Productivity Analysis in a Machining Workshop Through the OEE Evaluation of Machine- Tools

Abstract

This study evaluated the productivity of a machining workshop by analyzing the Overall Equipment Effectiveness (OEE) of machine tools, integrating availability, performance, and quality metrics. Optimizing production processes in a competitive environment is important to maintaining high-quality standards and meeting delivery deadlines. The research began with collecting operational and economic data, analyzing downtime and defects, and implementing strategic improvements based on Kaizen principles. Initial findings showed that the lathe and milling machine had OEE values below the optimal range, leading to production inefficiencies and bottlenecks. However, after implementing corrective actions, such as employee training, integration of digital measuring instruments, and acquiring a second lathe machine for the turning process, OEE significantly improved, exceeding 85 % for both machines. These results demonstrate that continuous improvement strategies enhance productivity, reduce production costs, and ensure high-quality machining processes.
