Implementing SMED Techniques to Decrease Setup Time for Gear Housing Machines.

Abstract

This article explores the implementation of the Single Minute Exchange of Dies (SMED) system to reduce equipment changeover times and optimize Computerized Numerical Control (CNC) machine production processes. SMED focuses on converting changeover steps to "external" activities, streamlining the remaining steps to achieve changeover times within single-digit minutes. The study emphasizes the practical applicability of SMED when combined with lean tools, facilitating successful implementation without significant investments. In the context of lean manufacturing, prioritizing continuous improvement and waste elimination, the paper underscores the economic significance of setup time reduction.The research specifically targets Vertical Machining Center (VMC) machines, aiming to reduce setup time by 30%. The methodology involves a meticulous analysis of actual changeover time, followed by applying SMED techniques for efficiency. Findings reveal a tangible reduction in setup time, from 4 hours to 3 hours and 10 minutes, notably in the "waiting" category of Muda (waste).The article highlights the originality and practical value of the study by showcasing actions to optimize CNC machine production through Lean Management, particularly the SMED method. Acknowledging spatial and temporal limitations, the paper suggests potential avenues for future research expansion. In summary, this work contributes to the discourse on efficiency enhancement in manufacturing processes, providing insights into the impactful utilization of SMED and Lean Management principles.
