Eco-Efficiency of CNC Manufacturing Processes
The manufacturing industry is a significant source of environmental burden worldwide, responsible for 20–30% of CO2 emissions. Life Cycle Assessment (LCA) analyses show that the key factor is the energy intensity of most technologies (Scope 2 according to ESG), with 37% of energy being consumed in manufacturing processes. To minimize negative environmental impacts, it is necessary to assess the impacts related to output products and improve the eco-efficiency of the entire process. The eco-efficiency of production depends on many factors, such as product design (material, geometry, lifespan, recyclability), energy efficiency of manufacturing machines, setting of production parameters, process organization, efficiency of auxiliary processes, and support functions. Examples show eco-efficiency improvements in parts such as the “Bracket” (58%) or the “Boom” (22%), including the “MCU” machine modification (28%), assessed according to ISO 14045. The RCMT aims to combine expertise in design, machine control, and process optimization to improve eco-efficiency and production economics.
