By strategically grouping slot openings with similar cogging torque distribution patterns or displacing slot openings in opposite directions, the cogging torque can be reduced substantially. Additionally, the selection of specific stator-slot and rotor-pole combinations plays a crucial role in enhancing torque performances and minimizing cogging torque in axial-flux permanent magnet machines.What is definition of SMED in lean?

Single-Minute Exchange of Die (SMED) is a lean manufacturing tool designed to reduce the time it takes to switch from one production line or process to another to under ten minutes, hence the term "single-minute." This methodology aims to enhance production flexibility and efficiency by minimizing changeover times, allowing for a more responsive adaptation to customer demands and market changes. SMED achieves this by streamlining processes and eliminating non-value-added activities during changeovers. The essence of SMED lies in its structured approach to identifying and separating internal activities (those that can only be performed when the production process is stopped) and external activities (those that can be performed while the machine is running), with the goal of converting internal activities into external ones wherever possible. This conversion process is critical for reducing downtime and improving overall equipment effectiveness (OEE). Moreover, SMED supports the lean principle of continuous improvement by providing a systematic method for analyzing and optimizing setup tasks. This not only reduces setup time but also contributes to a leaner, more efficient production system capable of adapting quickly to changing production needs. The methodology's effectiveness in enhancing production flexibility and efficiency makes it a cornerstone of lean manufacturing practices, alongside other tools like 5S and continuous flow, to support economic sustainability and operational excellence. Research and case studies across various industries, including automotive and manufacturing, have demonstrated the practical benefits of SMED, including significant reductions in changeover time, increased machine utilization, and the facilitation of a more agile production environment. These improvements are not only beneficial for large enterprises but are also crucial for the sustainability and competitiveness of small and medium-sized enterprises (SMEs).What are the advantage of curriculum reform from OBE to SBE?

The milk-run method, as defined within the lean logistics framework, is a cyclic material delivery system designed to enhance the efficiency of transportation and supply chain operations. This system is characterized by its operation in a loop, delivering materials from a central point to various destinations, such as assembly stations within a manufacturing plant, and then returning to the starting point to repeat the process. The milk-run method can be divided into two main types: supplier milk-run and in-plant milk-run systems. The in-plant milk-run system, in particular, has gained attention with the advent of Industry 4.0, as it supports the delivery of materials from warehouses to assembly stations within the plant, often utilizing Autonomous Vehicles (AV) or Automated Guided Vehicles (AGV) for automated material handling. This method aligns with the lean logistics implementations, aiming to minimize waste and reduce costs by ensuring a pull-based material supply, which is dictated by the demands of manufacturing or assembly processes. The milk-run system supports the lean manufacturing principle of eliminating waste in material handling by standardizing the delivery process and optimizing the use of resources. Furthermore, the milk-run method contributes to the Just in Time (JIT) philosophy by facilitating the timely and efficient supply of components, thereby preventing shortages on assembly lines and minimizing the risk of production delays. The implementation of the milk-run method involves careful planning and optimization of routes and delivery schedules to ensure cost efficiency and meet the specific needs of the production system. This includes addressing challenges such as determining the optimal routes and periods for each delivery vehicle, managing buffer stock constraints at assembly stations, and accommodating the delivery of multiple commodities. Through these strategies, the milk-run method significantly contributes to the lean and efficient operation of manufacturing and assembly processes.Why is aluminium alloys best for automotive components?
