Article
Full-text available
Cryogenic machining is considered as the most sustainable alternative to conventional flood-cooled, near-dry and dry machining approaches in machining processes. This paper presents the application of a sustainability evaluation methodology for manufacturing processes, focusing on cryogenic machining processes. The methodology used here involves a...
Chapter
Conventionally, corporations focused on economic value creation for shareholders. However, sustainable business practices require considering sustainable value added to all stakeholders. The overall sustainable value added can be evaluated by measuring economic, environmental, and societal values created for all the stakeholders. While economic val...
Article
In-process cryogenic cooling has been credited with more precise products and enhanced integrity of machined surfaces. Enhanced surface integrity properties include smoother and more precise surfaces, grain refinement, and increase in surface hardness. This paper reports on the effect of liquid nitrogen (LN) cryogenic cooling and cutting parameters...
Article
Full-text available
Surface and subsurface characteristics of structural components, depending on the functions and their usage in service, can the critical aspect from service life viewpoint. Generated surface and subsurface characteristics of manufactured components affect wear, corrosion and fatigue resistance, and consequently determine safe-life of components tha...
Article
Full-text available
Cryogenic machining process, due to increased demand on environmentally-friendly manufacturing processes, has been gaining growing interest in the machining community. This paper presents an overview of cryogenic machining and its induced surface integrity characteristics such as surface roughness, topography, grain refinement and machining-induced...
Article
Full-text available
The goal of a number of many recent studies is to assess the potential of cryogenic cooling in improving the sustainability of manufacturing processes. One prime interest is the enhancement of surface integrity properties of newly machined surfaces. In this paper, we study the effect of liquid nitrogen cryogenic cooling on the surface integrity of...
Conference Paper
Unsatisfactory corrosion resistance is one of the major disadvantages of magnesium alloys that impede their wide application. Microstructural changes, especially grain sizes, of Mg alloys have significant influence on their corrosion resistance. Cryogenic machining was reported to effectively induce grain refinement on Mg alloys and has a potential...
Conference Paper
Full-text available
In recent years, the use of basic principles of sustainability science and engineering in new product development has been an emerging trend in manufacturing. Designing sustainable products and developing sustainable manufacturing processes have been a major research focus in sustainable manufacturing. This paper summarizes recent advances in manuf...
Article
Full-text available
Modern manufacturing processes continue to demand high quality products and processes at reduced costs and with greater environmental compliance. This has led to a critical consideration of the use of conventional cutting fluids used in most machining processes. Continued use of cutting fluids poses major problems as they they are hazardous for the...
Chapter
Results from a preliminary investigation of a drilling process using a metrics-based sustainability assessment method are presented in this paper. The proposed metrics aim at addressing the impacts of a manufacturing process, from the economical, environmental and societal points of view. This study includes a total-life-cycle approach for all iden...
Chapter
The paper presents a new methodology for generating the five-level Product Sustainability Index (ProdSI) based on a set of product sustainability metrics. The evaluation method includes processes of data normalization, weighting and aggregation. Data normalization is applied to convert measured physical data into dimensionless scores that each metr...
Chapter
Full-text available
This paper presents a framework for developing comprehensive product and process metrics for sustainable manufacturing, using machined products and machining processes examples, and addressing all three aspects of the triple bottom line – environment, economy and society. The need for developing standardized metrics is discussed for the wider use o...
Chapter
Supply chains are networks of companies engaged in activities required to bring a product (or service) to market. The design of products, processes and systems in sustainable supply chains (SSCs) must not only seek economic benefits for shareholders and value for customers but also manage environmental and societal impacts affecting all stakeholder...
