Description
Technical field
The invention belongs to the technical fields of aeronautical product technique manufacture, and in particular to a kind of Aviation product digital prototype
Processing examination system.
Background technique
Aeronautical product development has the characteristics that technical difficulty is big, quality requirement is high, long period, to be related to subject wide, certainly
Determine necessary just can guarantee using advanced theory and means and completes development task as required.Technological design is set as connection product
The bridge of meter and product manufacturing, generated process data is one of most important data in product lifecycle, and
The important evidence that enterprise formulates production plan, carries out production scheduling plays very heavy during the entire product development of enterprise
The effect wanted.It basis of the processability review of product as technological design must be by technologist to product zero in product design process
Part structure etc. carries out processability review of product and finally determines reasonable structure with manufacturability, the assembling capacity etc. for determining product
With technical process.
With the promotion of product design concept and the development of 3-D technology means, the development of aeronautical product had been established with
MBD(Model Based Definition, the definition based on model) technology be core design and manufacturing technology system.MBD skill
Art described using three-dimensional entity model it is all design and manufacture technique information, the product feature that is included, geometric dimension with
Tolerance etc. defines the foundation that information also has become technological design and the manufacturing.
It in external Aeronautic Product Project development process, has been achieved with technique and is cooperateed with the online of design, technologist is logical
Crossing related system can interact in product design process with designer, propose technique opinion and obtain design of feedback, make to produce
Product manufacturability, assembling capacity have just had reached expected requirement in the design phase.Currently, Domestic Aircraft, which develops industry, mainly factory
Two kinds of development modes of separated mode and integrated manufacturing system (IMS).Under the separated mode of factory, design institute adheres to two separately with manufactory
Legal entity is usually to design department's concentration by the process part door expatriate personnel of manufactory to production for Processing examination work
Product data carry out Processing examination, and examination result is fed back to design department in the form of paper document.Integrated manufacturing system (IMS)
Under mode, by building online Collaborative Developing platform, design department may be implemented and opened with technique department based on unified digital prototype
The online collaboration of exhibition works with Processing examination.Under this both of which, digital prototype coordinates to examine that being all based on document mode carries out, i.e.,
Technologist manually checks product information in modelling platform, and examination result is manually entered papery review list, and
Designer is fed back to, designer obtains the corresponding modification of progress attribute, mark and digital-to-analogue after examination reports, Processing examination mould
There are the following problems for formula:
(1) lack corresponding software tool assisted review work, to improve the efficiency and quality of Processing examination, finally improve product
Development efficiency and level；
(2) the effective control that can not achieve checking process causes manufacturing sector cannot be anti-in time to the examination result to design a model
It is fed to design department, the efficiency of extreme influence Processing examination；
(3) Classification Management for examining data is not implemented, causes the problems in product development process, experience that can not track and count,
It is even more impossible to be used for reference in subsequent models development process；
(4) mode of the Processing examination based on paper document management more falls behind, and can not achieve the process and knot for coordinating Processing examination
Effective tissue of fruit and control.
In conclusion under complete three-dimensional aircraft digital manufacturing mode design information, manufacturing process information acquisition and
Transfer mode is more flexible, and the online collaboration for how realizing that high efficient technology examines, design and craft examines becomes this field urgently
It solves the problems, such as.
