  • A Techno-Economic Assessment Methodology for Advanced Additive and Joining Processes

    Creator:
    Malshe, Harsha A.
    Abstract:
    Integrated manufacturing systems, a combination of subtractive, additive, and joining processes, provide a competitive advantage for manufacturing organizations. As product designs become more complex and capital more scarce, an ideal combination of advanced manufacturing technologies (e.g., powder bed fusion or friction welding), in tandem with traditional subtractive manufacturing systems, can...

  • Characterization of Two Novel Machining Processes for Difficult to Machine Materials

    Creator:
    Doran, Michael P.
    Abstract:
    New materials with superior mechanical properties, such as increased strength and hardness, have been developed to allow for new and improved products. However, the mechanical properties that make these materials useful also makes them difficult to process using conventional methods. New machining processes need to be developed to generate products...

  • A Unit Manufacturing Process Characterization Methodology and Supporting Terminology for Sustainable Manufacturing Assessment

    Creator:
    Garretson, Ian C.
    Abstract:
    Manufacturing industry drives economic activity and growth around the world, but manufacturing activities consume large amounts of material, energy, and labor resources. Therefore, the impacts of manufacturing need to be accounted for and reduced. Direct benefits of manufacturing are products and income, which, in turn, influence the lives of people...

  • Process-based modeling for cradle-to-gate energy and carbon footprint reduction in product design

    Creator:
    Alsaffar, Ahmed J.
    Abstract:
    Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Life cycle energy consumption and carbon footprint are...

  • Stability and biological responses of zinc oxide metalworking nanofluids (ZnO MWnF™)

    Creator:
    Niyaghi, Faraz
    Abstract:
    Zinc oxide nanoparticles (ZnO NPs) have demonstrated the ability to improve lubrication and thermal conductivity, and stand as promising metalworking lubricant and coolant additives due to their low cost compared to other NPs. While nanomaterials are a focus of research due to their potential to enable advanced technologies, little is...

  • Integrating sustainable manufacturing assessment into decision making for a production work cell

    Creator:
    Zhang, Hao
    Abstract:
    Sustainability has been the focus of intense discussions over the past two decades, with topics around the entire product life cycle. In the manufacturing phase, research has been focused solely on environmental impact assessment or environmental impact and cost analysis in its assessment of sustainability. However, few efforts have investigated...

  • Enabling design for energy efficient additive manufacturing

    Creator:
    Nagarajan, Hari Prashanth Narayan
    Abstract:
    Manufacturing exists as a stronghold for continuous growth and development of economies, a trend that is likely to continue as the demand for commodities and products grow. Manufacturing drives innovation and productivity in developed nations, as well as promoting economic stability and development in developing nations. However, manufacturing activities pose...

  • Machining and toxicological performance of a zinc oxide metalworking nanofluid

    Creator:
    Sahakian, Misha
    Abstract:
    Lower production costs are a common goal of many manufacturers as part of their continuous improvement strategies. A large portion of production costs for manufacturers is the machining of metals to form components. Metal machining is accompanied by friction and heat which is dealt with using metalworking fluids such as...

  • Investigation of the environmental impact of wind energy and supplemental energy systems using a life cycle approach

    Creator:
    Prempreeda, Preedanood
    Abstract:
    Wind energy is a promising alternative energy source due to its environmental, economic, and social benefits and, as such, has garnered public support and government incentives for its development and implementation. With the growing number of wind parks in Oregon, a life cycle assessment (LCA) study for a representative new...
