The invention supports the gradual reasoning generation of the complete tolerance specification design label according to the sequence of each stage of the complete product life cycle, so that the complete tolerance specification design label is distributed in a plurality of levels, each level corresponds to one stage of the product life cycle, and each stage generates a tolerance specification design label block with a certain degree of completeness. The product life cycle here mainly refers to the functional tolerance design, manufacturing and metering certification of geometric products. Wherein, the Functional tolerance design mainly refers to the Correlation between the product function and the Functional tolerance parameter and the tolerance band (simple out-simplified tolerance specification design label, for example, 'Ra, 3.3 um'), that is, the function-related phase (Functional Correlation); the final aim of the processing, manufacturing and metering certification is to reduce the uncertainty of the tolerance specification design label to the minimum, namely to automatically generate the complete tolerance specification design label for engineering technicians.
FIG. 1 summarizes the intelligent generation of the complete tolerance specification design of the present invention, which is actually a refinement from the simplest tolerance specification design marking at the top level to the complete tolerance specification design marking at the bottom level. Taking the two-dimensional surface profile tolerance specification design of the surface as an example, the two-dimensional surface profile tolerance specification design mainly comprises four levels:
1) the first level-L evel 1, this level focuses on automatically generating all the corresponding simplest tolerance specifications design labels that best characterize the functional requirements of the geometric product, actually matching a geometric feature to be associated for each functional requirement of the geometric product, and matching a most suitable tolerance parameter and tolerance band for the parameter for each associated geometric feature, i.e. a function-related process.
2) A second level-L evel 2, this level emphasizes the generation of a semi-complete tolerance specification design annotation which uses fuzzy inference rules at this level to infer default symbolic indications, default values or optimal suggestions based on the latest GPS standards for 5 core pattern symbols and operational data, including indications of specification limits, filter types, transmission bandwidth, length of evaluation and comparison rules.
3) And a third level-L evel 3, which is mainly to add symbols and related operation data specially used for guiding the manufacturing process and the type to the semi-complete tolerance specification design marking block generated in the second level, wherein an inference machine on the level can deduce and obtain the symbol marking of the manufacturing process and the symbol marking of the manufacturing process according to the geometrical characteristic type, the manufacturing direction, the tolerance band value, the cut-off wavelength and other defined manufacturing process information graphs or matrixes.
4) And a fourth level-L evel 4, which is mainly used for reasoning and generating related symbols and operation data for indicating the work of the metering authentication stage based on related knowledge in a GPS authentication standard file integrated in a multi-level GPS tolerance knowledge mode, wherein the related symbols and the operation data comprise a measuring condition, a measuring instrument, a measuring method, a measuring data processing method, a measuring result evaluation method and the like.
For example, in AutoCAD, if tolerance specification designs need to be marked on complex geometric product design patterns, the most simplified tolerance specification designs can be marked directly on the electronic patterns, and when subsequent metrology personnel need to measure and authenticate the product, the calibration personnel can move a mouse to the corresponding tolerance specification design marking blocks to select and display tolerance specification design marking blocks with different degrees of integrity on different levels, and the currently displayed marking blocks can respond to double click of a left mouse button to pop up a pop-up menu containing a text box of a list, which comprises semantic detail explanation and operation specification guide of all symbolic elements and data, so that all tolerance specification design marking blocks can generate a plurality of compatible design models and design data under the condition that different geometric design specifications need to be extracted, and the readable design data of the product can be generated under the condition that different tolerances and geometric design specifications can be achieved by adopting a dynamic multi-level tolerance specification design visualization modeling mode (a software module) and a dynamic multi-level tolerance specification design visualization marking mode (a software module) can support the requirements of designing visual marking of different geometric products according to different marking environments, and different requirements, and can ensure that all tolerance specification design data can be generated under the compatible requirements of the compatible design models generated by using extensible and the XM software (a variety of the design models and the design models generated by using the compatible design models generated by using the XML.
During an AutoCAD editing session, a database may be obtained for the current graphic by calling the following functions: acdbHostAplicationServices () - > workDatabase ()
After the tolerance specification design and marking custom entity class is realized, a user adds a mark symbol, namely a specific entity object is created, and then the object is added into the current AutoCAD database, so that the tolerance mark symbol can be added into the current AutoCAD graphical interface. The following code is a function for adding a tolerance marking entity object to the AutoCAD database:
when the labeled entity object is to be modified, the selected label object can be modified and updated only by acquiring the selected label, then obtaining the handle of the object by using the function acdbgetObjectId (), and then opening the object by using the function acdbOpenObject ().
The use process of the embedded geometric product intelligent tolerance specification design and marking software package in AutoCAD is as follows:
1) firstly, after starting the AutoCAD drawing software, loading a software package file GPSTolerantec Callout.arx;
2) if the menu item added with tolerance specification design labels can be seen at the end of the menu bar of the AutoCAD software after loading is successful, the menu item can be operated to design, generate and label the tolerance specification design.
While the embodiments of the invention have been described in detail in connection with the accompanying drawings, it is not intended to limit the scope of the invention. Various modifications and changes may be made by those skilled in the art without inventive step within the scope of the appended claims.
