The paper presents the analysis of the machines efficiency use on the basis of an OEE coefficient for various periods of production for the company engaged in the manufacture of complex metal products. The Overall Equipment Effectiveness was assessed before and after changes improving the position of forming and after the implementation of the new shape of the forming matrix. With regard to the internal logistics companies it found that changes in addition to increase of the OEE (the result exceeds the value of the coefficient in relation to World Class) also affected on the production flow. It has been observed that proposed changes significantly improve the values of the TPM – availability, performance, and the quality indicators had more beneficial values.Keywords: OEE, production engineering, process flow, metal forming
