69609 - A Reusable Unit Process Life Cycle Inventory Model for Infeed Centerless Grinding 

Environmental impact minimization is 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 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.
