UG 4.0 software piles up the application in label NC process designing in mould word

0 software are the inevitable first selection that undertakes NC process designing. With the word code label is exemple, pass craft analysis, three-dimensional to its the comparison that builds model, follow-up CNC Machining and other software, proved UG4.

The 0 wide application in manufacturing industry. UG4.

The 0 calculation that reduced engineers to go up in the program greatly are measured, the workload that also reduced machine tool handlers at the same time and improved manufacturing efficiency, won cost and time for the enterprise. 1, the three-dimensional parameter that introductive UG software is collect CAD/CAM/CAE/PLM unifinication converts software, provided a products plan environment that is based on a process, make the product develops what realized data truly to treatment from the design to not have seam compositive, the products plan that optimized an enterprise thereby and make. This software has powerful substance not only modelling, curved surface modelling, fictitious assemble and produce project attempt to wait for design function; And, can undertake in designing a process finite yuan of analysis, orgnaization motion analysis, kinetic analysis is mixed emulation imitate, raise the dependability of the design; In the meantime, can generate numerical control code directly with built three-dimensional model, use at the treatment of the product, handle a program to support machine tools of a variety of type numerical control ever since. The UG/OPen GRIP of 2 development language that additionally it offers, UG/open API learns easily simply, implementation function is much, facilitating user develops special CAD system. The industrial domain such as sky of wide application Yu Hang, spaceflight, car, shipbuilding, current mechanism and electron. 2, the requirement of NC process designing that word code marks and the analysis that machine craft: 2.

The product that 1 company produces is forging, as a result of client product but requirement of date from sex, in product surface need produces lot number label: (1) 606RA123: 606 delegates were produced in June 2006, r delegate is right, a is represented June the first batch, date of furnace of 123 delegates material; (2) font is the Arial that Windows system takes oneself, font height is 6mm; (3) is protruding word on forging product, steel is sunken word on the mould character, the black lead electrode that marks namely is protruding word; (Because 4) produces lot number to change frequent, best parameter changes lot number of the text in CAD (after changing text lot number, the heavy new unripe course that become a knife can) ; (5) because line of the products is more, word code has the different case such as planar, cant, curved surface (phase of curved surface treatment is relatively more complex than other, can solve curved surface treatment so, other problem with respect to be readily solved) . Word code deepness is not close also identical (the deepness that does not consider carve characters on a seal when process designing! When treatment by hold machine person the hand of word code deepness that differs according to different product is moved can) ; 2.

2 ask in the light of afore-mentioned process designing and combine company actual condition, with curved surface treatment is the exemple is preliminary make its machine craft: (1) considers to machine an object to be black lead electrode, the curved surface of ball knife mill that chooses 5mm (electrode piece machines necessary step first, treatment efficiency is tall, break a knife not easily) ; Because font height is 6mm,refer to graph 8 (2) , choose cutting tool diameter for 0.

The knife of carve characters on a seal of 8mm machines the process designing of; 3, of all kinds software to reach its to choose quite: The collect on the market the it may be said of of all kinds software of CAD /CAM unifinication is to emerge in endlessly, let a hundred flowers blossom. Such as: CATIA, UG, Pro/E, MASTERCAM, SURFCAM is waited a moment, in the light of at present the application on the market compares much software MASTERCAM, SURFCAM, UG, Pro/E generally 4 kinds of commonly used software pile up label process designing to do to the word preliminary quite: 3.

1MASTERCAM X: The CAD /CAM software that company of American CNC SoftWare INC makes, machine a function formidably with its especially famed at the world, treatment operation interface is straightaway, efficiency of process designing treatment is remarkable. But in the light of process designing of label of code of this mould word character, process designing operation is agile, yi Xueyi is used, parameter of label text dispute is changed, lot number is updated immediately not easy, bring about process designing efficiency not tall. Refer to a graph 1, graph label of cant of 2 MASTERCAM of plan of emulation treatment of label of plane of 2 graphs 1 MASTERCAM emulates treatment 3.

2SURFCAM: Inchoate CAM software, treatment operation interface is straightaway, efficiency of process designing treatment is remarkable. But in the light of process designing of label of code of this mould word character, process designing operation is simple, label text also is nonparametric is changed, lot number is updated immediately not easy, bring about process designing efficiency not tall. Refer to a graph 3, graph course of knife of treatment of process designing of label of curved surface of 4 SURFCAM of graph of course of knife of treatment of process designing of label of plane of 4 graphs 3 SURFCAM 3.

3Pro/E: Pro/ENGINEER is a when roll out by company of American parameter technology broad and profound three-dimensional CAD/CAM parameter converts software, its content covered a product to be calculated from notional design, industrial model design, three-dimensional model design, analysis, dynamic imitate and emulate, the whole process that the output that the project pursues, production processes a product, still included the practical module such as design of many cable and piping wiring, mould and analysis among them. Applied domain includes aerospace, car, mechanical, numerical control (NC) a lot of industry such as treatment, electron. Especially the train of thought building a model that complete parameter changes, shortened greatly products plan and change cycle, but CAM module function is not as powerful as CAD module (according to author understanding at present some of company CAD is finished in Pro/E, turn into MASTERCAM next or CAM is finished to machine in Cimatron) , organize the NC form that give with Pro/E, treatment efficiency is inferior (the author once tried to had fumbled the NC of Pro/E is machined, but always feel Pro/E should strengthen its function in CAM module, the treatment way that offers diversity) . Refer to a graph 5, graph screen of course of knife of treatment of label of cant of 6 Pro/E of plan of emulation treatment of label of cant of 6 graphs 5 Pro/E demonstrates 3.

4UG: Unigraphics (abbreviation UG) the dominant product that is American UGS company, also be one of systematic software of the CAD/CAM/CAE/PLM with global the most general application. UG software is in of CAD respect build model and modelling cent to be two module one hypostatic modelling and modelling of free curved surface. In modelling function respect, outside the general function that has except other software place, it still is had agile compound the emulation that builds model, all ready takes a picture, exquisite animation apply colours to a drawing and fast archetypal tool, only compound the random in building a model to be able to let an user build model, curved surface to build draw a frame round of model, line to build model and the parameter that are based on a feature to build model and nonparametric to build a model in entity chooses, make the architect can design actual condition to decide the optimal way that build a model according to the project, get optimal design result thereby. Machining functional respect, UG the practical, adaptability that is aimed at CAM and efficiency sex, through covering production process, the automation that implementation makes, compositive change and the user is changed, make cost and product make face of quality Zhu Fang gave an user to provide huge income in product production cycle, product thereby. It offers way of reliable, accurate cutting tool not only, more the most businesslike machine program in making personnel of NC process designing OK devise a mental view follow one's inclinationsly. 3.

1UG/CAM has following a few characteristics: (1) offers; (2) of reliable, accurate cutting tool method to be able to reach the user interface with good; (3) of the treatment on entity in curved surface directly, the person that allow to use can depend on the need on the job, ; (4) of custom-built user interface offers the treatment way of diversity, went to the lavatory process designing personnel designs; (5) of all sorts of efficient cutting tool method to CAD advocate the model is changed, criterion NC model is changed subsequently. Personnel of NC process designing does not need to cancel the work come again, need to be generated afresh only (Regenerate) knife orbit, knife orbit can be updated instantly; (6) provides complete cutting tool library and function of management of treatment parameter library (of cutting database can use gender and client to change) , make can make full use of newly into personnel the experience of senior staff, the postposition of; (7) CAM of cutting tool method with good design is handled not only those who offerred convention is linear with circular arc interpolation outside, the CNC interpolation controller that still appeared to be based on Nurbs theory (the treatment precision that raised high speed mill, shortened greatly Dao Weiwen length) ; (8) is offerred general-purpose aftertreatment function, produce all sorts of NC to process the NC order with applicable machine (also can construct through the machine tool implement or 2 times the formulate aftertreatment with follow one's inclinations development configures a command) . The application in talking about UG to pile up process designing to machine in mould mark literacy stresses below: UG increased label word to pile up treatment function in CAM module, but in operation of process designing of treatment of curved surface label, feel disadvantageous quite (the author once tried to had fumbled, but did not find better method) . And UG4.

0 added text function newly in CAD/CAM, can effective fast undertake editing in real time updating to text, thereby the rate that very old rate raised to machine process designing (NC program is created afresh after text editor is updated can, need not change any parameter to install, it may be said is get sth done once and for ever) . Highlight those who showed CAD/CAM/CAE/PLM data to not have seam compositive the advantage that reachs parameter to change. 3.

2The word in UG piles up measure of label process designing to be as follows: (1) becomes a word in UG according to the requirement (word code label is on the curved surface of corresponding position) , or turn through other CAD software the file form that gives UG to be able to be accepted guides in UG (text of word code label must be in UG re-edit, convenient the following update immediately) ; The face of yeast for making hard liquor of ball knife treatment that refers to graph 7 (2) to choose diametical 5mm (measure of specific parameter setting is not proud narrate) ; Refer to graph 8 (3) to choose a diameter 0.

The chamfer of 2D of knife of carve characters on a seal of 8mm is machined (measure of specific parameter setting is not proud narrate, the FACE_MILLING_AREA in UG machines module, planar word piles up a label need not (4) pace) ; Refer to graph 9 (4) to choose a diameter 0.

The knife of carve characters on a seal of 8mm is umbriferous treatment (measure of specific parameter setting is not proud narrate, the FIXED_CONTOUR in UG machines module, drive means option is knife course (2D chamfer is machined) ; Refer to processing of postposition of graph 10 (5) to make NC form (the postposition processing that postposition processor deployed system of each type numerical control, the user is OK also to its according to the particular case of numerical control machine tool and numerical control system the database undertakes revise and be compilinged, custom-built oneself only postposition handles an order, the efficiency of NC procedure treatment that UG generates is tall, the merit with NC little file) . 3.

3 words pile up label process designing to update measure to be as follows afresh: (The text label that 1) mouse doubleclicks place to want to change has an edition (edit time to be in 5 seconds probably less than) ; Refer to contrail of cutting tool of recount of graph 7 (2) , create NC program (need 10 ～ 20 seconds probably time, specific time is installed according to operating parameter and decide) ; The author works 1 times in a few days (8 hours) can give NC order about 400 many, the word that completed annual almost piles up task of label process designing. Shortened greatly time of NC process designing, avoided trival and complex parameter setting, get the favour of process designing personnel. Graph 7 UG4.

0 in added text newly to edit functional graph 8 UG to emulate 9 UG4 of figure of face of treatment yeast for making hard liquor.

0 in chamfer of 2D of knife of carve characters on a seal (planar) 10 UG4 of emulation treatment plan.

0 umbriferous (curved surface) emulation treatment (IPW) 4, production machines a result actually: UG4.

The word of 0 piles up label NC form to try treatment in manufacturing site, get the spot operates aircraft personnel reputably. Optimize in cutter track especially, reduce the respect photograph such as the frequency that carry a sword to compare other software particularly remarkable. The mould mark literacy after treatment is piled up and the label word on the mould is piled up. Refer to a graph 11, graph 12 graphs the mould label word after 11 treatment piles up a graph the label word on 12 moulds piles up 5, last word: Unigraphics is born in company of aircraft of American wheat path, from the tool of optimal process designing that is CNC Machining of aircraft spare parts at the beginning, experienced a few years, as coetaneous as it CAD/CAM software (ComputerVision, Calma, EUCLID, Intergraph, Autotrol) have many already die out, only minority experienced long-term production to carry out test and verify to just walk along those who occupy to CAD/CAM/CAE/PLM height number to not have seam compositive peak. The ceaseless development as processing technique and perfect, included a program among them write increasingly simple, choose corresponding software according to the actual condition of each enterprise and can control adroitly it (good process designing technology is not divided with good process designing platform, alleged desire be apt to its thing, surely benefit its implement) , this reduced the computational amount that engineers get on in the program greatly, the workload that also reduced machine tool handlers at the same time and improved manufacturing efficiency, won cost and time for the enterprise. Through piling up the example of the label to this word process designing sets an example and the process designing of other software is compared, showed UG4 adequately.

The 0 advantage in of all kinds software. Because author level is finite, attainments is machined in the process designing that passes this example, share oneself use result each reader, in the effect of cast a brick to attract jade-offer a few commonplace remarks by way of introduction so that others may come up with valuable opinions that this hope can have, make respective one's pygmy effort for treatment manufacturing industry of China.
