At have got a flood of application such as aviation industry, car industry etc. realm. Because producing the physically strong need, domestic and international all the logarithms controls to weave the distance technique preceded the extensive research, and obtained the plenteous result. The underneath controls to weave for the logarithms distance and its developments make the some introduction.1.1 numerical controls programming basic conceptNumber control to weave distance is from spare parts diagram paper to acquire the number control the whole process that processes the procedure. It of the main mission is a calculation to process to walk the knife in the knife orders. (Cutter location point brief name the CL orders)The knife orders to take generally to have for the knife the stalk line has with knife to hand over to order superficially, many stalks processes the inside to still want to out the knife stalk deal.1.2 numerical controls programming technology development introductionControl the procedure establishment problem,50s that process the inside for the sake of the solution number, the MIT designed a kind of used for exclusively the machine spare parts number control the language that process the procedure establishment, calling the APT.( Automatically Programmed Tool)Afterward, the APT is several through the development, becoming such as the APTII, APTIII( stereoscopic slice the use), APT( the calculate way improves, increasing to much sit to mark the curved face process to weave the distance function), APTAC( Advanced contouring)( the increment slices the database management system) with advanced version in etc. in APT/ SS( Sculptured Surface)( the increment carves the curved face processes to weave the distance function).Adoption APT language establishment the number controls the procedure has procedure Chines, walking vivid etc. in control in knife advantage, make number controlled to process to weave the distance from face to the machine bed instruction of edit collected materials the language class, rises to face to several why chemical element. APT still contain many inconvenient places: The adoption language defines the spare parts several why shape, and is hard to describe complicated and several why shape, lack the several keeping the view why; Is in need of to have to exercise to the spare parts shape, knife the track keep the view sketch show with the knife verification means of having the track; It is hard to link with the system of CAPP effectively with the database of CAD; Not easy automation working up highly, gather turn.Weakness, 1978 that aim at the language of APT, France reaches the airplane company starts developing gathering three designs, analysis; the NC processes the system that integral whole turn, calling for CATIA. Appear the elephant EUCLID, UGII, INTERGRAPH, Pro/ Engineering, Master CAM and NPU very quickly later on/ GNCP etc. system, these systems resolved all and effectively several why the shape, spare parts is several why the manifestation of the shape, hand over to design with each other, the modification and knife has the track born, walk the knife process imitate true manifestation, verification etc. problem, pushed the CAD to turn to integral whole the direction development with CAM.80s, in CAD/ the integral whole of CAM turning the foundation of the concept, became gradually the calculator gather manufacturing system( CIMS) and proceed together the concept of the engineering( CE).Current, for the sake of the demand of the orientation CIMS and CE development, the number control to weave the distance system face to gather turn to turn the direction development with intelligence.In the aspects of gathering turning, then develop to match the standard parameter in STEP (Standard for the Exchange of Product Model Data) turn characteristic shape system is work that lord, have proceeded now the large quantity have results to show the effect, is a domestic and international developing a little bit hot; In the aspects of intelligence turning, work just start, still treat we work hard.2. NC cutting tool path production method research development present situation2.1 based on spot, line, surface and body NC knife axle production methodThe number controls the core work that weave the distance is a born knife to have the track, then will its long-lost the knife orders, through post pose to handle creation the number controls to process the procedure. The underneath has for the knife the track creation method makes the some introduction.The technique of CAD from two painting start, experience three line frame, curved faces develop the stage with the entity shape, the till now parameter turns the characteristic shape. At two painting with three stage in frame in line, number control to process main then order, line is drive the object, if the bore processes, the outline processes, the flat surface district processes etc. This kind of process the levels that request operate personnel higher, hand over with each other complicated. Develop the stage with the entity shape at the curved face; appear according to the entity processes. The entity processes of process the object is an entity (general mix with BREP for the CSG mean of), it from some basic vegetable through gathers to carry to calculate (and, hands over, differs to carry to calculate) but get. The entity processes and can not only used for the spare parts process to process with the half , the big area slices the drops the amount of remaining, increasing to process the efficiency, but also can used for according to the number of the characteristic controls the research that weave the distance system?The entity processes to have generally the entity outline process to process with the entity district two kinds of. The entity processes of realizes method as the layer slice the method( SLICE), then use a horizontal plane slice to is processed entity, then to get of hand over line creation etc. be apart from the line conduct and actions walks knife track. This text needs from the system the angle sets out, realizing in ACIS is several why shape terrace this kind of according to order, the line, controls to process with the number of the entity.The parameter turns the characteristic shape there has been certainly of the development is period, but according to the knife of the characteristic just have the research of the born method in track just start. The characteristic processes to make number controlled to weave the distance the personnel not at are low level and several to those why information (such as: order, line, entity) proceed the operation, but change is direct to match the habitual characteristic in technical personnel in engineering proceed number control to weave the distance, increases consumedly plait distance efficiency.The W.R.Mail give the born sub- system in a the code of NC for alley basing on the characteristic with A.J.Mcleod in their research, the work principle of this system is: Each one of the spare parts processes the process can see to shape characteristic a total for proceeding processing that constitute that spare parts. Completed namely after processing respectively to whole shape characteristic or shape characteristic sets so the spare parts process. But the code of NC between each shape characteristic and shape characteristic set is automatic and born. The system of the current development is applicable to only a spare parts process.2.2 based on characteristic NC knife axle production methodThe Leaned Chang developed a kind of convex and free curved face in automatic creation in method characteristic knife that use the system that conjecture boundary have track. The work principle of this system is: In convex and free curved face into a minimum rectangle piece, like this convex and free curved face characteristic were converted a cave characteristic. Minimum rectangle a kind of indirect product for with end product model merging constituting drive calling conjecture model. The knife has the born method of the track is divided into three steps complete:(1), slice many characteristic;(2), slice the free curved face in characteristic;(3), slice to hand over the characteristic mutually.The JongYunJung studied according to the characteristic slices not the knife has the born problem in track. The article processes according to characteristic the track is divided into the outline processes to process with the inside district two type, and defined these two types process of slices the direction, pass the decrease slice the knife has the track attains the whole the excellent turning the purpose that knife have track. The article aims at a few and basic characteristic (the bore, inside is cave, step, slot) primarily, discussing the typical model of these basic characteristics walk the knife path, knife has the choice with process in proper order etc., and pass the IP (Inter Programming) technique avoid the repetition walks knife, with excellent turn to slice not the knife have the track. Moreover, the JongYunJong returned to study in him the doctoral dissertation of the 1991 the manufacturing characteristic withdraw with the knife that according to the characteristic has and the knife has the path.The foundation that characteristic process is an entity to process also can think certainly that is a more deluxe entity to process. But the characteristic processes the different from entity processes, the entity processes it the localization of the oneself. The characteristic processes different from the entity processes to have primarily below what time:Speak from the concept, characteristic is operation habit that function to constitute the spare parts main factor, match the engineering the technical personnel, for engineering technical personnel be familiar with; The entity is a low layer several why object, carries to calculate through a series of cloth but get a several why, do not take any function language righteousness information; The entity processes to usually process to the an of whole spare parts( entity).But in reality a spare parts uses only probably not too on processing the knife is an over, usually process through , the half processes, the processes a series of work in etc. step, the different part in spare parts has with the different knife generally the proceeding processes; Sometimes a spare parts since use the car .The for this reason entity processes primarily the of using for the spare parts processes and the half processes. But the characteristic processes then from resolved the above problem essentially; the characteristic processes to have more intelligences. Can rule for the particular characteristic some several kinds fix of process the method, especially those are already the characteristic that rule in the STEP standard is also such. If we all established to all standards characteristic to process the method particularly, so to those from standard characteristic enough of the spare parts processed its convenient and then caned imagine. If the system of CAPP can provide the homologous craft characteristic, so the system of NCP can reduce to hand over consumedly to input with each other, have more intelligences. But it is what cant realize that these entities process;The characteristic processes to benefit to realize to gather completely from CAD, CAPP, NCP and the system of CNC, realize the double of the information face the fluxion, for CIMS is to proceed together the engineering( CE) lay the good foundation; But the entity processes incapable to these for dint of.2.3 active duty several main CAD/CAM in system NC knife axle production method analysis2.3.1 Active duty CAM constitution and main functionThe current mature the system of CAM is main to realizes with two kinds of forms the CAD/ the system of CAM gathers: The CAD/ the system of CAM that integral whole turn( such as: UGII, Euclid, Pro/ ENGINEER etc.) with opposite and independent the system of CAM( such as: Master cam, etc. of Surf cam).The former including a data for unifying format direct from the system of CAD obtains the product several why model, and then pass the neutral document primarily to obtain the product from the other the system of CAD several why model. However, regardless is which kind of forms of the system of CAM, all be constituted by five molds piece, then hand over with each other the craft parameter inputs the mold piece, knife has the born mold in track piece, knife has the track edits mold piece, three process the development imitates true mold piece with post pose to handle mold piece. The underneath processes for the some a NC for of CAD/ the system of CAM only the method precedes the discussion. 2.3.2 UGII processing method analysisThink generally that the UGII is commerce inside best; have most the representative number control the software. Its have most the characteristics is a mighty knife in its function to have the born method in track. Including the car， line incises etc. To process the method perfectly. Among them has primarily below function:Pointto Point: Completing every kind of bore processes;Panar Mill: Flat surface .Include the single slicing to line, the double slices to line, the wreath slices and the outline processes etc.;Fixed Contour: Fix many stalks casts shadow to process. Have with the projection method control knife in the single last or several the ambulation on the curved face in a curved face, control the knife have the ambulatory being an already born knife to have the track, a series order or a suite line;Variable Contour: The variable stalk casts shadow to process;Parameter line: Waiting the parameter line processes. Can continue to process to single pieces curved face or many pieces curved faces;Zip Zap Surface: Cutting processes;Rough to Depth: The processes. Process to specify the depth the semi-finished product;Cavity Mill: Many classes depth type processes. Be applicable to the convex mold specially to process with the of the cave mold;Sequential Surface: The curved face hands over to process. According to the spare parts, lead to move with the way of thinking that check the ambulation that have the control to provide the biggest degree to knife.The EDSU biographic still includes the function of a flood of other aspect, here different on enumerating.2.3.3 STRATA processing method analysisIt provides two kinds of plaits distance development environment for the customer, namely NC order the language connects operates the C with NC+ a key. It can support three stalks, the car incises with the line the NC processes, combining cans support the line frame, curved face to is several to set up the mold why with the entity. Its knife of NC has the born method in track is to bases on the entity model. The STRATA bases on the knife of NC of the entity has the track born provides of process the method include: Profile Towpath: The outline processes; AreaClearToolpath:The flat surface district processes; SolidProfileToolpath:The entity outline processes; Solid Area Clear Tool path: The entity flat surface district processes; Solid Face Tool Path: The entity surface processes; Solid Slice Tool Path: The entity cuts the flat surface processes;Languag abased Towpath: According to the phonetic knife has the track born.Other CAD/ the software of CAM, such as Euclid, Cimarron, CV, the etc. of CATIA the function of NC is each has his merits, but its basic contents is alike with minor differences, having no the innate character differentiation.2.4 active duty CAM system knife axle production method main questionsAccording to traditional CAD/ the system of CAM with the system of CNC work method, the system of CAM with direct or indirectly (pass the neutral document) of way obtain the product several from the system of CAD why data model. The system of CAM with three are several why a form for, or entity is driving object, bony processing knife having track, and with knife having fixed position document through postpone to handle, provide with the code of NC form to the CNC machine bed, in the aspects of exists in the movement process between whole CAD/ CAM and the system of CNC below severally of problem:The CAM system a low layer for can from the system of CAD obtaining product is several why information, cant catch the product automatically several why shape information with product high functions with language righteousness information. Therefore, whole the process of CAM must manufacturing in rich in experience the engineer participates the bottom, passing the sketch hand over to come to complete with each other. Such as: Making the engineer must choose to process the object (order, line, or entity) and control the term (pack to clip, interfere with with hits etc.), knife have, processes the parameter.( slice the direction and slice deep, enter to the deal, enter to wait the speed)The automation degree of whole system is lower.In born knife in the system of CAM had track, the same also include the low layer only several why information (straight line with arc of several position the information why), and a little amount process control information.( if enter to turn the rate, principal axis soon, change the knife etc.)Therefore, the system of CNC of the downstream since cant obtain the design request (such as business trip, surface clean an etc.) of the higher layer, also cant be had something to do with born knife having track to process the craft parameter.Mold product data disunity, each mold piece is opposite and independent. For example the knife has to position the document only record the knife have the track but do not record to process the craft parameter homogonously, three the development really imitate only record the knife have the track interferes with with hits, but do not record with its the occurrence interferes with with hits of process the object and process the craft parameter relatedly.The system of CAM is an independent system. The system of CAD has no united product data model with CAM system, rising in integral whole turn of gather CAD/ CAM system even, the information shares too just one-way with single. The system of CAM cant comprehend well with make use of the system of CAD all information concerning product, is a characteristic to have something to do with processing information particularly, the same the system of CAD also cant obtain the system of CAM produces of process the data information. This give to proceed together the engineering puts bring into practice to trap. 3. Computer simulation concept and applicationSeeing from the angle of the engineering, rallying imitate is to pass to study to the experiment of the system model a there has been of or the system that design the inside. The dynamic object of the analysis complicacy, imitate is really period that a kind of valid method, can reduce the risk, shorten the design with the manufacturing, combine economy investment. The calculator really imitate is to ask for help the calculator, make use of the system model to start experiment the investigative process to the
