1, overview mankind society develops up to now, already experienced thousands of years of research and exploration, gather rich and generous knowledge fortune and fruit of science and technology in every respect, it is the base that the product develops, it is precious fortune of the mankind. But the confine as a result of the history, in the times that does not have the computer, most bequest is recorded with simulative means, in current digitlization times, want to use these knowledge and achievement quickly, solid belong to inconvenience. This is about to beg the model that digitlizes many imitate information translate into, in order to offer later product development is used. In mechanical product side, we can use the idea of converse project, measure with 3 coordinate machine come apace completes transition. Reverse the history that the mankind is explored and studies, you can discover, on the foundation that each achievement is advanced person research, imitate nature and human society to come true in the relevant domain, thing that has relevant strong point, character, animal or person. See day aerial flyer, we were modelled on plane, dan Fei machine flies higher than the bird, faster, farther; See the whale of sea middle reaches, people was modelled on submarine, but submarine goes than whale get deeper, bulk force of potential of bigger, add is more powerful; ... mankind of this that is to say has thing, research in study all the time existing thing, be modelled on existing thing, namely the mankind works in the means that uses converse project all the time, be modelled on not only archetypal, and surmount prototype. Through appearance people calls the process that develops a product converse project, with the product to the design the process is contrary. Converse project basically is research other people or existent system or product, discover its law, with the duplicate, process that improve and transcends existing product or system. Converse project is pair of real worlds not just imitate, be pair of real worlds more transform, it is one kind is surmounted. The crucial technology that it involves basically includes: Data of appearance of three-dimensional and hypostatic geometry is collected, regulation or three-dimensional and a large number of discrete data processing, hypostatic model rebuild, treatment. 2, 3 coordinate are measured machine the data that is converse project is collected implement, 3 coordinate measure the data source that is converse project machine it is close come a few years, the measuring instrument of a kind of of as the flying development of course of study of the computer, machine tool generation efficient high accuracy implement. It uses the principle that coordinate measures, below the control of computer software and drive, complete pair of workpiece geometry dimension and form the 3 coordinate data of tolerancepublic errand is collected. It organic ground combined a number to control a technology, used computer software technology, used advanced position to pass feeling technology and accurate orgnaization technology, the perfect union that makes. It complied with the technology that hardware software changes to develop way, make lever of eddy of such as gear, cam, turbine need is special before detect equipment ability completes work, can measure with general 3 coordinate now machine undertake data collect, union is measured accordingly, evaluation software comes to those who realize major detect, evaluation function. Measure the principle of machine through understanding 3 coordinate, people knows its advantageous character very easily: Efficient, high accuracy, Gao Rou sex and have sexual special sex. Use advanced pass feeling technology, number to control technology, computer to software is controlled and handle a technology, make 3 coordinate measure machines and tools to have very tall data is collected and handle efficiency; It is a foundation with accurate mechanical main body, use software control and compensation technology, match the positional sensor with high accuracy again, can realize very tall precision. It realizes what dimensional coordinate nods to measure, use computer software to complete product geometry dimension, form the evaluation of tolerancepublic errand, the product of different type should adjust software to be able to be finished only, this makes already 3 coordinate measure machines and tools to have very tall flexible, have corresponding special sex again. Converse project should be modelled on sample, be about to have corresponding data news. Data collects the start that is converse project, it is the primary activity of converse project. Be based on the character of afore-mentioned 3 coordinate, can say 3 coordinate are measured machine the data that is converse project ideal is collected implement. 3, the data in converse project collects a program to collect program purpose is to make collection data accurate and efficient. Correct it is the data that shows place is collected enough report appearance characteristic and won't produce misdirect misunderstanding; Efficient it is to show in what can show item characteristics correctly the circumstance falls, collects data as far as possible the little, route that has taken as far as possible the short, time that spends cost as far as possible little. Collect to product data, have a basic principle: Go along diagnostic direction, collect to direction down the law. Be just like the train, go along orbit, gather digital information down crosstie. This is general principle, answer actually to be decided according to particular product and converse engineering software. A respect is divided to introduce below. The data of regular form collects a program: Dot, linear to regular form such as, circular arc, planar, columnar, conic, ball, also include to expand regular form is like hyperbola, corkscrewed yarn, gear, cam to wait, data is collected multi-purpose the contact probe with tall precision, the dot information that according to mathematical definition these elemental place want undertakes data collects a program, here does not do overmuch specification. Although we are the appearance end of a few products feature, but real product cannot be academic appearance, treatment, use, of the environment different, also affecting the figure of the product. Those who serve as converse project measure a program, cannot stay in only " feature " draw-out on, should consider the metabolic trend of the product more, analyse namely form tolerancepublic errand. Next watches are each regular element maths the number of the most decimal foothold that the description wants, want to describe its public errand and change, real need measures more places. The data of free curved surface collects a program: To be not regulation appearance, curved surface of freedom of a general designation, use blame contact probe or both photograph band more. In principle, want to describe the product of free appearance, should record enough several foothold information only can, but foothold of judge sufficient enough is very difficult. Real data collects a program in, the integral feature of much basis workpiece and flow direction, undertake going down the feature, the data that the law sweeps to the feature collects a program; Greater to local change place, still use this one principle to undertake dividing a complement. Intelligent data collects a program: Current intelligence data is collected still be in just began phase, but it is the target that 3 coordinate measure machine place to go after, it includes type automatic fixed position, automatic element identifies, collect program and automatic data automatically. 4, the research and development of effective tool product that converse project is product research and development is not a castle in the air, need is mixed in existing product research and development has on the technology, existing product is not have mathematical model and data news, the kind that people often needs to use converse project will undertake counting occupying collection mixing mathematical model is reductive. When general product just was beginning the work, be not be in groove, after wanting the job for some time, through the effective clench the teeth of interagency, ability obtains better working position, at this moment the geometrical dimension of departmental cent mixes the product form just we design a pursuit tolerancepublic errand. But at this moment of product and design unvarnished already had certain difference, need gets the data below status of current and good job with the means of converse project, in order to improve a design. Visible, converse project is the effective, applicable tool of product research and development. 5, the product in converse project rebuilds the program is converse the data processing process of the project includes: The analysis has product or system, to its the principle undertakes draw-out, combinative new technology, improve and surpass existing product (the 3rd step is concrete be to the project) . Analysis: The analysis has product or system, find out the crucial data of its job principle. Show level to manual analysis, automatic analysis and intelligence analyse pattern of 3 kinds of analysises. Draw-out: Identify each element in giving product prototype and each character from inside data by certain regulation, draw-out also be a data filter and add close process. The product rebuilds: Rebuild to divide line wearing to rebuild by rebuilding means, face piece rebuild with whole. From the line by people the thinking means to the face undertakes line wearing rebuilds, CAD/CAM development is inchoate rebuild software uses line wearing basically to rebuild mode. The line of current popularity is worn reframe software basically has UG, ProE, Catia, Surfacer, CopyCAD to wait, among them Surfacer and CopyCAD are online wear draw-out respect to have distinguishing feature very much. Face piece rebuilding is direct from appearance chamfer is smoked in data piece, afore-mentioned software can finish such job, but the effect is not ideal, its are main the reason is cent piece and joining together not be very convenient and effective. The ICEM software that ProE gives newly is in face piece rebuild the respect has distinguishing feature very much, it can assist an user to finish cent piece and automatic joining together. Rectifying weight to build is intelligence actually change rebuild process, include line wearing to rebuild already knead dough piece rebuild, the entity that includes a product again is tectonic, main by software automation the ground is finished, its pay attention to product whole more. The digital product that converse project place produces, it is the digitlization of real product, can work in the simulative in simulative environment at the same time condition, eliminate and improve the inadequacy of current product prototype, surmount sample thereby. 6, treatment treatment is digital product translate into the process of real product, the program of treatment and data collect the place that has a lot of likeness, here explains more nevertheless. The machines the automation that pays attention to treatment craft more and treatment automation of converse project is finished. 7, the impulsion that summary is modelled on is product development, converse project is the efficient way of product research and development. Converse project measures 3 coordinate machine tool of software of machine, CAD/CAM/CAE, CNC organic and efficient union is together, make a of product research and development and production efficient, convenient way. Converse project is a product not just be modelled on, it more what bear a move in chess or a movement in wushu learns a model is reductive optimize with what design again wait for multinomial important task. Current, although converse project developed to already obtained great progress, the concept of converse project is thorough already popular feeling, be applied extensively at each domains, it is the research and development of mechanical product not only; Advanced company uses converse project mode to have product research and development and production in succession. But the process that converse project returns the product is a not complete maturity, each link still remain at be being perfected further, exploration and research, do not have very perfect solution. 3 coordinate are measured machine the data source that serves as converse project, its dimension remains to be worn at face super- large and exceed miniature two way develop; Its measure a head to remain to be worn at face way of efficient, quick, multipurpose develops; Function of its software requirement is powerful and the operation is handy, algorithmic but sex of put sb in a very important position is strong. Converse project reframes mediumly software asks to reframe border of tall, operation mixes efficiency reframe the effect is good. Anyhow, 3 coordinate are measured machine forward intelligence changes directional development, converse project also forward intelligence changes directional development. CNC Milling
