TL;DR: This paper elaborates on the role of PLM as a knowledge management system and a lack of clear understanding of what PLM is, its core features and functions, and its relationship to the myriad of current software tools is explained.
Abstract: Competitive success of manufacturing firms is by and large determined by the success of the products they introduce to the market. This is why companies continuously try to improve the efficacy of their product realization process. Product Lifecycle Management (PLM) is a business solution which aims to streamline the flow of information about the product and related processes throughout the product’s lifecycle such that the right information in the right context at the right time can be made available. Yet, few organizations are positioned to reap the true benefits of PLM. One major reason for this is a lack of clear understanding of what PLM is, its core features and functions, and its relationship to the myriad of current software tools. This paper aims to do that and also elaborates on the role of PLM as a knowledge management system.

TL;DR: In this article, a new Design for Additive Manufacturing (DFAM) method is proposed that supports part and specification modeling, process planning, and manufacturing simulations, based on the process-structure-property-behavior model that is common in the materials design literature.
Abstract: Additive Manufacturing (AM) technologies, informally called “rapid prototyping,” enable the fabrication of parts and devices that are geometrically complex, have graded material compositions, and can be customized. In this paper, we focus on cellular materials and structures, which can lead to designs that are very geometrically complex. In order to take advantage of AM capabilities, new design and CAD methods must be developed. Two advances are reported in this paper. First, a new Design for Additive Manufacturing (DFAM) method is proposed that supports part and specification modeling, process planning, and manufacturing simulations. The method is based on the process-structure-property-behavior model that is common in the materials design literature. Second, Manufacturable ELements (MELs) are proposed as an intermediate representation for supporting the manufacturing related aspects of the method. These MELs represent process planning information for discrete geometric regions of a part and also...

TL;DR: In this paper, a computer-aided design for additive manufacturing (DFAM) method is presented that is based on the process-structure-property-behavior model common in the materials design community.
Abstract: Additive Manufacturing technologies enable the fabrication of parts and devices that are geometrically complex, have graded material compositions, and can be customized. To take advantage of these capabilities, it is important to assist designers in exploring unexplored regions of design spaces. This paper explores the opportunities and challenges in design for additive manufacturing. A new computer-aided design for additive manufacturing (DFAM) method is presented that is based on the process-structure-property-behavior model common in the materials design community. Examples of cellular materials design and manufacturing are used to illustrate the DFAM method.

TL;DR: A classification of the various methods of 3D mesh segmentation based on their corresponding underlying fundamental methodology concept as well as on the distinct criteria and features used in the segmentation process is given.
Abstract: D mesh segmentation is a fundamental process for Digital Shape Reconstruction in a variety of applications including Reverse Engineering, Medical Imaging, etc. It is used to provide a high level representation of the raw 3D data which is required for CAD, CAM and CAE. In this paper, we present an exhaustive overview of 3D mesh segmentation methodologies examining their suitability for CAD models. In particular, a classification of the various methods is given based on their corresponding underlying fundamental methodology concept as well as on the distinct criteria and features used in the segmentation process.

TL;DR: In this article, a requirements-driven approach to innovation is proposed, which is a natural extension of the system of customer requirements in terms of their number and type and the expanded ways of collecting and processing them.
Abstract: Innovation research is highly interdisciplinary and has attracted numerous science and practice communities. Though innovation results are broadly applicable, this paper focuses on engineering and service domains. The two are tightly interrelated, as the benefits of product innovation are realized through the business activities, and certain business undertakings may impact the product design innovation. A requirements-driven approach to innovation is proposed. It is a natural extension of the system of customer requirements in terms of their number and type and the expanded ways of collecting and processing them. The proposed approach is implemented as the Living Innovation Laboratory.
