5, AutoCAD R14 interface, imitate machining process reachs a principle, produced clear result, the three-dimensional and dynamic imitate in developing application software machines a graph. Will three-dimensional dynamic imitate is united in wedlock effectively with CAD/CAM, described thoroughly design and make a process. The products plan that is used successfully at the manufactory and make reach teacher and student. Virtual reality technology is making the main way that CAD/CAM develops, those who emphasize fictitious prototype is fast generate and evolution, it is fictitious make the application that designing a domain -- what be a center in order to design is fictitious make. And mechanical production process is emulated have many complex figure, contrail of its spatial motion also is compared accordingly complex. The scrap of the generation in be like machine tool, cutting tool, clamping apparatus, workpiece and cutting process, product is machining the content in the process to flow, general software designs three-dimensional model quickly hard, realize complex motion contrail and complex graph. Accordingly, in the three-dimensional graph of the product the existence in establishing model, design is worn how to build a model quickly, undertake fictitious prototype designs the product, be aimed at this problem, we use fast design method to build fictitious and three-dimensional model, with VB6.

5, the edition that AutoCAD R14 interface completed the three-dimensional and dynamic figure that has complex motion contrail and processing, showed a space complex motion contrail, a few movements of imitate machining and behavioral principle, produced clear result, a few software of development are used at education and scientific research, can move below environment of memory of WINDOWS platform, 64MB. 1 three-dimensional and fictitious model devises theory according to fictitious prototype, the spare parts is fictitious and archetypal comprise by the geometrical element of computer graphics, spare parts curved surface needs to use enchase algorithm and polygonal network to approach, hypostatic spare parts is approached with much face. The design method of three-dimensional and dynamic graph has a lot of. The article puts forward the method of a kind of machining to undertake building a model quickly, more three-dimensional than be built with simple calculation method model wants its algorithm simple, quick. Graph 1 auger, enlarge, bore with a reamer dish a graph of process of spare parts treatment process of treatment of bore of face of 2 cars step is on modular machine tool undertake to workpiece bore with a reamer is machined getting enlarge (1) seeing a picture, the leave out in the graph gets pattern plate. The opposite correlation that its move is 3 above component moves: Undertake machining with much knife in lathe, car face of two a flight of stairs, bore (2) seeing a picture, it is more complex that its machine process model and athletic contrail. To the three-dimensional trends of afore-mentioned treatment process the graph is designed, be about to build fictitious production model above all (Virtual Manyfacturing Model) , fictitious design and making must be to build the base that creates design of foundation, tooling in mechanical design production principle and product. In design of three-dimensional and dynamic graph and figuration process, we regard the three-dimensional graph design of mechanical product part is process of treatment of a kind of spare parts, it has all sorts of treatment plan, if the three-dimensional model of reamer machines a process (3) seeing a picture, the spare parts in dynamic graph makes a process make a process for three-dimensional spare parts. Like method of design of planar assembly drawing, three-dimensional ＂ assembles ＂ to pursue also is by each graph of three-dimensional spare parts assembles graphical graph. Does contrail of 2 three-dimensional and dynamic motion design equation of contrail of movement of three-dimensional and dynamic figure (namely: ? ? of P of  of large   is the athletic contrail according to treatment process gives out directly. We can decompose all sorts of complex motion into simple motion, simplified so algorithmic. Be like auger, does the athletic contrail of the treatment process of enlarge, bore with a reamer decompose: ? Poison knocks at the fluctuation shift of difficult Zuo direction and the roll that wind Z way: The machine tool workbench after processing a work circles the graduation whirligig of Z axis, the whirligig that workpiece follows workbench and after processing a work, install process of semifinished product of a work, (Bore with a reamer is over after aperture) the work that takes the next to had been machined, these machine dynamic process to express with time function T(X) , and the variable that sets every three-dimensional spare parts to be X, have Xi={X1, x2, ... Xn} , when designing dynamic contrail, undertake designing by time Tx and the relation that spare parts Xi moves, can assure each synchronism of three-dimensional spare parts and opposite motion. In machining a process, it is feed idle stroke in the begining, do not have scrap at this moment, the ability when treatment has scrap. When because this fictitious treatment process is three-dimensional dynamic graph is designed, design scrap into object of a hidden, we regard them as a group of spare partses, be concealed when bore begins to machine scrap by small the athletic contrail that presses a design to the earth and synchronism of Tx cutting tool are shown slowly come. Graph 1 with the graph 2 it is the treatment process when Tx=50 frame. Graph the spare parts in graph of 3 three-dimensional and dynamic imitate makes a system afore-mentioned example can see, treatment process can become visible three-dimensional and dynamic figure from single plan change, make thereby CAD/CAM visualize, visible, be close to production more actual, shortened products plan makes cycle, can achieve efficient, fast, nimble, the purpose that trial-produce succeeds, reduced cost effectively. Afore-mentioned three-dimensional and dynamic imitate is used successfully at education process, make mechanical workmanship and engineering are produced to reality from abstract dimensional thinking, improved education result effectively. Name of the cease after making three-dimensional and dynamic graph can be changed directly with 3D is the file of Avi and VB or VC++ interface. The basic method that the three-dimensional and dynamic figure that 3 conclusion offer machines, regard process of three-dimensional graph design a kind of spare parts machines a process. Devised the three-dimensional and dynamic plan in machining a process with this method. This method is simple, quick. With VB6.
