Metodologialean Manufacturing utilizada na redução de consumo de óleo hidráulico numa fábrica de usinagem no interior de Pernambuco: um estudo de caso

Abstract

In a highly competitive environment in the metallurgical sector, the constant search for improvements in transformation processes is a daily reality. In this context, the Lean Manufacturing (LM) methodology stands out as a crucial approach to achieving a state of operational perfection, requiring the elimination of waste. The objective of this work was to conduct a case study that illustrated the applicability of the Lean Manufacturing methodology in reducing hydraulic oil waste, proposing improvements in an automotive parts supply company located in the interior of Pernambuco. Within the Lean Manufacturing paradigm, which advocates cost reduction as one of the ways to increase profits, identifying failures is essential. Thus, the systematization of the research involved direct observation to diagnose the problem in question. Subsequently, the tools of the LM methodology were used, recognized for their effectiveness in solving industrial and everyday challenges. The process included analyzing the causes of the problem through techniques such as brainstorming, Ishikawa diagram with 6m's and the preparation of an A3 report. The goal was to direct corrective actions, with the help of Lean tools, to eliminate waste and improve production processes. The results revealed that the proposed solutions and the application of Lean tools were successful. There was a 60% reduction in hydraulic oil waste, indicating a substantial improvement in the company's processes. Furthermore, a notable development was observed in the team involved in the research. This success highlights the effectiveness of the Lean Manufacturing methodology in operational optimization and in promoting an organizational culture focused on efficiency and the elimination of waste.
