This research focuses on addressing the issue of low machine efficiency in the machining area of a metalworking company in Callao, Lima. It highlights the critical role of machinery availability, quality, and performance in the metalworking industry, particularly in machining processes that are essential for high-quality production. Low efficiency in this area contributes to decreased productivity and machine availability, increased rework, and higher operational costs, all of which impact the company's competitiveness. To tackle this challenge, the study proposes the application of Total Productive Maintenance (TPM) tools as a central strategy to improve the Overall Equipment Effectiveness (OEE) in the machining area. Additionally, the study suggests incorporating standardization practices and Industry 4.0 technologies. TPM is presented as a holistic approach to maximize machine efficiency, involve all personnel in maintenance efforts, and foster a culture of continuous improvement, ultimately enhancing productivity and reducing waste.
