<p style="text-align: justify">Environmental impact minimization is&nbsp;an important aspect for improving the sustainability performance of manufacturing processes. Quantifying the environmental impacts of unit manufacturing processes requires systematic modeling of process life cycle inventories. Developing parametric models that relate product and process parameters are essential for identifying potential process improvements. This paper develops an inventory model for infeed centerless grinding based on the unit process life cycle inventory methodology. The developed&nbsp;unit process life cycle inventory model enables estimation of energy consumption, material losses, and fluid consumable, for a typical high-volume production setup. The unit process life cycle inventory model also includes supporting processes and operations in production environments, including machine tool setup, material handling, dressing of the regulating and grinding wheels. One of the primary goals of this paper is to develop an inventory model that can be easily applied to existing production lines. Therefore, the developed model estimates process consumption data from parameters directly used for process setup as well as machine and tool specifications that can be easily obtained from technical documentation and product geometrical specification. The developed model is demonstrated using a case study involving the infeed centerless grinding of an Inconel 718 cylindrical shaft on a Cincinnati Twin-Grip Centerless Grinding Machine.</p>

ASME 2021 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference (IDETC/CIE2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
