The Cimatron software product of Cimatron company is a compositive CAD/CAM product, in unified systematic environment falls, use unified database, the user can complete the structural design of the product, hardware design, output designs blueprint, can undertake according to the three-dimensional model of the spare parts handiwork or automatic mould distribute a model, undertake to protruding, sunken model automatic NC is machined again, output the NC code of treatment. Because Cimatron rises in sale year after year of China, cimatron company decision is in Cimatron Beijing delegate (held water 1998) promotion is the subsidiary that manages independently- - think of the United States to achieve (Beijing) limited company of science and technology. While CimatronChina is in charge of support of the market, sale, technology and after service job, still be for each agential SGV, Unigenius, Semidome in support of the market inside respective area, sale, technology and after service job provide corresponding support. Make the progress of the industry as the mould, raised new requirement to CAD/CAM system, cimatron is a current CAD/CAM system not only today, and provided new tool market in the light of mould industry -- Quick series product (contrast of model of cent of ｝ of QuickConcept of the fast product ｛ that browse, fast mould and the ｝ of QuickSplit of fast definition ｛ that unplug modular angle analysis reachs cent range, fast products plan analyses ｛ QuickCompare ｝ . Be in China today the user of Cimatron group also be in quick amplification, apply extensively already at each industries, become current pattern design and make accepted first selection product, the Cimatron that the well-known company of a lot of China uses. These users include: Chun Lan machinery creates limited company, hai Ermo has limited company, center of Ao Kema mould, beautiful mould makes machinery of limited company, new division create limited company, henan new rural area flies to China of group of the wind when pattern production limited company, Jinan rides mould of group, Jinan small duck gently to make limited company, Shandong, Luoyang newly plant of car of group of the first tractor, Changchun - Guokai mould is made and equipment safeguards limited company, Shenyang to fly. Characteristic of technology of WINDOWS online guidance as the world's famous CAD/CAM system, cimatron is in the world's accepted lead position all the time in respect of numerical control process designing, basically reflect in the following respects: One, the treatment that is based on knowledge: This is the treatment core characteristic of the buy inside Cimatron system, after this characteristic assured to choose to machine object and appropriate treatment method and its craft parameter in the user, undertake an analysis to the state of treatment, adjust cutter track contrail reasonably, make treatment result more reasonable, safer, more efficient; 2, the treatment that is based on knowledge of semifinished product remain; As this technology achieve manufacturer formerly, cimatron makes this one technology more perfect with rich. The initiative semifinished product that knowledge of semifinished product remain is the correspondence of definition of semifinished product appearance that shows user basis is machined actually (can define regular semifinished product namely, wait like honest stuff, round makings, also can define be based on model of spare parts theory to slant of the visible form of buy cast semifinished product) , in machining a process, the in the spare parts theoretical model after the system knows to be machined last momently apparently appearance of the rest semifinished product and semifinished product characteristic, combine specific treatment method to do to machining orbit thereby a series of treatment optimizes: Sky of automatic place to go walks along knife A, implementation not to have empty treatment taking a knife: Machining a spare parts especially is to cast when coming out, this characteristic more make the cutter track contrail of generation did not go for nothing, and the contrail of treatment and efficiency are best; Because we are OK,define according to model of spare parts theory definition according to casting the circumstance of semifinished product surface of edge spare parts is equidistant slant of buy cast semifinished product, and Cimatron system knows to be in currently constantly the semifinished product condition of surface of model of spare parts theory, when undertaking waiting for tall rough machining, the system can undertake optimizing computation according to the semifinished product condition of current part surface, produce treatment contrail in the place of hairiness base only, avoid to appear undertaking waiting to leave high like the system that was not based on knowledge of semifinished product remain thick when the condition that occurrence sky cuts. The B, relative safety that achieves security carries quickly knife, move knife: To improve the efficiency of treatment, cimatron support carries relatively of knife position carry relatively knife method, opposite height can locate prep above raises the height with proper place, be like 2mm, 5mm, in move the comparison that cutting tool and semifinished product of spare parts remain have in the process of the knife, the safe height that uses an user to be defined at first below the situation that produces interference undertakes moving knife; The C, interference that realizes the cutting tool on real significance and its collet checks: (A) true interference examination: The CAM system that examines without the true interference that is based on knowledge of semifinished product remain is to use the theoretical model of cutting tool and spare parts to undertake relative, cause the collision that machines actually easily, and the CAM system of the treatment that uses knowledge of semifinished product remain is the form of rudimental semifinished product that processes actually last time with cutting tool and spare parts undertake comparative, make collision examination more perfect, safer more reasonable also; Automatic and statified treatment (B) use equipment automatically to choose treatment of cutting tool successive: The user can appoint equipment to pick list of treatment cutting tool, in treatment in the first knife especially deep gorge and gully produce interference when, the system machines the area that can machine with current cutting tool only, and the area that uses have a smattering of a subject to be able to machine it then, another knife machines reelection the area that it can machine, finish till treatment till. On program output the user can choose to output the program of different share respectively by cutting tool, also can change a knife automatically in the program and output with a program; The D, analysis that realizes the cutting tool load on whole sense and rate adjust optimize: (A) be based on cutting bulk: The treatment that is based on knowledge of semifinished product remain makes a system can true according to cutting tool current effective treatment is measured -- treatment bulk -- undertake load is analysed, is not a basis Dao Kuan has speculation, increased cutting tool load to analyse optimized scientific sex and accuracy; (B) be based on cutting angle: Cimatron can undertake according to semifinished product state rate is adjusted not only optimize, OK still undertake optimizing according to the athletic angle of surface of spare parts of cutting tool edge - the point of view that cuts material is older rate is minorrer, the point of view that cuts a material is older rate is older; (C) overload is statified treatment: Cimatron load analysis and optimize a technology to still choose in the circumstance with overmuch surplus statified the processing means of cutting, divide a treatment automatically to overmuch semifinished product of remain to finish namely; Surplus of rudimental semifinished product 3, chase deep processing technique to machine especially difficult part: In be machined actually we can encounter the part with a lot of more difficult deepness, machine the effect to achieve first-rate, to the treatment of these spare partses Cimatron allows an user as deepness increasing gradually the length that increases cutting tool, to differring the cutting tool of length can limit the deepness scope that its machine, the cutting tool that avoided to use onefold length thereby completes whole treatment and process error as a result of what place of cutting tool spring back causes, cause treatment the outcome is not ideal; 4, direct treatment result desired result: Support machines the comparison of result semifinished product and theoretical model finally, the fundamental condition after making process designing personnel knows current institute program is machined actually in the spare parts quickly, help process designing personnel undertake process designing thereby decision-making, know to need to have the case of further treatment namely, undertake farther process designing. 5, the automation process designing that is based on craft feature; Regard the Cimatron that uses this technology the earliest as the company, make the application of this technology more agile. This technology is OK rise the typical process of the factory and parameter memory form treatment mode, when should new part can use same treatment method to undertake machining, technical personnel need not weave from the beginning treatment craft, let a system realize automatic process designing according to the treatment mode of technical personnel make choice of. This technology has the following distinguishing feature: (A) craft mode need not particularly custom-built, want to think process of a certain treatment has durability only, the user can be put into treatment mode; (B) the parameter dependency that machines the craft parameter watch of mode to have craft parameter, the modification of parameter of a few craft can make other and relevant craft parameter is revised subsequently, when be like an user to should use a cutting tool, cut wait greatly to be able to be revised subsequently with quantity of side direction penetration of a cutting tool, what this increased craft parameter to define not only is quick with convenient sex, also increased the adaptability of craft mode; (C) the identifying that realizes geometrical information with a variety of methods and extraction. The treatment of a spare parts includes many treatment measure, the distinct possibility in machining measure has some of measure to involve the relevant share of the spare parts only, ask craft mode can identify the corresponding geometry information related to some treatment measure automatically at this moment. Cimatron can allow an user to appoint a variety of methods to finish, the mechanism that if be based on color,identifies, be based on a line model mechanism, the union of the mechanism that is based on geometrical gather definition and this 3 kinds of mechanisms is used. (D) a large number of actual conditions that because these craft were united in wedlock to use unit product characteristic, process designing characteristic and actual equipment to wait,machine a state, make these craft more reasonable, more chastening, safer, more efficient; These typical craft can form the knowledge base of process designing, newcome technology personnel still can be used very quickly already some craft libraries undertake actual process designing works. Intelligent clear root machines 6, the unifinication treatment that is based on slope to analyse a technology is politic: (A) slope analyses a technology: Slope analysis technology is produce demand as increasingly pressing treatment, to machine program the work out asks more more automation, rapid and a of generation technique that processes a characteristic in the light of milling, this technology is to point to in the program in building a course, can have analysis and distinction to the actual figure characteristic of the spare parts, finish specific figure to use the program computation technology of specific treatment method thereby. (B) unifinication analyses treatment: Cimatron is one of CAM systems that use slope the earliest to analyse a technology, cimatron had come true to analyse the primary level that searchs a technology to use appropriate treatment method to undertake this location is machined then automatically from alone feature area today, the unifinication analysis that development went to to face whole treatment object and treatment -- the identifying that uses a function to be able to undertake differring machining area and characteristic analysis, next the different area of integrated and whole spare parts, use optimization, the quickest way uses different treatment strategy to different area, at the same time guarantee against machines cutter track of the first-rate between area together join and optimize, assure first-rate surface quality. (C) use give a demonstration: The clear root that as above pursues is machined, the system can analyse a what area automatically is horizontal area, what area is vertical section, edge rough sketch can be used in horizontal area equidistant treatment, parallel cutting treatment or round treatment means, the corner that uses contour line to machine means to realize vertical section to vertical section clears; Be like left the picture place that two lines draw a frame round shows is shown, the method that the system is analysing to slope is being used when the spare parts has precision work can is opposite whole spare parts or the treatment area that define by outline undertake an analysis, to different treatment area uses more appropriate treatment method -- use contour line precision work to vertical section, use the method that cuts along exterior annulus to have precision work to gently area, the integral finish machining that realized whole spare parts or partial section namely inside function of treatment of a WCUT thereby, assured best treatment at the same time efficiency, acquire best exterior quality. 7, optimal beforehand is optimized, reduce after the event to perfect ― the distinctive treatment that Cimatron is aimed at mould industry is politic: Much axis spare parts is machined (A) optimal beforehand optimizes a technology is to show the process designing process in the mould is medium, the system offerred the rich, technology that has specific aim, make the treatment of each pace is next treatment makes good first-rate preparation, because upside machines a result to pay no attention to,decrease want to cause process designing staff increases when undertaking machining process designing further the consideration to machining a condition, also affect the result of treatment at the same time; (B) after the event is perfected is to show in current treatment condition bad situation falls, the user is used a few additional process designing set or optimize a method, avoid the effect of current and bad situation, if avoid cutting tool overload,wait. (C) a lot of process designing technologies in Cimatron system gave sufficient consideration to such requirement. The WCUT of the Cimatron that is famous in the whole world for instance is rough machining of a collect, semifinishing machining and finish machining the treatment method at an organic whole, when using this method to undertake rough machining, the system can be in the share that the two overmuch surplus that gently now area sends between the layer have undesirable effect to finish machining to these then undertakes the rework between automatic layer (use the tall method such as successive, law of edge face smooth knife) , make be in before finish machining thereby the surplus of spare parts surface as far as possible even, avoid overload of local cutting tool to produce collapse knife, also make when the finish machining in the future won't because be not gotten with it is not quite good that low speed cutting causes exterior quality, for next finish machining has made sufficient preparation. If be when finish machining,to because surplus all is opposite,avoid cutting tool produces undesirable effect, be like cutting tool overload, the analysis of cutting tool load after collecting act and optimize, although can avoid the happening of the accident or the exterior quality that affect a part, but not be first-rate processing method. Because if be in,the surface of the spare parts is the place of large surplus everywhere, want to undertake low speed cutting everywhere, affected treatment efficiency not only, and the exterior quality of treatment also can be affected, special in the application that processes in high speed milling more abstain from the occurrence of this kind of circumstance, high speed treatment also did not become high speed milling to machine. Side direction of screw type of high speed mill moves 8, rich, perfect, safety and efficient high speed milling machine the function: Can use NURBS interpolation output to support high speed milling below any forms; Ability of advanced high speed milling: Helix feed, round horn takes a knife, between the layer, the circular arc between travel makes even knife and cycloidal type treatment knife contrail is more smooth in order to get used to high speed milling; Feed number rate is optimized on the foundation of knowledge of rudimental semifinished product; Mix through self-adjusting feed speed automatic and statified will ensure needle of constant cutting tool load, to high speed milling the circular arc between implementation travel connects knife and screw type to move the knife is waited a moment. Milling of Cimatron high speed had received wide application in home, if mould of sea Er group makes limited company, Chun Lan,machinery creates limited company of limited company, Xi'an aviation engine - the lamina that install peaceful is waited a moment. 9, the collateral process designing that supports urgent task machines mode; The mould makes an industry facing urgent task sometimes, the implementation of process designing personnel that how distributings a task to differ at this moment is machined in coordination crucial. Because Cimatron has,be based on treatment of knowledge of semifinished product remain, and the user can machine some memory of semifinished product of process designing result rises deal out is other process designing personnel, personnel of so other process designing is OK the different area that the spare parts is aimed at on the foundation here undertakes corresponding finish machining process designing and careful treatment process designing; Combinative PDM can make this job more convenient; 10, have constantly the system of numerical control process designing of decision-making support: Cimatron is the likelihood that encounters in process designing of user numerical control the problem provided auxiliary analysis tool, if the spare parts before treatment can machine the examination of area (the area that whether the examination pours wine cup again and cannot machine) , the part is the smallest the size of curvature radius and place area, of current remain semifinished product look carefully at immediately (it is OK that the user need not emulate imitate the treatment result of directive and current part how, and the user can undertake dynamic analyse segments analyse) , surplus analyses desired result to wait a moment. Information of PDM technology craft is in charge of 11, the information that the PDM system that undertakes for the center with the project technical information manages is platform is shared with synergic environment; The PDM system of Cimatron, with the client / server mode provided the applied platform with a compositive information for technical personnel, make the plan of the task and plan management become a possibility, came true to be the centralized management of technical information of the center with the project, offerred effective assurance for technical information safety. In information management, can undertake project management, documentation management, task management, working flow management and working schedule manage not only, all other documentation related to the technology can get administrative, wait like Word, Excel, PowerPoint, stencil of code of mould model, treatment, technology and state of machine tool equipment also can achieve unifinication administration. The treatment characteristic of Cimatron makes Cimatron has become current CNC Machining, especially one of first selection software that the mould machines, the processing technique of Cimatron still is continueing, apace develops, and the position that holds the world to precede.
