Technology Research On Cad Data Quality Measure On Mechanical Product

With the large scale application of three-dimensional CAD system in the company of aviation,spaceflight,auto,machine tool and heavy equipment manufacture industry , the design efficiency of enterprise product become more quickly. three-dimensional CAD model display is straight, but because of the viutual three-dimensional model , so measure is more complex than two-dimensional. CAD model data quality measure research aim at the certain question .The paper depend on the actual requirement and the analyse the actual situation . From three parts research , construct the solution for CAD model quality , and apply the solution to actual question under the Liugong group design situation.(1) Construct CAD model data quality measure repositoryFrom standard muster, enterprise criterion and actual requirement , construct CAD model data quality measure repository and achieve the rule aggregation .(2) Technology study of realizing the measure itemsMainly analyze UG platform' s API, and using API to achieve the commonness to understand API and realize the certain measure item.(3) Form the view of system ,design and realize the measure system prototypeForm the view of system, depending on data management and related technology platform , conceive the entire measuring system and achieve the system and delivery Liugong Group to use. At the same time a good framework for expansion, the combination of sub-module development, for the robustness of their systems, provide a good foundation.(4) Data quality measuring solution for Liu Gong group engineering machine product modelOn the based of constructed repository and rule aggregation ,according to the actual measuring need of Liu Gong group engineering machine product , put forward Liu gong group CAD product solution and demo the constructed system prototype.
