【正文】 識的智能化模具 CAD/CAM系統的研究、高速切削加工及其編程等是未來研究發展的趨勢。220。172。172。172。172。 the free shape in space design is the art of the product shape to design, making product been not only is a function product, but also art article。 a product model that pass through way can increases biggest new product design mature curved face anti beg to set up the mold software has: Surfacer,The CAD technique exchanges of the molding tool business enterprise with cooperate to have many pass the CAD document method the CAD system category is more, therefore documentary format must follow the international standard,Such as the DXF, IGES, STEP, VDA, etc. of to read standard format document to establish directly or establish the product model after modifying, since can quickly, deepen the customer and the exchanges of the molding tool factory house,Also can shorten the product the design the period. 3, the CAD design of the molding tool and analysis The CAD design of the molding tool, analysis,Include to divide the type, certain type 199。 with mold 208。 ), analyze the temperature pressure variety circumstance and analyze to note 203。 。204。 processing, line incising to process, electricity spark processing to technique of CAM rises in the type 199。 of the electrodes process particularly more important main technique characteristics includes:(1) the 180。 process the craft parameter to really settle,(4)The monness slices the 207。 product model profession puter plait distance software,such as MASTERCAM, UNIMOD, etc. of CIMATRON, when the plait distance of many curved faces processes have the higher request to the curved face model of the product,Intend with the high accuracy of the curved face to match such as the directional consistency, curved face in U, V of the close together curved face, inclined rate in curved face continuous variety etc..In high class CAD/ the integral whole of CAM turn system,( such as UGII, PRO/ E) Because making use of the parameter turns the characteristic shape design with same database technique, making the type 199。 CAD entity models are longlost set up a series of a layer data of the thickness, make use of the laser take shape machine or others take shape the equipments read these datas,Increase the method technique with the material, pile up the each layer to take shape one by one in technique calls the fleetness to take shape the technique automatically.( Rapid Prototype)It is also a CAD to gather the technical importance constitutes the part. The first pedestal takes shape the equipments quickly to bear in the United States a pany in 1987, because of its characteristics is to has nothing to do with the plicated degree of the product of the manufacturing, bringing the manufacturing industry the enormous decade,Take shape quickly the technique be flown to develop soon, the category of the equipments also piles up one after another,Turn from the material 185。 rubber mold, low 200。 steel mold。s knowledge turn molding tool CAD/ the system of CAM slices the 207。208。 mold with porcelain and ceramics or metals 187。 anticipates, porcelain and ceramics, metals etc. all can take shape, taking shape the piece is heatproof and bear the burthen with apply color the ability stronger,Have the extensive and applied other method also gets the application in some special kinds process. According to above take shape the method characteristics, take shape the technical function quickly to consist in primarily:The manufacturing useds for the design with the on trial product model, make to used for the small the molding tool that batch quantity produce to process with the special spare parts in small batch shape the product model of the technique manufacturing quickly in the aspects of material the ratio tradition processes the product model of the method manufacturing has the difference, But in shape and sizes almost plete similar, and there is certain machine strength, can make the function experiment, handles through surface at the same time, looking similar to true product,Can advertise the propaganda shape the molding tool of the technique manufacturing quickly,Is a soft material to take shape the mold( the mold of 192。 model data, knife,The modification knife of the product model has the track to also modify molding tool processes the entity imitates the true technique more and more mature, also is more and more valued by is mimicry machine bed that processing the entity imitate process the process on the puter, can keep the result that view reflect process,Can takes the gauge of directly quantity that after processing spare parts, can check the mistake that check quantity that after processing spare parts, can at the puter is last to process behind of the entity model proceeds the aleatoric 198。 process controls,(5) over slice the check with process the superficial accuracy control,(6) processing the puter entity of the process imitate the realistic 207。 processes the knife have the track excellent to turn the programming with the instruction of NC creation,(2) the knife has the category, characteristic to establish with the material 191。 of the plicated molding tool and the 207。Iu ml。 whether to cool off asymm
