The error on understanding of hardware of 1 pair of software to going up CAD project project, to the policymaker of a few enterprises, it is to fall to buy workstation of how many computer, printer, graph plotter, big screen to wait for the thing that sees so that see be being felt really mostly. And to software, a few pieces of CD, want to spend a good deal of money, as " copy " software will use. But the software of the copy is on the function, the respect such as technical service is to cannot get those who assure. However, we understand project of great majority CAD to invest is to be used at buying hardware. The end that uses CAD technology is generation benefit, the organic union of software and hardware just can act well truly. To computer hardware, buy need not the most harmful, it is impossible to keep a cost. Everybody knows, 18 months add the operation speed every other of the core CPU of the PC one times (possible even fast) . Buy the computer now, do not follow two years to go up later tide, perhaps 2/3 did not have its value. So where did its value go? Its value is the benefit of the generation in use process. Scale of investment of foreign soft hardware achieved 7 ∶ 3(commonly namely the capital of 70% is used at software, 30% use at hardware) . Be aimed at domestic actual condition, come over 3 ∶ 7 or 5 ∶ 5 also be should OK those who accept. 3.
The understanding that software of 2 CAD develops 2 times has different product as a result of different company, it is endless and identical that its design structure of method, product. Current, the commodity CAD software on market belongs to the general development tool that contains general character feature, buy the software that fits need of all products plan impossibly from software company. This namely the account that CAD software all offers development means 2 times, for example AutoCAD, already provided the language that has 4 kinds of 2 second development at present. So, when project of the CAD on the enterprise, appropriate takes development problem seriously adequately 2 times. 3.
The key that the technology of education CAD of talent of 3 pairs of CAD application uses successfully depends on a talent. The enterprise should notice to strengthen CAD technology to apply the talent's education above all. The stress that company person with ability develops is applied good software, solve real problem. The talent key of institution of higher learing and scientific research unit is development. Generally speaking, the development person with ability that him small and medium sized business develops CAD technology is unsuited. Should take the way of joint development application. 4 pairs of proposals that extend applied CAD technology deep can believe completely, in different area technology of disparate industry CAD will obtain thorough promotion to apply. How to combine feeling of national condition, province, have the promotion application of CAD technology in the light of afore-mentioned problems, I think work of the following fields is important. 4.
Technology of 1 development CAD seeks advice from service industry technology to seek advice from a service is connection a kind of bridge of businessman of soft hardware of object of each business application and computer. Want to deepen technology of promotion application CAD, due the orgnaization of advisory service system with higher level of relatively more perfect, indifferent, technology serves for the enterprise. Its are main task responsibility is: (1) grooms to advisory argumentation of enterprise CAD plan, technology, debug system of test, software to safeguard, move to support and be improved perfect, also include the advisory service such as communication network, database, PDM. (2) is collected, the example that arranges enterprise CAD system to fail successfully. Put forward according to technical development a few current program of relatively proper systematic soft hardware. (3) collects the relevant data of CAD system software and development trend, undertake assessment to index of common CAD/CAM system performance, offer a report. (4) changes development according to 2 needs to undertake software users of the enterprise and groom industry technology qualified personnel. The technology seeks advice from a service to be in abroad already industrialization, but belong to in home just start level, need what the government gives policy and capital to go up to give aid to, provide necessary soft hardware environment. This is one is helpful for enterprise, service the technical activity at the society, the industrialization road that can move toward ego to develop stage by stage only comes up. 4.
The 2 measure authors that deepen technology of promotion application CAD think " throw drawing board " need of this kind of formulation is extended on range and deepness, include two fields: It is to attract more businesses, especially promotion of small and medium sized business uses CAD technology, participate in " throw drawing board " project; 2 it is the CAD technology that uses real significance on quality in the light of disparate industry, disparate arrangement of ideas, contain computer plot not just, due still the content such as management of archives of design analysis, CAPP, graph. Accordingly, in the enterprise applied CAD technology can divide for following 3 paces: (The broad sense of the unifinication such as plot of 1) promotion design, 2 dimension and three-dimensional design, CAD and CAPP, CAE, CAM " throw drawing board " project. (2) to the design information is compositive develop with administrative depth, data of promotion application product manages (PDM) technology, make the enterprise marchs toward C3P(CAD/CAM/CAE/PDM) stage by stage. (3) uses an advanced technique to realize the CAD on real significance, include ground of collateral project, distributinging different to cooperate design, optimize fictitious and design and intelligent design, fast prototype to make etc. 4.
For the enterprise that the research that 3 support are oriented CAD technics with application transforms to market economic system to be in, the competition that should meet market economy adequately to emphasize the first principle, this decided the company is right technical forward position, especially the demand that products plan technology innovates, and the deepens application to will conduce to this one target implementation of CAD technology. Current, beginning to study CAD system is not actual from the ground floor of 2 dimension plot. The author thinks to answer be in a kind or on the software platform of a few kinds of in a popular style, open architecture, be aimed at the specific requirement of production enterprise, undertake is the research of the CAD technology direction of the target in order to apply. To supporting CAD fundamental application technology studies the key should put in the following respects: (1) branch line of business has a base, the 2 peace keeping of standard general part are three-dimensional the job that build a warehouse. Current, 2 Wei Jianku's jobs are more mature already, three-dimensional and hypostatic design is development direction, 2 dimension and three-dimensional and mutual union should be a kind of mode of CAD of domestic company application. Current, appropriate begins the development work of the three-dimensional software that build a warehouse as soon as possible. (2) is based on research of compositive technics of CAD/CAM/CAE of unified product model. Generally speaking " throw drawing board " after the target is achieved, the information that should march toward design process is compositive level. Although many CAD/CAM software systems claim,be compositive, many problems still exist in be being used actually, because this answers,begin those who combine company product characteristic to build a model to be the core, compositive technology research that is guidance with STEP standard with the feature. (3) has the research of CAPP software platform of certain versatility. Current software of the CAD/CAM on market is very much, but have not have as popular like AutoCAD CAPP system, the reason is multiterminal of workmanship problem change, object of different company, different product, same product but the company with production different resource its workmanship differs likely. Accordingly, be aimed at some kind the tool of demand development CAPP of production enterprise is expected to succeed. (4) product data manages (the research of PDM) and collateral design method, what collaboration of ground of the pattern of management of product information resource that lays in network environment especially, distributinging different designs mode to wait to already fundamental theory studies is necessary, have wide applied perspective again. Abroad considers to still also belong to task of technical forward position in this respect, for example the efforts that CSCW(computer supports works) , be based on the design of Web to wait to still be in exploratory study phase. Regard a technology as preparation, supporting the research that has this side also is significant. CNC Milling CNC Machining
