Recent Achievements in Numerical Simulation in Sheet Metal Forming Processes

Purpose of this paper: During the recent 10-15 years, Computer Aided Process Planning and Die Design evolved as one of the most important engineering tools in sheet metal forming, particularly in the automotive industry. This emerging role is strongly emphasized by the rapid development of Finite Element Modelling, as well. The purpose of this paper is to give a general overview about the recent achievements in this very important field of sheet metal forming and to introduce some special results in this development activity. Design/methodology/approach: Concerning the CAE activities in sheet metal forming, there are two main approaches: one of them may be regarded as knowledge based process planning, whilst the other as simulation based process planning. The author attempts to integrate these two separate developments in knowledge and simulation based approach by linking commercial CAD and FEM systems. Findings: Applying the above approach a more powerful and efficient process planning and die design solution can be achieved radically reducing the time and cost of product development cycle and improving product quality. Research limitations: Due to the different modelling approaches in CAD and FEM systems, the biggest challenge is to enhance the robustness of data exchange capabilities between various systems to provide an even more streamlined information flow. Practical implications: The proposed integrated solutions have great practical importance to improve the global competitiveness of sheet metal forming in the very important segment of industry. Originality/value: The concept described in this paper may have specific value both for process planning and die design engineers

Оптимизированный процесс обмена данными в период между проектированием и производством

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.Растущее разнообразие вариантов транспортных средств, законодательные требования по сокращению выбросов CO2 ими, инновации в области технологий трансмиссии в сочетании с усиливающимся давлением, направленным на сокращение расходов, ставят новые задачи перед участниками автомобильного сектора. Внедрение оптимизированных процессов разработки и производства поддерживает эффективное решение этих проблем. Одним из важных аспектов является повышение эффективности инженерных решений за счет оптимизации всего процесса разработки кузова и управления данными. Исследовательская деятельность сосредоточена на процессах обмена данными на этапах проектирования, моделирования и производства в различных средах САх. Это касается постоянно меняющихся граничных условий и требований к разработке кузовов автомобилей, включая, помимо прочего, внедрение новых материалов и их комбинаций, а также новых технологий сборки. С точки зрения поставщика автомобильной техники, необходимо учитывать дополнительные факторы, вызванные различными средами проведения разработки, которые обусловлены потребностями пользователя. Чтобы решить эти проблемы, нужно изучить стратегии обмена данными между ОЕМ-производителями (ОЕМ – производитель оригинального оборудования) и поставщиками автомобилей с использованием различных инструментов. В статье представлен оптимизированный процесс обмена данными на основе САD (компьютерное проектирование) между различными средами CAD и CAM (компьютерное производство), который поддерживает разработку всего кузова, включая предоставление необходимых показателей для производственного цикла. Кроме того, оптимизация процессов обмена данными позволяет уменьшить затраты на разработку и улучшить качество продукции

Set-Based Concurrent Engineering Model for Automotive Electronic/Software Systems Development

Organised by: Cranfield UniversityThis paper is presenting a proposal of a novel approach to automotive electronic/software systems development. It is based on the combination of Set-Based Concurrent Engineering, a Toyota approach to product development, with the standard V-Model of software development. Automotive industry currently faces the problem of growing complexity of electronic/software systems. This issue is especially visible at the level of integration of these systems which is difficult and error-prone. The presented conceptual proposal is to establish better processes that could handle the electronic/software systems design and development in a more integrated and consistent manner.Mori Seiki – The Machine Tool Compan

An assembly oriented design framework for product structure engineering and assembly sequence planning

The paper describes a novel framework for an assembly-oriented design (AOD) approach as a new functional product lifecycle management (PLM) strategy, by considering product design and assembly sequence planning phases concurrently. Integration issues of product life cycle into the product development process have received much attention over the last two decades, especially at the detailed design stage. The main objective of the research is to define assembly sequence into preliminary design stages by introducing and applying assembly process knowledge in order to provide an assembly context knowledge to support life-oriented product development process, particularly for product structuring. The proposed framework highlights a novel algorithm based on a mathematical model integrating boundary conditions related to DFA rules, engineering decisions for assembly sequence and the product structure definition. This framework has been implemented in a new system called PEGASUS considered as an AOD module for a PLM system. A case study of applying the framework to a catalytic-converter and diesel particulate filter sub-system, belonging to an exhaust system from an industrial automotive supplier, is introduced to illustrate the efficiency of the proposed AOD methodology

CAx/EDM integration : enabler for methodical benefits in the design process

Over the past decade, the development of engineering information technology has led to a rapidly increasing number of process-supporting engineering systems. At the same time, substantial advances in engineering methodologies and practices are being introduced, often at an even greater pace than support systems. Closing this gap is paramount for optimal engineering processes, especially when developing complex products like such as passenger cars. This paper will take a look at today\u27;s and tomorrow\u27;s engineering practices, which are the key to further progress in reducing costs and time and optimising the product development process
