This study evaluates the environmental performance of two CNC machining strategies-three-axis and five-axis milling-used in the production of an aluminum wheel upright for a Formula Student vehicle. A process-based gate-to-gate Life Cycle Assessment (LCA) was carried out using Sphera GaBi software and the Ecoinvent 3.9.1 database, focusing exclusively on impacts associated with the manufacturing technologies. The analysis included detailed measurements of electricity consumption, machine time, machining operation ...

This study focuses on the structural and material optimization of a composite airbox for a Formula Student vehicle from the perspective of Life Cycle Assessment (LCA). Three evolutionary airbox generations are analyzed, each differing in geometry, number of parts, and material configuration, while maintaining the same primary manufacturing technology, in which the core structural material is a carbon fiber prepreg cured in an autoclave. The design optimization includes shell geometry simplification, integration of...
