Abstract
This paper focuses on assessing manufacturing processes in an automotive component company using aspects of availability, performance efficiency, quality rate and sustainability to determine the overall progress achieved by implementing lean and green techniques. This action research aims to improve sustainability and manufacturing process efficiency simultaneously with appropriate corrective actions. Overall Environmental Equipment Effectiveness (OEEE) is calculated as the relationship between overall equipment effectiveness and environmental impact conducted by Domingo and Aguado. It means identifying losses due to sustainability and establishing a complete understanding of machine effectiveness and sustainability aspects of the production process. The manufacturing process consists of cutting, forging, CNC machining, robodrill machining, chamfering, broaching and removing burry, collected from primary (sampling data collection) and secondary data from the internals company. Based on the results, the OEEE value was “poor” in the forging process 55.752%, and the machining process 56.040%, due to low sustainability value. The corrective actions are to change the raw material from S45C to SWCH45K and recycle the waste. After improvements, the OEEE results on the forging process 60.118% and on the machining process 60.278%, can be declared “acceptable” because it meets the requirements of 60% < OEEE <70%
