Description
Technical field
The invention belongs to 3-dimensional digital micronizing technology field, and in particular to a kind of generation method of three-dimensional values file.
Background technology
Definition (MBD) based on model be one with integrated three-dimensional entity model come expressed intact Product Definition information
Product size, tolerances marking rule and technique information expression in method body, its specified in more detail three-dimensional entity model.MBD
The essence of technology be defined by information carrier of product threedimensional model product design, manufacturing process, Fixture Design, assembly technology,
The information such as inspection, are used as unique foundation and data source in product lifecycle each stages such as design, manufacture, inspection.State's outgoing
Successful experience up to country proves that MBD patterns are the successful approach of Digital Design and Manufacture, and such as Boeing Co. uses MBD skills
Art realizes the height of the links such as the aeroplane structure design of Boeing 787, technological design, Fixture Design, part processing, assembling, inspection
Fusion and cooperate with, be truly realized the three-dimensional digital, with no paper of airplane design manufacturing process, substantially reduce aircraft development week
Phase.Domestic manufacturing industry is also wideling popularize MBD technologies, and more grind is achieved in terms of the promotion and application based on MBD technologies
Study carefully achievement.But totally apparently, the domestic research to MBD patterns is also in the exploratory stage, and relevant design instrument and management regulation are also
Need further perfect, particularly with detection, conventional two-dimensional pattern is remained at present.
As the link of checking on of product quality, detection person believes according to technologies such as detection elements, detection requirement, detection modes
Breath, coordinates product component material object to carry out detection activity.The forming process of detection file is at present：Upstream design personnel are according to production
Product function and performance requirement carry out three dimensional design work, by projection transform into two-dimensional engineering graphic, expression product size, tolerance,
The design requirements such as material；Technologist understands product design requirement according to two-dimensional engineering graphic, and the two-dimentional process sheet of establishment is used for
Guide product manufacturing process；For detection, technologist is on the basis of technological procedure card, with reference to product component detection
Complexity, as needed generation detection operation guiding book, for the intermediate detection process of product manufacturing, often also need to life
It is used for reference into corresponding process drawing；Above-mentioned two-dimensional engineering graphic, process sheet, process drawing and detection operation guiding book one
And workshop is issued to, detection person knows figure first, and detection key element, detection requirement etc. are then identified from many paper documents
Detection information.Detection information carrier is more under this pattern, express not directly perceived, and error-prone, detection information acquisition efficiency is low, detection person
Need to extract detection information in many parts of files, especially for complicated machine-made spares, detected size value volume and range of product is more, to inspection
Survey work and bring very big puzzlement.
In addition, as three-dimensional digital design is in product design, the popularization and application of process procedure, especially MBD technologies
Popularization and application, the letter such as product design, manufacturing process, Fixture Design, assembly technology, detection is defined by information carrier of threedimensional model
Breath, is increasingly obtained as unique foundations in product lifecycle each stage such as design, manufacture, detection and the trend of data source
It is widely recognized as.And the main carriers of traditional mode detection information foundation are two-dimentional drawing and derivative process sheet, work
The file such as skill accompanying drawing and detection operation guiding book, with upstream three-dimensional design data source disunity, easily causes characterization processes ambiguous
Property, inspection planning and product design change asynchronous, information content missing, the problems such as information transmission is obstructed.
Three dimensional design, the three-dimensional process research for being currently based on MBD technologies are relatively broad, i.e., the core according to MBD technologies
Thought, based on threedimensional model, expresses information of the product in different phase, example by the way of geometry, three-dimensional labeling and attribute
Such as in Design Stage, product 3-d modelling is built in CAD system, product size, public affairs are expressed by the way of three-dimensional labeling
The technical requirements such as difference, benchmark, surface roughness, coordinate attribute mode to describe the information such as product figure number, title, material；In technique
Design phase, according to designing a model for three-dimensional labeling, technologist generates the corresponding three-dimensional process model of each procedure, with more
Intuitively, can interactive operation mode Instructing manufacture manufacturing process.Detection is generally divided into on-line checking and the class of offline inspection two.
On-line checking refers to include in process flow or with other work posts merge to form a procedure by detection, and workman completes Process Planning
After Cheng Zhiding content, confirm that processed mass property can be transferred to the behavior of next procedure after meeting the requirements by self-inspection,
Detection node is not embodied in process route, the product quality typically implemented by workman oneself and formed to oneself process operation is special
Property be responsible for.Offline inspection refers to that the parts that will be machined are sent to the detection station specially set, and work is pressed by full-time detection person
The behavior that detection node specified in books part and requirement are detected and judged to product.
Detection is as the process in process sheet, and its process model construction has itself particularity compared with other processes.
First, detection process generally not involves the change of product geometric properties, and its process model geometric feature is with detecting a upper procedure
The corresponding geometric properties of model are consistent.Secondly, detection object, which is related in process route, detects all process steps or two before process
The corresponding detection of process requires that detection information species is more, and the detection method and instrument of use are different, and portion between road detection process
Relevance between go-on-go measurement information is strong, and the structure to detection process model brings larger puzzlement；Finally, detection information species
It is many, detection object and detection are required quickly to position and the demand of search is higher.
In consideration of it, the present invention proposes a kind of generation method of three-dimensional values file, using three-dimensional values process model as core
Detection of expression information, Uniform Product design, technique, detection data source, gets through design-technique-manufacture-detection data message chain
Road, in plant site by terminal devices such as computer, flat board, indication control boards, is closed by three-dimensional visualization means and detection information
Connection technology realizes the quicklook expression of detection information, and auxiliary detection person carries out detection work.
