxiliary cutting basically transmits lever of system, supersonic transducer, supersonic luffing, tool or workpiece, cooling fluid by supersonic power source, supersonic energy the composition such as supply unit. In process of treatment of supersonic and auxiliary cutting, supersonic power source is more than generation the high frequency and telegraphic date of 15kHz through supersonic generator, power of the output after magnifying through power is supersonic signal, through transmitting systematic general power supersonic signal transmits supersonic transducer, the machine that repass exceeds sonic transducer to change telegraphic name into corresponding frequency is oscillatory, through supersonic luffing lever the extent of will mechanical vibration increases, transfer tool or work, make its produce supersonic vibration, realize treatment of supersonic and auxiliary cutting. The kind that machines according to supersonic and auxiliary cutting is different, the classification of processing technique of supersonic and auxiliary cutting is shown 2 times like the graph. The article combines the treatment of spare parts of material of aerospace difficult treatment, introduced a few kinds of advanced processing technique such as supersonic and supersonic and supersonic and auxiliary turning, auxiliary bore, auxiliary grinding and supersonic and auxiliary cut. Technology of supersonic and auxiliary turning is supersonic and auxiliary turning is to be on base of movement of common turning machine tool, bring to bear on on lathe tool supersonic vibration. Supersonic and oscillatory direction basically has along the vibration with workpiece tangential direction of rotation and the vibration along feed direction. Graph the 3 supersonic and auxiliary turning that go up in common center lathe for a kind of installation that the author develops process unit. Use get together brilliant diamond (PCD) be open to traffic of cutting tool general is cut and the appearance of treatment surface form of composite material of carbon fiber of supersonic and auxiliary turning and cutting tool wear away if contrast pursues 4 show 5 times with the graph. Machine exterior posture to compare with common turning, carbon fiber of surface of supersonic and auxiliary turning and matrix transfer position is relative smoother, surface of carbon fiber composite material machines quality to be improved apparently, cutting tool wear extent can be reduced about 30% the left and right sides [1-2] . Use general of hard alloy cutting tool to connect the high temperature alloy such as turning and Ni718 of supersonic and auxiliary turning and C263 to connect turning to machine quality to undertake contrasting experimenting making clear with general, the treatment surface surface roughness of supersonic and auxiliary turning reduces 25%~50% , circularity raises 40%~50%[3] . Supersonic and auxiliary turning returns applicable at aluminium base the metal such as carborundum base the treatment of composite material, with common turning treatment compares exterior surface roughness to be able to be reduced 25% the left and right sides, cutting force reduces 1/3~1/2[4] . Supersonic and auxiliary turning serves as advanced compound processing technique, already waited for boat aviation accident to machine material spare parts to machined a domain to obtain important applying in body of embryo of engine axis, impeller, casing and piston. Planar is supersonic and elliptical oscillatory turning (UEVC) it is the method of a kind of treatment that new development rises. At present the drive of UEVC basically includes two kinds of kind: Means of resonance of a kind of dispute, basically be the straight drive structure that is based on parallel configuration to press report to fold caboodle and mutual and perpendicular configuration to press report to fold caboodle at present, this kind of elliptical and oscillatory need stimulates Zhen Yuan twice at the same time brace up, its job principle and the treatment device that are based on this principle development are shown 6 times like the graph [5] . Another kind is resonance means, advocate if use the two mode vibration of luffing lever,combination realizes elliptical vibration, its job principle is shown 7 times like the graph. Nextpage considers to make clear, this kind of method can reduce cutting force not only, improvement machines precision and exterior quality, reduce cutting tool to wear away, and can realize cutting of brittleness material ductility, can watch treatment with Yu Hong already, also can undertake imperceptible structure is machined. In last few years method of this kind of treatment is paid close attention to by the height of international academia and engineering group. In addition, the company of university of name ancient house teachs the concept that waited for a person to still put forward three-dimensional UEVC originally, the newest progress that represented UEVC [6] . Supersonic and auxiliary auger cut a technology supersonic and auxiliary auger cutting a technology is the treatment that cuts a machine tool in tradition getting on athletic base, get in what rotate cut supersonic vibration brings to bear on on the tool, implementation is supersonic and auxiliary auger cut. The graph is shown 8 times what develop for the author is supersonic and auxiliary auger cut unit. Supersonic and auxiliary get those who cut earlier application to wait for difficult treatment material at titanium alloy, high temperature alloy and composite material cut treatment. Use hard alloy bit supersonic and auxiliary auger cut and common get the Jigaowen that cut nickel if the exit form appearance of alloy material and appearance of the form that cut bits pursue 9 with the graph 10 are shown. The result makes clear, supersonic and auxiliary get cut export burr is small and little, cut bits to be intermittent cut bits, benefit the eduction at cutting bits. With common auger cut treatment to be compared, supersonic and auxiliary get the exterior surface roughness that cuts high temperature alloy to be able to reduce 60%[9] . Use WC hard alloy broach is supersonic and auxiliary auger when cutting material of Ti6Al4V titanium alloy, cutting force is compared common auger cut reduce 20% the left and right sides [10] . Current, supersonic and auxiliary auger it is difficult in airframe of spacecraft, plane and engine to cut perspective of fundamental application value and application is had in the treatment of alveolus of the fixed position aperture that machines material key component, join aperture, cooling Kong Heshen, special assemble in the treatment of aerospace structural member in, can use between titanium alloy envelope and composite material envelope and alloy framework to assemble join aperture to machine. Composite material / the bore treatment of alloy nappe, can decrease bradawl to cut force, prolong cutting tool life, reduce alloy to cut the bits loss to composite material continuously, improve bore quality. Technology of supersonic and auxiliary grinding is supersonic and auxiliary grinding technology is to use eletroplate or the solid knot of agglomeration law preparation exceeds hard abrasive (diamond and cubic nitrogen change boron) abrasive tool, in the compound treatment method with the supersonic and oscillatory inflict on abrasive tool or workpiece. According to bringing to bear on the means of supersonic vibration differs, cent is two kinds of forms: One kind is to be on the foundation of traditional grinder, bring to bear on through be on workpiece supersonic vibration, realize treatment of supersonic and auxiliary grinding. The graph shows the typical and supersonic auxiliary grinding that passes supersonic to bringing to bear on on workpiece vibration to undertake machining to be in a kind on grinder of traditional horizontal plane 11 times to process unit [11] . Another kind is to use numerical control machine tool or machining center, will supersonic vibration brings to bear on to realize supersonic and auxiliary grinding to machine on rotating abrasive tool, also call rotate supersonic treatment (RUM) . The graph shows what develop for the author 12 times to use supersonic vibration to rotate the supersonic and auxiliary grinding of the tool processes a system. System of treatment of supersonic and auxiliary grinding includes transform device of supersonic treatment power source, supersonic power, supersonic oscillatory knife handle, abrasive tool and treatment machine tool to wait, inside the supersonic and oscillatory knife handle in this system compositive have supersonic transducer and transmit ultrasonic device, use general knife handle (wait for knife handle series like HSK, BT and SK) the main shaft join of structure and different numerical control machine tool or machining center, can place the abrasive tool that holds the different configuration such as cup emery wheel, parallel emery wheel, hollow wheelhead, columnar wheelhead, globose wheelhead. The axial that this system uses abrasive tool is supersonic vibration and whirligig, the treatment that combines numerical control machine tool or machining center moves, can realize circle of planar, inside and outside face, make hole, model the supersonic and auxiliary grinding of antrum and complex curved surface. It is difficult that the author used supersonic and oscillatory knife handle to place emery wheel of diamond of the plating that hold phone to machine pottery and porcelain of carborundum of agglomeration of composite material of carbon fiber composite material, aluminium radical carborundum, reaction and optical glass to wait treatment material obtains better treatment result. Use phone among them cup form emery wheel undertakes plating diamond the treatment surface after supersonic and auxiliary planar grinding and common grinding and appearance of form of emery wheel surface are like carbon fiber composite material respectively graph 13 show 14 times with the graph. The tilt of exterior fiber silk that the result makes clear to supersonic and auxiliary grinding is machined is less, edge does not have burr; The tool surface after supersonic and auxiliary grinding grinds bead to wear away small, tool surface did not jam almost phenomenon; Force of the grinding when supersonic and auxiliary grinding can be reduced about 50% , improvement of exterior surface roughness makes an appointment with 10%~30%[13] . Supersonic and auxiliary grinding processes C/SiC ceramics base composite material, grinding force can be reduced about 20% , exterior surface roughness is ameliorable make an appointment with 30%[12] . With solid the hollow wheelhead of knot diamond is abrasive tool " in order to grind era getting " it is to have the stuff of good fragile difficult treatment such as pottery and porcelain, glass and composite material the effective treatment method that efficient nicety makes hole. On this foundation, use clip of supersonic and oscillatory knife handle to hold eletroplate or agglomeration diamond is hollow abrasive tool, the supersonic and auxiliary grinding that can realize material of these good fragile difficult treatment makes hole, if the graph is shown 15 times,its machine a principle. Use phone plating diamond is hollow wheelhead undertakes to carbon fiber composite material supersonic and auxiliary grinding and common grinding make Kong Jia be versed in, if the exit form appearance after treatment and appearance of tool surface form pursue 16 with the graph 17 are shown. The exit that can see by the graph supersonic and auxiliary grinding machines aperture does not have burr tool to wear away almost lesser, did not jam almost phenomenon [14] . Use metallic bond diamond hollow wheelhead undertakes radical of pottery and porcelain composite material is supersonic and auxiliary grinding makes hole, make Kong Xiangbi with common grinding, axial grinding force can be reduced about 60% , treatment efficiency can rise about 10% , and hole wall and quality of imports and exports are improved apparently [15] . In recent years, germany applies a respect to be in banner level in supersonic and auxiliary processing technique. Will supersonic technology and photograph of advanced machine tool technology join Hermann Sauer company of Germany and Deckel Maho company, development gave ULTRASonIC series supersonic and compound machining center, already waited for industrial domain to get applied in optical, medicine, semiconductor, car and aerospace. Processing technique of supersonic and auxiliary cut is supersonic and auxiliary cut processing technique is to be in processing technique of a kind of when supersonic vibration brings to bear on on tool of traditional cut treatment compound cutting. Use solid to written guarantee abrasive rotates will curium the technology uses a cut at the hard fragile data such as pottery and porcelain, optical glass and sapphirine to delimit piece, groove, cut off wait for treatment. Wait in glass of silicon and sapphirine brilliant circle, face plate delimit piece and get applied extensively in cut. Japanese DISCO company is in already had diamond thin curium a cut technology base on, developed use rotate cut piece processing technique of supersonic and auxiliary cut (graph 18) [16] . Use diamond to rotate cut piece when having supersonic and auxiliary cut, cut force is smaller, cut piece jam not easily, cutting tool life, can use tall feed speed to raise treatment effect to lead 3 times above, the cut that can use finer size piece the treatment quality with be obtained better and use smaller cut piece obtain narrower cut seam. When the processing technique of supersonic and auxiliary cut that uses the cut bit such as hard alloy dagger and wafer knife basically is used at composite material laid beforehand the cut out and issues makings and beehive construction composite material cut of dip fiber material and complex model face treatment. If cutting tool of facilities of the treatment principle of the technology of supersonic and auxiliary cut that Austrian GFM company develops, treatment, cut and effect of its cut composite material pursue 19 are shown [17] . Compare with average cut photograph, when adopting supersonic and auxiliary cut, cutting force is small, material is out of shape not easily, can raise cut precision; Can use high feed rate to improve treatment efficiency substantially; Can reduce the attrition force between cutting tool and workpiece, drop cut temperature, reduce cutting tool to wear away; The problem such as the knife is stuck in can solving average cut to machine. The last word is compound one of significant progress direction that processing technique is advanced processing technique, processing technique of supersonic and auxiliary cutting is to involve technical field wider, use the advanced and compound processing technique with wider range. Domestic and international the basic research of processing technique of supersonic to difficult treatment material auxiliary cutting and applied research result make clear, this kind of advanced and compound processing technique can reduce cutting force effectively, improve treatment quality and precision, decrease to cutting tool wears away and improve treatment efficiency, can use at carbon fiber composite material, grain to enhance composite material, pottery and porcelain to reach radical of pottery and porcelain already the treatment of the composite material structural member such as composite material, housing of porcelain dish of prism of usable also Yu Guangxue, contented, glass, illuminator is light quantify the hard fragile data such as structure and piston of pottery and porcelain the treatment of nice spare parts, wide applied perspective is had in the domain such as aerospace. To realize high quality of difficult treatment material, high accuracy, efficient treatment, the treatment of spare parts of material of difficult treatment of domain of contented and different application asks, current, processing technique of supersonic and auxiliary cutting passes the development experience that draws lessons from other processing technique, ceaseless Xiang Wei is refined, efficient change, nicety is changed, automation and intelligence are changed wait for direction to develop.
