  • 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...

  • Modeling hop kilning with respect to energy consumption and drying kinetics

    Creator:
    Thomas, Matthew W.
    Abstract:
    Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

  • 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 Information Modeling for Characterizing Sustainability Performance of Cyclic Manufacturing Processes

    Creator:
    Manoharan, Sriram
    Abstract:
    Sustainability has become an unprecedented priority in global manufacturing due to the growing concerns over issues such as an aging workforce, environmental degradation, and public health. The simultaneous consideration of the economic, environmental, and social aspects – often referred to as the “three pillars of sustainability” – is crucial to...

  • 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...

  • An Information Modeling Framework for Support of Sustainable Manufacturing System Design Decision Making

    Creator:
    Shankar Raman, Arvind
    Abstract:
    Manufacturing technology has continuously evolved and advanced over the past century; this has led to an increase in the production of consumer and industrial goods driven by simultaneous growth in population and wealth. Despite the resulting economic and labor growth, environmental impacts of manufacturing have increased dramatically due to the...

  • 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...
