Proposal for Streamlining the CNC Machine Changeover Process Through the Application of the SMED Method

Abstract In today’s highly competitive business environment, enhancing the efficiency of manufacturing processes is of critical importance. This research focuses on the application of the SMED methodology to increase the efficiency of the changeover process of a CNC machining center. The core of the study is a detailed analysis of the current state of production and changeover procedures on a selected machine. The process was monitored using video analysis of work operations. Based on this analysis, internal and external changeover activities were identified, and by eliminating inefficient steps, a set of improvement measures was proposed. As a result, a standardized changeover procedure was developed to optimize the overall process duration and improving maintenance systems. The final part of the study presents the outcomes of the improvement, expressed through reduced changeover time, along with a proposed economic evaluation of the implemented optimization measures.
