Its core objective is to drastically reduce the time required to change over tooling and equipment, thereby minimizing downtime and enabling smaller, more frequent production runs. This enhanced agility directly contributes to improved responsiveness to customer demands, reduced inventory levels, and increased overall equipment effectiveness. SMED achieves these benefits by systematically analyzing and optimizing the changeover process, converting internal setup tasks (those that require the machine to be stopped) into external setup tasks (those that can be performed while the machine is still running).
-
Separation of Internal and External Setup
This initial step involves meticulously analyzing the current changeover process and identifying which tasks must be performed while the machine is stopped (internal setup) and which can be done while the machine is operating (external setup). Examples include pre-staging tools and materials, pre-heating dies, and performing necessary adjustments outside of the machine’s operational cycle. This separation lays the groundwork for maximizing the amount of setup work that can be completed concurrently with production, minimizing machine downtime.
-
Convert Internal Setup to External Setup
Once internal and external setup tasks are identified, the focus shifts to converting as many internal tasks as possible to external tasks. This might involve redesigning tooling fixtures for quicker installation, implementing standardized procedures for material handling, or utilizing quick-change clamping systems. Each conversion reduces the time the machine sits idle during changeover, directly contributing to increased production capacity and improved efficiency.
-
Streamline all aspects of the Setup Operation
This phase involves optimizing both internal and external setup tasks to minimize their duration. Techniques include standardizing procedures, utilizing specialized tooling, and implementing visual aids. Examples might include using color-coded labels for tools and dies, creating checklists for setup procedures, and employing ergonomic principles to streamline movements and minimize operator fatigue. These optimizations further reduce changeover time and contribute to improved overall efficiency.
-
Eliminate Adjustments
The final step involves eliminating the need for adjustments altogether, aiming for a truly “no-touch” changeover process. This can be achieved through techniques such as precise tooling design, automated adjustments, and improved process control. By eliminating adjustments, the risk of errors is minimized, changeover time is further reduced, and the consistency and quality of output are improved. This pursuit of perfection represents the ultimate goal of SMED and its contribution to maximizing machine shop efficiency.
By systematically implementing these four facets of SMED, machine shops can significantly reduce changeover times, enabling smaller batch sizes, improved responsiveness to customer demands, and reduced inventory levels. This, in turn, contributes to enhanced overall equipment effectiveness and improved profitability, aligning directly with the core principles of Kaizen and the pursuit of continuous improvement within the machine shop environment. SMED, therefore, constitutes a powerful tool within the arsenal of best Kaizen ideas for optimizing machine shop operations.
