Abstract
This study presents a life cycle assessment (LCA) of the SACE (Spark Assisted Chemical Engraving) micro-machining process for brittle materials, identifying opportunities to improve its environmental profile, focusing on greenhouse gas emissions. Key contributors to the environmental footprint, such as electricity consumption, system production, and chemical usage in the electrolyte solution, were evaluated. Electricity consumption during use has relatively low impact. A sensitivity analysis showed that variations in electricity consumption and location-based energy mixes have limited influence on the overall environmental profile. Production of the SACE system itself is a relatively important source of impacts. Production of electrolyte solution is also a potential source of impact. The study highlights that improving system design, material choices, and extending the system’s lifespan are critical to reducing the environmental impact. These findings provide direction for improving the environmental profile of the SACE machining system--and similar systems--with emphasis on reducing upstream production impacts, optimizing electrolyte choices, and enhancing system longevity.
