Foreword develops at full speed with what assist production technology as the CAD, the connotation of engineering design line of business and manufacturing industry and the technology had produced profound change related its, this structural design in machinist Cheng domain and functional design respect are behaved particularly remarkable. The structure that the new idea such as virtual reality technology, three-dimensional model technology, parameter design technology already permeated a tradition comes in the design, set of corresponding contrail of cutting tool of computer programmed control and computer machine the new method such as craft parameter to producing unprecedented effect from choose, driving a project to design technology and the development of production technology. The CAD/CAM technology that designs with mechanical design and structure all the time since the writer is old is research direction, the virtual reality technology that insists to explore products plan in the practice of education, scientific research and production, three-dimensional model technology and parameter design a technology, the development that blends in its new product goes in development. In recent years, the mechanical design that the author uses American EDS company to develop is compositive change software Unigraphics Ⅱ (UG Ⅱ ) did many subdesign and auxiliary production job, gained certain experience in the innovation modelling respect of the product especially. In practice, author experience designs a technology to virtual reality technology, three-dimensional model technology, parameter is the development direction of mechanical design, also be the key of CAD/CAM technology. Current, the CAD/CAM software that machinist Cheng domain uses " let a hundred flowers blossom, contention of a hundred schools of thought " , and UG Ⅱ software can because it has outstanding CAD/CAM function,amid shows itself basically is. In modelling function respect, outside the general function that has except place of other however software, 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 build a model to be able to let an user build a model in entity (Solid) , curved surface builds a model (draw a frame round of Surface) , line builds a model (Wireframe) and choice of the random in be based on diagnostic parameter to build a model, 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 Ⅱ software is aimed at the practical, adaptability of the 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. The virtual reality model that the powerful function of UG Ⅱ software has all sorts of complex parts for people and virtual reality are made provided a help. Fall with new-style mouse now modelling design and mould treatment are exemple, the specification is based on the method that the new product of UG software develops and measure. Below the 1 mouse that is based on UG mouse of design of virtual reality modelling is the computer although the bulk in equipment is small but one of conspicuous parts of an apparatus. Its formative is novel all ready sex of gender, use convenient sex and function often is critical essential factor. Design and make a model beautiful, structure the new-style mouse with simple, practical economy is the author the target of this second job. After choosing UG Ⅱ software to issue a design and production development platform as new-style mouse certainly, can begin specific work by undermentioned measure: ① enters environment of UG Ⅱ software above all, open a new document to choose APPLICATION-MODELING module; The CURVE that then choice TOOLBOX menu issues child function, the SPLINE in using this function and LINE command give the mouse in conception to fall in XOY planar draw the outline of outside contour line, will have sharp-angled place to pour round wine cup with FILLET function, after this can make mouse fall the line that distribute a model. Because what random draws in UG software,2 dimension line can be placed automatically to be inside XOY plane, and below this mouse the line that distribute a model is in perpendicular position, because this wants to pass the ROTATEWCS below WCS menu to have XOY plane gyral first, those who make be in perpendicular position, the line distributing a model that can use the ARC function in CURVE to draw it next (show 1 times like the graph) , final choice WCS-ORIENT and WCS-ABSOLUTECSYS function make coordinate department regains initiative position; ② is in different level to make creates entity and auxiliary element part, avoid to happen in molding process promiscuous, must try the working layer when creating auxiliary line, auxiliary face and entity to distinguish, set them respectively here for 1, 5, each 10, accuse with LAYER-SETTING it is the 10th setting working layer, the EXTUDEDBODY in using TOOLBOX-FEATURE next accuses issue mouse axis of Z of contour line edge undertakes drawing in order to get its substance, reoccupy LAYER-SETTING accuses it is the 5th setting working layer, with TOOLBOX-FEATURE medium EXTUDEDBODY accuses issue mouse face of pattern of part of drawing of axis of X of edge of the line that distribute a model. Choose TRIMBODY again right now (hypostatic clip) accuse, divide modular face clip with what just generated this is hypostatic, if the graph shows model system 2 times,get namely; ③ generates mouse to issue the round dambered surface of a below predestined relationship. Can accuse with LAYER-SETTING first it is the 1st setting working layer, the ROTATEWCS that falls through WCS menu accuses rotate XOY plane perpendicular position, draw one oblique line with CURVE-LINE inside XOY plane again, accuse with CURVE-ARC next fall in mouse front draws 1/14 circular arc. Should make coordinate fastens extensive to recover from an illness right now, go to working layer switch the 5th, with TOOLBOX-FEATURE medium EXTUDEDBODY accuses become drawing of axis of X of this diagonal edge one cant; Again set job layer is 1, with CURVE-INTERSECT (beg cross a line) seek this cant and hypostatic week range cross a line; Go to working layer switch the 5th, choice TOOLBOX-FREEFORMFEATURE (scanning) accuse, fall circular arc edge the line to undertake scanning getting one dambered surface; Choose TRIMBODY finally (hypostatic clip) , with the dambered surface clip that just generated this are hypostatic, the graph shows mouse model substance 3 times; Tectonic now mouse issues ④ particular structure. Fall to create mouse central aperture, make one cylinder with CYLINGER first, choose SUBSTRACT parameter, subtract entity this cylinder can get this hole; Build bottom round hole steps leading up to a house with HOLE next; Reoccupy HOLLOW takes whole substance case. So far, below this mouse structure of main body appearance already modelling ends, undertake mouse leaves an in-house function next the design of fine structure and its modelling, reinforcement, coupling, fixed position piece, installing hole add one by one, undertake proper Xiu Leng is mixed horn is designed with respect to achievable whole modelling (integral model attempt is shown 4 times like the graph) . Below the 2 mouse that are based on UG after virtual reality machined process designing to should finish above to establish model and modelling procedure, can serve as data base to weave with them CNC Machining program. Choose index of right treatment kind, technology and cutting tool parameter through be being mixed in the set in MANUFACTURING module, again thick, finish machining takes set cutter track line produces cutting tool contrail from this, can undertake this below new-style mouse CAM. To assure to design and machine quality, can emulate on preexistence computer show and trends examines NC knife course, whether mutual collision, cutting tool mixes such as cutting tool and clamping apparatus whether mutual collision, curved surface machines the spare parts to whether produce the problem such as excessive cutting all attainable immediate result, be helpful for revising treatment parameter in time, finish treatment job satisfactorily in order to assure. What need points out is, the postposition processing of the CAM is quite important, the Dao Weiwen as a result of the work out before this (Cls file) be order a document one kind, must change into ability of M code file to apply through postposition processing at machining a process. The character of numerical control machine tool that when module is undertaking postposition is handled, the postposition processing of UG software needs describes a file (Mdfa file) can arise through man-machine interaction by the MDFG program of besides, accordingly, project technology can is opposite according to specific treatment circumstance Dao Weiwen undertake postposition is handled, the made NC code that becomes numerical control machine tool to be able to identify. Production function of the function of virtual reality modelling of software of UG of application of author of 3 last words and virtual reality develops new-style mouse to fall, because used virtual reality technology, three-dimensional model technology and parameter to design a technology,wait for new idea and new method, saved a design time, assured to design quality, and drafted treatment plan, have the effect of get twice the result with half the effort. This explains: Use UG software to have the development of new product, cycle weak point, quality is high, and can become an organic whole repeatedly with treatment, realize CAD/CAM without seam compositive. Also make the author is experienced from this, the domain is designed in mechanical design and structure, fictitious design and fictitious making is a development way that deserves exploration.
