Cutting tool technology is one of crucial technologies that implement treatment of high speed cutting, angle of the durability of cutting tool, geometry and its whole structure are the important way that cutting tool of high speed cutting studies. Material of cutting tool of high speed cutting asks to want to have taller hardness and wearability already below high temperature, should have higher intensity and tenacity again [1-2] . Accordingly, the formation that bits cuts in high speed cutting of process, cutting tool wear away mechanism and its temperature distributing, and the structural character of cutting tool will be the key in research of cutting tool of high speed cutting. Current, academic research and experiment method pay equal attention to in research of cutting tool of high speed cutting, academic research basically is centered in theory to build model and computation and finite yuan of imitate 2 respects, and finite yuan of imitate method is more intuitionistic, be close to true cutting course more, study cycle is shorter also, cost is inferior, because this got rapid development in recent years. In cutting tool research commonly used and finite yuan of software application is finite yuan the method undertakes emulation study to have cycle weak point, cost to cutting process low good point, because this wears away in cutting tool, wider and wider application received in cutting tool temperature distributings and cutting bits to form the research that waits for a problem. Current, commonly used finite yuan software has ABAQUS, DEFORM, MARC, ANSYS and ADVANTEDGE to wait. 1 ABAQUS ABAQUS can solve a large number of structures (stress / displacement) problem, OK still imitate is other a lot of problems of engineering field, heat up for example conduct, quality diffuses, earth of pyroelectricity coupling analysis, acoustics analysis, cliff is mechanical the analysis. ABAQUS has ABAQUS/Standard and ABAQUS/Explicit two advocate seek solution implement module [3] , still offerred special module to try to solve to certain and special problem, when building a model can parameter is changed, nonlinear analysis [4] is very perfect, but ABAQUS is to be based on assemble a thought to build finite of yuan of model, appear very trival for complex to building model. At the same time ABAQUS does not have fluid module, cannot make fluid calculation so. Current, in research of cutting tool of high speed cutting, ABAQUS can well imitate is banding cut bits and dentate the formation that cuts bits process, still can change cutting tool angle to come different cutting parameter is opposite imitate influence of the metabolic that cut bits. 2 Deform Deform is software of metallic figuration analysis, belong to special and finite yuan of software. Deform series software includes Deform-2D, Deform-3D, Deform-PC, Deform-PC Pro and Deform-HT (heat treatment) . Deform series is all the product is OK in metallic figuration analysis the figuration to cold, lukewarm, hot forge, heat conducts coupling and normalizing, anneal, quench, the process such as temper, cementite undertakes imitate studies. The Deform-2D that often uses at present is finite although yuan of analysis software can be compared conveniently imitate cutting process, but because processing of this kind of software is nonlinear the capability of the problem is not strong, cause imitate and experimental result to have bigger difference [5] . Current, in research of cutting tool of high speed cutting, deform basically uses simulation dentate cut what bits and helix shape cut bits to form field of temperature of process, cutting tool distributing and of the cutting tool below different cutting medium wear away the life of form and cutting tool. 3 MARC MSC.

Marc is a function all ready advanced nonlinear finite of yuan of software seek solution implement, can handle an analysis all sorts of linear and nonlinear structure [6] , like linear / nonlinear static force analysis, mode is analysed and destroy an analysis to wait. If the field problem to be not a structure includes convection, radiate, photograph to change of the complex and attrib border condition such as latent heat nonlinear conduct heat the temperature field of the problem, and shed field, electric field, magnetic field to also offer corresponding analysis to demand solution ability. The special need for contented and advanced user and undertake 2 times developing, MSC.

Marc provided environment of convenient open mode user [7] . Marc builds a model to compare difficulty to complex graph, additional, the version of Marc also has bigger change, right to it connective FORTRAN version also has a demand, have a lot of corrupt practice to abecedarian. Current, in research of cutting tool of high speed cutting, marc basically uses those who research field of cutting tool temperature to distributing. Software of 4 ANSYS ANSYS is analysis of structure of be in harmony, fluid, electric field, magnetic field, sound field at an organic whole large and general finite yuan of analysis software [8] , its software package is a multipurpose is finite program of yuan of law computer design, can use the issue such as field of the structure that seek solution, fluid, electric power, electromagnetism and collision. ANSYS each version is stabler, analyse in the structure, build model and process designing aspect very perfect, when solving groovy linear and coupling problem, have better sexual value to compare, but to nonlinear analytic respect returns existence blemish. Current, in research of cutting tool of high speed cutting, trends of the mode that ANSYS basically has with Yu Dao, instantaneous and statics of cutting tool system are analysed, also wear away with what study cutting tool at imitate mechanism. 5 ADVANTEDGE AdvantEdge FEM is a CAE software that is used at optimizing metallic cutting craft, apply to improve spare parts quality, raise material purify rate, lengthen cutting tool life to wait. Use AdvantEdge FEM to be able to decrease try cut a number, pass plan to be able to acquire optimized cutting parameter and cutting tool option quite. AdvantEdge FEM can analyse turning, milling (contain insert mill, corn mill) , bore, tap, bore hole, annulus chamfer, sawing, broaching the craft that wait, in 10nm above to feed the small cutting under 1 μ M supports 2D turning to emulate only at present, still can realize turning cutting tool and annulus chamfer cutting tool to wear away and stress of remains of milling of turning, 3D is emulated. The aftertreatment can get the result such as rate of cutting force, temperature, stress, meet an emergency [9] . Current, in research of cutting tool of high speed cutting, advantEdge basically is used at studying the distributinging situation of field of cutting tool temperature, OK still imitate turning cutting tool and wear out condition of annulus chamfer cutting tool. Finite yuan of law main application in cutting tool research 1 cut bits to form process imitate to thank Qing Yang [10] is used through large trade finite ABAQUS builds yuan of software cutting of orthogonality of H13 steel high speed is finite yuan of model, imitate banding cut bits and dentate the formation that cuts bits process, the key studied dentate cut the heat insulation inside bits to cut a phenomenon, through changing cutting tool angle to come different cutting parameter is opposite imitate influence of the metabolic that cut bits. Of cutting tool angle reduce promoted dentate the generation that cuts bits. NextpageBäker [11-15] uses ABAQUS software, use regular quadrangular reseau simulation what cutting of 2 dimension high speed cuts an area is dentate the figure that cuts bits; Studied cutting tool heat conducts influences of pair of the metabolic that cut bits again subsequently, heat conducts coefficient to increase, the extract that cut bits is reduced, cutting force adds, in cut belt place, the most remarkable to cutting bits to affect. Lu Shigong [16] is used finite yuan of ABAQUS software, undertook to process of cutting of orthogonality of high speed of Ti6Al4V titanium alloy finite yuan of emulation research, through finite yuan the analysis reached zigzag the formation that cuts bits mechanism, and test and verify finite yuan emulate about titanium alloy zigzag cut bits to form mechanism to be thermoplastic lose firm verdict. Özel [17-18] is based on DEFORM-2D software, use not the imitate of WC cutting tool of coating the cutting process of the P20 mould steel of HRC30, the appearance cutting bits of 2-D submits dentate form of the standard, the appearance cutting bits of 3-D submits helix form. 2 cutting tool wear away the research Zhao Wei of mechanism [19] wears away through high speed attrition experiment, cutting treatment test, cutting tool wears away experiment and finite yuan of experiment such as imitate and theory, analysed cutting tool of the hard alloy below nitrogen and air medium when alloy of titanium of high speed cutting basically wear away form and cutting tool life; Announced to the brittleness of cutting tool of the hard alloy when alloy of titanium of cutting of the high speed below nitrogen and air medium is destroyed and wear away mechanism and the main factor that affect life of hard alloy cutting tool. Li Yimin [20] application is finite yuan of software Deform-2D, the orthogonal cutting that to aviation Ti6Al4V of the alloy that use titanium undertook differring cooling lubricating the condition falls is finite yuan of imitate, the lubricant intention that indicates cutting medium as a result is right of face of the knife before cutting tool diffuse wear rate has bigger effect, and the cooling action of cutting medium spreads to face of the knife before cutting tool wear rate does not have distinct effect. Li Longtao [21] application is large and finite yuan of software ANSYS is right metallic cutting process undertook numeric imitate, face of the knife before was being analysed and the attrition condition that cut bits. The position that through be opposite the greatest equivalent stress and meet an emergency produce and its change are analysed, reach face of the knife after cutting tool wears away the most serious conclusion. The imitate Du Meijing that temperature of the cutting tool in process of cutting of 3 high speed distributings [22] is used finite imitate of yuan of analytic software Deform the process of high speed cutting of AISI-1045 steel, the allocation of the distributinging case that got field of cutting tool temperature and heat in metal cutting circumstance, undertook an analysis to the thermal stress of cutting tool. Zhao Yunfeng [23] uses AdvantEdge software simulation the milling process of aluminium alloy A12024, the temperature that analyses the workpiece in getting milling is machined and cutting tool to go up distributings the rule. The highest temperature on cutting tool distributings advanced knife face and area of the contact that cut bits; The temperature of cutting tool of temperature prep above that cuts bits about 25 ℃ . The distributinging rule of temperature of the cutting in this and process of high speed treatment and cut bits to take away major caloric be identical of actual condition photograph. Yang Zhenchao [24] uses professional metal cutting treatment is finite yuan of software AdvantEdge, undertook to process of milling of high speed of TC4 titanium alloy 2 dimension imitate is emulated, obtained milling rate to be opposite the influence rule of temperature of cutting of face of knife of cutting tool around. Basin Hong Min [25] is used finite yuan of software MSC.

Marc was built comfortable the meet an emergency of 2 dimension plane at strong voice cutting is finite yuan of model, emulation operation got cutting ply is 0.

1mm, the temperature that arris and round cutting tool and workpiece pour to go up when cutting speed is 120m/min distributings (graph 1) , from emulation result in contrasting, can reaching is caloric basically collects an area near blade of cutting of 2 kinds of cutting, quantity of heat basically originates the plasticity of material is out of shape and cutting tool and the attrition that cut face of the knife after bits, cutting tool and work. The highest cutting temperature that what differ is cutting tool of circular arc blade is before blade area, and the highest cutting temperature of cutting tool pouring arris is cutting bits shedding classics the first be out of shape after the area, the distributinging case of temperature of this kind of cutting is to be helpful for cutting tool life and already machined exterior integrality. In cutting tool and area of the contact that cut bits, the temperature on cutting tool slightly under the temperature that cuts bits. The structural character of the cutting tool in process of cutting of 4 high speed analyses Du Xiaodong [26] used UG to build the hypostatic model that establishs milling cutter, reintroduce ANSYS was built establish milling cutter accordingly finite yuan of model, before be being extracted next 5 rank natural frequency, undertook establishing milling cutter finite the mode analysis of yuan of model; Use rank the fundamental frequency that jumps response methodological plan cipher out to establish milling cutter and corresponding damp coefficient, undertook establishing milling cutter finite the analysis of transient state motivation of yuan of model. When high speed cutting, because the rotate speed of cutting tool system is very high, leave what mental efforts causes cutting tool system to be out of shape, affect the life of cutting tool thereby, thank dawn to wait [27] applied ANSYS software to undertake to its statics is analysed, put forward to improve the technical program of dynamic balancing of cutting tool system. Last word what the article introduced middling of cutting tool of high speed cutting to use is finite yuan of software, right at present achievement of cutting process emulation acquired undertook treatise. Study the result makes clear, application is finite yuan of method is OK imitate is banding cut bits, dentate cut what bits and helix shape cut bits to fashion a process, research cutting parameter and cutting tool angle are affected to cutting bits metabolic, be opposite from this the formation of cutting mechanism undertakes an analysis. In the meantime, can distributing to the temperature of cutting area, the damaged of cutting tool and wear process undertake imitate, analyse the main influencing factor of above process. Additional, still can reach the cutting dosage integration analysis that undertakes structural character go up to composition of the geometrical angle of cutting cutting tool, material. Above research can be mixed to material of cutting tool of high speed cutting structural design offers important theory to prop up. CNC Milling CNC Machining
