“…For instance, NX and its PLM) solution Teamcenter are aimed at offering a complete solution from design to manufacture [64]. In contrast, an increasing number of industry companies have adopted neutral formats for data exchange; in the course of data exchange technology development history, several international standard data formats were proposed, such as IGES, PDES, and STEP [67]. Among these standards, STEP is the most advanced and complex, covering almost all the applications used in each product lifecycle phase.…”

“…4. The purpose of NDF is to transfer data from all applications into a NDF, which requires the development of pre-and post-translators for each computer system involved to enable data transfer [67]. This significantly reduces the number of interfaces needed, as well as development effort and maintenance complexity.…”

“…Later versions of IGES such as IGES 2.0 and IGES 3.0, published in 1982 and 1986 respectively, laid the foundation for extended and further refined later versions up to IGES 5.0 and IGES 5.x, which contain now, besides the original two and three dimensional wireframe models and associated standard dimensioning formats, also rational B-spline based curves and surfaces, solid models, finite element modeling data and a limited set of product specific data [9,10,11]. Further details and references on other standards developed in parallel to IGES, such as VDA-FS, VDA-PS and SET for the exchange of CAD data and partial product data, can be found in [12,13,14].…”

Despite international efforts to support specification and exchange of CAD data through acknowledged standards and data interfaces, in practice several problems still remain. One type of problem is related to the reconstruction and verification of CAD data containing defects. Major problems causing such defects are related to differences in the internal modeling accuracy of systems. Generated models that sometimes contain degenerated edges and faces having either almost zero length or zero area exacerbate the situation. Defects in the topology and / or the geometry of such geometric models have a severe impact on computeraided post-design processes such as finite element analysis, STL file generation, tool path generation, etc. In the meantime, until improvements can be made in the processes that generated those corrupted CAD data, correction of possible errors in CAD data can be achieved by introducing an intermediate post-processing step aimed at reconstructing an error-free, valid solid model. Within the given scope of this paper, we introduce and investigate the application of a face-sewing operator, which can be applied to CAD data based either on surface models or on solid models. Operation and quality of the model reconstruction are determined by the tolerances of spatial model space points located on the face boundaries and their distances apart. Due to the use of reference kernel architecture featuring a Brep scheme within an integrated multi-dimensional topology supporting both surface models and solid models, a CAD data interface based on a standard data exchange format and an internal translator that classifies, converts and correlates pure geometric entities, sub-setting geometric entities and topological entities, open and highly flexible system architecture in respect to considered CAD data and geometric models can be maintained.

Practical implementation of a STEP-based architecture to provide a fully integrated and interoperable platform of data exchange has always been an intriguing issue. A variety of CAD/CAM environments are struggling to embed and support STEP standard and its protocols in order to seamlessly operate within global data exchange. However, apparent paucity of efficient and reliable structure for data communication, manipulation, and restoration has remarkably hindered the desired progress. In this paper, taking these shortcomings into account, a practical architecture is introduced and STEP-based agents are implemented and installed on the platform. Moreover, feature recognition, interaction, and machining precedence as crucial issues of CAD/CAM research have been considered in developing the interoperable platform. Seamless integration and interaction of CAD/CAM modules are provided in the proposed system. The prototype is finally verified and discussed through a case study.
