Sustainability and economic factors are increasingly pushing industry towards environmentally friendly manufacturing methods. However, the implications of processing level changes, which are being introduced at a significant rate, for overall, environmental impact need better characterization. In the first half of this paper, a simplified framework for enhancing sustainability in manufacturing, by enabling rapid assessment of approximate life-cycle implications of competing process-level alternatives, is introduced. This framework relies on developing or enhancing manufacturing process models in such a way that a superior quantitative evaluation of the environmental and economic impacts of decisions made in manufacturing process planning can be established. In the second half of this paper, the specific case of metal machining is presented. In machining the maximum attention has been directed towards reducing the traditional profligate use of metalworking fluids. Consequently, a significant quantity of research work has been directed towards developing dry and near-dry, or Minimal Quantity Lubrication (MQL), machining techniques. A review of available literature shows that several outcomes of these techniques for product life-cycle assessment need to be addressed — i.e., some environmental tradeoffs are often involved in their implementation. Avenues for further research in sustainable machining, including some ideas for advancing dry and near-dry machining without resorting to chemical action for extreme-pressure lubrication, are also presented.

Geometric Tolerances

Tolerance information plays a critical role in many steps of the product life cycle. It is especially important due to the advances in Internet technologies and increasing integration requirements from industry. In this paper, geometric tolerances information in manufacturing process (IMP) is studied, and the layered conformance level of geometric tolerances is established according to ASME Y14.5-1994, STEP and DMIS. An EXPRESS-G data model of geometric tolerance information in IMP is established. The XML language is used to represent and program the geometric tolerances information in IMP.

AbstractGlasses are becoming more and more important as part of our daily life. The product is an interesting and general. People's needs in this regards are different. In this research work a case study of product life cycle management of smart glasses for future use is presented. Research is thorough and quantitative. Basic objectives that were to establish are the reasons for wearing sunglasses, the most important characteristics that glasses must meet, setting the fashion trends for glasses and provides market strategy for selling glasses until recycling. On the basis of research done on sample of 30 people, different option were put in front of them the most important were chosen, which are, built-in speaker for playback, capacity to store memory, connectivity to external devices (PC) and Radio/MP3. Market strategy is also set for the glasses from factory to the recycling including customer feedback, environmental concerns. Conceptual design of the glasses using computer aided design is also presented. This multidimensional product is an achievement in innovation, entrepreneurship and gives good insight into the implementation of engineering education through product life cycle.

Material Information

Materials play a central role in product manufacturing, contributing to each phase of product development in the form of either a component or process material. As the product revolves around materials, so does much of the product information. Material information plays a significant role in the decision making process at any stage of the product life cycle, especially with respect to the sustainability of a product. Material information in the manufacturing stages of a product’s life cycle will relate to the processes used in manufacturing and assembling individual components. The material properties may determine what processes can be used and how these processes should be controlled. To support sustainable manufacturing, the impacts of material choice should be considered during design, when resources are being committed. When comparing material alternatives at design time, it is not as simple as saying one material is “more sustainable” than another. Many different factors determine the sustainability of a product, and each of these factors may be influenced by multiple material properties represented through various information requirements. In order to develop a material information model that can satisfy these information requirements, we need to carefully study the requirements from an information modeling perspective. In this paper, we use activity models to describe design and manufacturing scenarios that rely on the availability of proper material information for sustainability decision making. We will use these models to first define specific scenarios and then to identify the types of material information that is typically required in these scenarios, and collect and categorize key concepts. Based on this study, we will make recommendations that will aid the development of a useful material information model for sustainable decision making.

Desktop Application

Life cycle assessment software packages such as SimaPro, GaBi, and Umberto have become well-established tools for conducting environmental impact analysis. However, applications for broader sustainability assessment are limited. Recent research has developed an information modeling framework to compose models of unit manufacturing processes for sustainability assessment and has led to the definition of unit manufacturing process information modeling concepts. An engineer can use the framework to conduct manufacturing system-level sustainability assessments by composing models of unit manufacturing processes. Assessment results can aid engineers in selecting the superior manufacturing process flow for a given product. To demonstrate usefulness of the information framework, a prototype desktop application has been developed. The application was implemented in Windows Project Foundation (WPF) using C# as the coding language to create a graphical user interface. Mathworks MATLAB serves as the calculation engine. Unit manufacturing process models follow the framework and are read by the application, which produces a sustainability assessment for the manufacturing process flow. A manufacturing process flow for an automobile-like metal product acts is used to demonstrate the software application.

Manufacturing taxonomies and accompanying metadata of manufacturing processes have been catalogued in both reference books and databases on-line. However, such information remains in a form that is uninformative to the various stages of the product life cycle, including the design phase and manufacturing-related activities. This challenge lies in the varying nature in how the data is captured and represented. In this paper, we explore measures for comparing manufacturing data with the goal of developing a capability-based similarity metric for manufacturing processes. To judge the effectiveness of these metrics, we apply permutations of them to 26 manufacturing process models, such as blow molding, die casting, and milling, that were created based on the ASTM E3012-16 standard. Furthermore, we provide directions towards the development of an aggregate similarity metric considering multiple capability features. In the future, this work will contribute to a broad vision of a manufacturing process model repository by helping ease decision-making for engineering design and planning.

Study Case

The increasing growth of human population together with the material consumption of most industrialised nations taking place at an unsustainable rate have been causing the degradation of the planet. The implementation of sustainable methodologies can contribute to the implementation of more ecological practices. A computational tool integrating ecodesign principles was developed to support sustainable decisions. This tool allows designers and clients to investigate and compare different solutions for each product, taking into account the whole product life cycle, as well to incorporate the product’s physical data with the CAD model. In this work a decision computational tool was used combined with the additive manufacturing study case. This system can contribute to a more sustainable manufacturing product development, facilitating the evaluation of the environmental impact analysis, optimization and comparison of the product life cycle.
