Abstract:

The use of computer-aided design (CAD) technology in the U.S. Navy and marine industry has evolved from a drafting-based design tool to a three-dimensional (3D) product-oriented information base, used for design, production and service life support. One of the most significant enhancements to current CAD technology has been the incorporation or integration of non-graphic attribute information with traditional graphics data. This expanded information base or product model has enabled the marine industry to expand CAD use to include such activities as engineering analysis, production control, and logistics support. While significant savings can be achieved through the exchange of digital product model data between different agents, current graphics-based CAD data exchange standards do not support this expanded information content. The Navy/Industry Digital Data Exchange Standards Committee (NIDDESC) was formed as a cooperative effort of the Naval Sea Systems Command (NAVSEA) and the National Shipbuilding Research Program to develop an industry consensus on product data and to ensure these industry requirements are incorporated into national and international data exchange standards. The NIDDESC effort has resulted in the development of a suite of product model specifications or application protocols (APs) defining marine industry product model data. These APs have been submitted for inclusion into the next generation of data exchange standards.

Abstract:

Abstract Feature-based translation of computer-aided design (CAD) models allows designers to preserve the modeling history as a series of modeling operations. Modeling operations or features contain information that is required to modify CAD models to create different variants. Conventional formats, including the standard for the exchange of product model data or the initial graphics exchange specification, cannot preserve design intent and only geometric models can be exchanged. As a result, it is not possible to modify these models after their exchange. Macro-parametric approach (MPA) is a method for exchanging feature-based CAD models among heterogeneous CAD systems. TransCAD, a CAD system for inter-CAD translation, is based on this approach. Translators based on MPA were implemented and tested for exchange between two commercial CAD systems. The issues found during the test rallies are reported and analyzed in this work. MPA can be further extended to remaining features and constraints for exchange between commercial CAD systems.

Abstract:

As a new design and manufacture paradigm, Cloud-Based Collaborative Design (CBCD) has motivated designers to outsource their product data and design computation onto the cloud service. Despite non-negligible benefits of CBCD, there are potential security threats for the outsourced product data, such as intellectual property, design intentions and private identity, which has become an interest point. This paper presents a novel secure product data exchange (PDE) in the processes of CBCD. Different from general cloud security mechanism, our method is content-based. We first show an outline of the collaborative scenario to describe the architecture of the proposed secure CBCD, in which a security mechanism is combined with the data exchange service to achieve secure PDE. Second, we present a novel grid-based geometric deformation method for the security mechanism with three processes: the original shapes of a source Computer Aided Design (CAD) model can be hidden by deforming the control grid; then the deformed grid can be exchanged to target system where a deformed target CAD model can be reconstructed; at last, the deformed target CAD model can be recovered to the original shape after recovering the deformed grid. Finally, typical CAD model tests demonstrate that our method can keep the sensitive information of source model and also maintain the same level of data exchange error.

Abstract:

On the basis of analysis and summary of the research of the others, we choose the notepad as the carrier of the data file and a code as the expression of the feature information of the products, embedding them in the 3D CAD system like a plug-in unit. In this way, the products’ data accurate transmission between distributed and isomeric CAD systems over the internet is realized. This method can also be used in the real-time collaborative design system.

Abstract:

Successful and efficient exchange of product model data has been a major challenge in the shipbuilding industry for the past two decades. The Standard for the Exchange of Product Model Data (STEP) has been developed to enable this capability. Four STEP application protocols (APs) to facilitate the exchange of structural and distributed systems models in shipbuilding were completed in 2003 and were adopted by the International Organization for Standardization (ISO) by mid-2004. In August 2003, ISO 10303–216: Ship Moulded Forms (AP216) became the first shipbuilding STEP AP to be published as an international standard. Participants involved in these efforts represent several major US shipyards, the Navy, and their computer-aided design/ engineering (CAD/CAE) vendors. The thrust of shipbuilding data exchange efforts has now shifted from development to implementation. This paper will report on efforts to develop and use translators for this AP to exchange hull form product data in the ship modeling and simulation arena. In addition, process simulation is becoming common in the design of new ships to validate that the design meets the customer's specifications. Current technology requires that the ship be modeled both in the computer-aided design (CAD) environment and then repeated in the simulation workbench. Not only is this effort inefficient, but it is inherently error prone. Through the National Shipbuilding Research Program (NSRP)-sponsored Integrated Shipbuilding Environment (ISE) projects, we have developed tool sets that use AP227: Plant Spatial Configuration to permit the design to flow smoothly from the CAD workbench to the simulation workbench. This paper summarizes the efforts to develop and use a suite of tools that enables US shipyards to become more productive. It details the specific successes in using AP216 and AP227 for modeling and simulation, as well as efforts to exchange design data electronically between CAD systems. The report also outlines efforts that are underway to use other APs to successfully exchange data describing ship electrical; heating, ventilation, and air-conditioning (HVAC); and controls systems.

Abstract:

The design and construction of any marine vessel designed on a computer-assisted design (CAD) system, from a nuclear aircraft carrier to the smallest work boat, requires the interaction of many electronic databases, all of which must be continually updated for the work to proceed. The exchange of this information, especially geometry, in digital format is accomplished using many different tools and techniques. Much has been presented to the marine community about the tools used, such as the Initial Graphics Exchange Specification (IGES) and the Standard for the Exchange of Product Model Data (STEP), and how these tools might be used for exchanges in the future, but little has been presented on how production data exchanges actually occur. At Electric Boat, current submarine programs cannot wait for future data transfer solutions. Design and construction data must be exchanged among various activities, internal and external, with such volume as to make manual reentry of data an unrealistic solution. Because of the complexities associated with the electronic exchange of these data, the General Dynamics (GD) Marine organization of Electric Boat has a dedicated group that both performs production data exchanges and researches and implements new methods of electronic transfer. This paper discusses the rationale for and the formation of the data exchange group at Electric Boat, along with its place within GD Marine. It then presents an overview of the tools used by the group and how production transfers occur, both routine and unique. Notable transfers provide examples of how the group works to solve transfer problems. Importantly, this paper shows how many of the exchange standards developed for the marine industry actually work in production. Special emphasis will be placed on the exchange of solid models in a day-to-day environment. The paper concludes with a look at the future of production data exchanges for Electric Boat and the larger marine industry.

Abstract:

The application of computer-aided design (CAD) and manufacturing (CAM) techniques in the marine industry has increased significantly in recent years. With more individual designers and shipyards using CAD within their organizations, the pressure to transfer CAD data between organizations has also increased. The Navy/Industry Digital Data Exchange Standards Committee (NIDDESC) provides a mechanism for public and private organizations to cooperate in the development of digital data transfer techniques. Organizationally, NIDDESC is a cost-sharing venture between private firms and government organizations. This effort arose from the Naval Sea Systems Command (NAVSEA) in cooperation with the National Shipbuilding Research Program. The members include leading professionals in the marine industry from several major design firms, private shipyards, naval shipyards, and government laboratories. All members are directly involved in CAD/CAM in their organizations and together represent a broad spectrum of experience and perspectives. NIDDESC has many subcommittees devoted to specific areas of digital data transfer. The basic objective is to develop an industry-wide consensus on product data models for ship structure and distribution systems. Efforts include contributions to the Initial Graphics Exchange Standard, the Product Data Exchange Standard, preparation of a Recommended Practices Manual and the analysis of ship production data flows. NIDDESC has made contributions to the development of CALS standards, including MIL-STD-1840, DOD-IGES, SGML, and MIL-D-28000.

Abstract:

This article highlights that by using a standard that enables complete product model data to be transmitted digitally, a company can build open systems to make information available on many platforms throughout its operations. The world of CAD/CAM has viewed the International Graphics Exchange Standard (IGES) as its translation standard for years, using the system to move two-dimensional models from one program to another. While IGES does, in fact, do a good job of transmitting basic geometry, another translator—the Standard for the Exchange of Product Data (STEP) —has been gaining on IGES in popularity. STEP goes considerably further than just transmitting geometry; it provides users with the ability to express and exchange digitally useful product information throughout a product's life cycle, including design, analysis, manufacturing, and support. In short, IGES transmits two-dimensional drawings, while STEP transmits complete product models. The updated schema, consisting of an ASCII file written in EXPRESS, is simply run through a utility that merges the extensions that have been added by Unigraphics with the standard ST-Developer libraries. Updating the translator to incorporate an upgraded version of the libraries is just as easy.

Abstract:

Nowadays, most 3D casting process CAD systems are developed based on second development tools of various 3D CAD systems. However the type and version escalation of various 3D CAD systems in foundry enterprises greatly limit the application of 3D casting process CAD systems. By the data exchange between the neutral file format of 3D geometric model, these problems can be well solved. In this study, by taking advantage of universal CAD data-exchange standard iges for data exchange, a practical 3D CAD system was developed based on opencascade geometry kernel. The system has the function of design and modeling of practical casting process such as part information extraction, parting surface, gating system, riser system and so on. Finally taking a steel casting for example, the casting process is exported in the file of stl and the simulation analysis is carried by intecast software which demonstrate the system based on iges neutral file can well support the integration of casting CAD and CAE.

Abstract:

Growing vehicle variant diversity, legal requirements to reduce fleet CO2 emissions and innovations in the area of drive train technologies, coupled with the increasing pressure to cut costs, pose new challenges for parties in the automotive sector. An implementation of optimized development and production processes supports the effective handling of these challenges. One important aspect includes engineering efficiency improvement by optimizing the entire automotive bodywork development process and the involved data management. Research activities focus on the data exchange processes between design, simulation and production engineering within various CAx environments. This concerns constantly changing boundary conditions and requirements in the area of automotive body development, including but not limited to the introduction of new materials and material combinations and new types of joining technologies. From the viewpoint of an automotive engineering supplier, additional challenges caused by different customer-related development environments have to be considered. To overcome these challenges, various data exchange strategies between OEMs (Original Equipment Manufacturer), automotive suppliers and the use of different data management tools need to be investigated. In this context, the paper presents an approach of an optimized data exchange process of CAD-based data between different CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) environments that supports the entire body development, including data provision for manufacturing engineering. In addition, an optimization of data exchange processes saves development costs and improves the product quality.

Abstract:

Hewlett-Packard develops and markets a family of computer-aided engineering products used by high-frequency designers to model the signal path in contemporary communications systems. As design frequencies, clock speeds and packaging densities continue to increase, more designers are finding that system and circuit simulation products need to be complemented by electromagnetic simulation software to develop models for basic circuit functionality or to characterize and compensate undesired parasitic effects. The HP High-Frequency Structure Simulator (HP HFSS) is a frequency-domain, finite element-based simulator, which enables engineers to characterize high-frequency behavior in 2D (transmission lines) and arbitrary 3D structures. Links with mechanical computer aided design (CAD) software have also become more important as the 3D structures to be analyzed by HP HFSS can involve packaging parasitics when the housing in which the electrical circuitry is enclosed becomes an influence on the signal path. Depending upon the complexity of the structure to be analyzed, HP HFSS can require hundreds of Mbytes of RAM and disk during automated adaptive solution convergence processes which determine field and circuit parameter solution results to user-specified accuracies. Although computer resource requirements will always be an important consideration for users of this type of product, another important situation to address for the future involves the exchange of data between the different simulation and modelling tools required to take design from concept through simulation to manufacture. The introduction of physical simulation tools into the traditional circuit simulation arena changes the design process flow and increases the demand for improved integration and interoperability of circuit simulators, numerical EM simulators, and mechanical CAD software. This paper provides an overview of data exchange issues in high-frequency electrical–physical–mechanical design processes.

Abstract:

Flexible integration concepts for computer-assisted design (CAD) and manufacturing (CAM) systems have been identified as a key to let shipyards select and implement best-in-class software components for their CAD and CAM operations. Current implementations are dominated by bilateral links based on proprietary data exchange formats and are too complex to upgrade parts of a CAD/CAM infrastructure without negative impacts on the other parts. This paper describes the ongoing development of a connector architecture for CAD and CAM systems in shipbuilding. The architecture decouples CAD and CAM systems on the basis of a flexible integration technology, utilizing XML data exchange, lightweight directory access protocol (LDAP), and message-based communication. An enterprise reference model describing all relevant shipbuilding business objects forms the basis for the integration. So-called adapters connect the various CAD and CAM systems to the architecture. An automatic nesting solution is presented as a sample business solution in the connector architecture environment.

Abstract:

A CAD/CAM system has become a dominant system in modern production techniques. In the attempts to facilitate the transfer of design data and geometry between the huge varieties of the International working CAD/CAM systems, the International Standard for the Exchange of Product coding system (STEP) is introduced (ISO Step AP-203). Extraction of the entities is the first step in the automated programming either for process planning, product classification or in programming for Numerical Control Machine Tools. This step is the aim of this paper in a line of several steps to build a complete CAD/CAM system for manufacturing of complicated products. A methodology is developed to extract each entity. Software has been built using Visual Studio C# - Version 2010. Interface is designed giving all the entities and showing the geometrical shape of the product. Different cases have been tested to verify the developed software and full successfulresults were obtained.

Abstract:

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.

Abstract:

A generalized approach to fast interpretation of objects and their features has so far eluded researchers. In manufacturing, this interpretation can be approached from the vision point of view or from the CAD data perspective. Presently, CAD systems are widely used in several aspects of manufacturing production. It is therefore more efficient to use CAD data for object reasoning in manufacturing, especially when systems will eventually be data driven. Components can be modelled on a CAD system using various modelling techniques and the representation of their geometric information is still CAD system dependent. However, the advent of the Initial Graphics Exchange Specification (IGES) now makes it possible to represent CAD data in a neutral and standard manner.This paper describes a scheme for recognizing and representing features for CAD data extracted using the IGES interface. The concepts developed are based on graph-based feature representation, where features are represented by a set of faces as well as their topological adjacency.Strategies for classifying features and methods of decomposing a complicated feature into several simpler features for recognition purposes are discussed.

Abstract:

Product development is becoming more complex. Product design is desired to be undertaken together with the considerations of downstream processes such as manufacturing and assembling. The product data exchange between CAD and PDM systems is a crucial issue for the integration of product development systems. To solve this, this paper focuses on a flexible, unified data model based on PDM that integrates information and models from different engineering domains. Some key technologies, such as type of data organization and data exchange between PDM and CAD, are researched based on the case of Smarteam. This approach has been experimented within a company environment that designs and produces families of the hydraulic press parts.

Abstract:

An international standard (ISO 10303) has been created to facilitate the exchange of product models between diverse computer-aided design (CAD) systems. Informally known as STEP (standard for the exchange of product model data), this specification has been under development since the mid 1980s, and parts of it were approved as international standards beginning in 1994. Efforts to expand STEP to meet the needs of the shipbuilding industry have been in work for many years and are nearing completion. By early 2003, it is expected that four application protocols to facilitate the transfer of information relating to ship structures, piping, and heating, ventilation, and air-conditioning will have been approved as international standards and become part of the overall STEP standard. This article discusses the successful efforts to expand STEP to meet the needs of the shipbuilding industry, as well as outlining the various implementation and testing projects that have been undertaken to ensure the validity and success of these new standards.

Abstract:

The methods of data exchange between CAD and CAE systems are described. The first method is using direct conversion, the second method is using neutral formats. The description of the modular system for designing and analysis the strength and stability of single-contour and double-contour geodesic shells GeoTran is given. The direct translation of geometric models from ArchiCAD to Patran/Nastran / Dytran has the disadvantage of having to develop translators for each data exchange scheme. It is proposed to implement the translation of geometric models in a neutral STEP format, which reduces the number of required translators. It is noted that the STEP format is recognized by various CAE systems that implement the finite element method (Autodesk Mechanical Desktop, Bentley Microstation, CATIA V4, CATIA V5, MSC Patran/Nastran, UGS PLM Solutions NX). The characteristics of the OBJ format used for storing a geometric model in the ArchiCAD CAD system and the STEP format used for data exchange with CAE systems are studied. A translator of geometric models of single-contour geodesic shells from ArchiCAD to STEP format in the Visual Basic programming language has been developed. For this purpose a syntactically oriented approach was used. The translator has a graphical user interface that makes it easier to use. The translator allows you to automate the exchange of data between the ArchiCAD CAD system and various CAE systems designed for strength analysis and supporting import from the STEP format. The applicability of the translator for the exchange of data on geometric models of single-contour geodesic domes with triangular plates between ArchiCAD and the Delcam Exchange converter program is verified. It is demonstrated that the STEP file format generated by the OBJSTEPTranslator is recognized by an external program.
