Convenient connection technology data model supporting optimized information exchange between CAx-systems

Abstract

Increasing diversity of types and decreasing batch sizes along with a growing complexity of products manufactured by forming technology result in new challenges for developers and designers. The construction of a full parametric model of a deep drawing tool in a 3D CAD system is usually considered time-consuming and associated with high cost, and thus discourages many designers. In order to render this type of modeling easier and faultless, a new method for the model-driven design of deep drawing tools is developed. For this purpose the analysis of fully parametric 3D CAD models of deep drawing tools is necessary. This analyzing contributes to the newly developed graphical domain-specific language, which makes the modeling of deep drawing tools more flexible and time-efficient.

Data Exchange with Support for the Neutral Processing of Formats in Computer-Aided Design/Computer-Aided Manufacturing Systems

“…As a result of the high pace of development, the requirements for the information to be transferred and the methods for transferring knowledge, information, and data between designers and engineers have increased. Transfer issues have posed serious obstacles that have only been defined recently [31,67].…”

“…Krause [30] highlighted the significance of the rapid transfer of CAD data between different CAD systems to speed up and reduce the number of iterative steps in product development processes. Kreis' research [31] involved the use of a large volume of data in the development process, especially in the applied CAx environment, and an examination of the exchange of data between different areas of design, analysis, and production in the automotive field. The assessment of data formats for layered manufacturing was discussed by Kumar [32] and by Varga in terms of the machining process [33].…”

A Data Management Approach Based on Product Morphology in Product Lifecycle Management

“…Xia uses meta-models to describe data in the stages of product design, process manufacturing, sales operations, and maintenance [4]. Kreis uses meta-data to describe CAD data and integrates with PDM systems [5]. Tao uses meta-models to describe the basic structure and content of the data set, enables the retrieval and integration of heterogeneous data from different data sources [6].…”
