Implementation of the Lean Model for Carrying out Value Stream Mapping and SMED in the Aerospace Engine Case Production

The lean manufacturing has been widely applied in the most of the industry sectors. Single Minute Exchange of Dies (SMED) is one of lean manufacturing tools that can be used to further reduce production waste. In order to ensure waste be effectively reduced, lean manufacturing has tools to achieve its goal. The first step is analysis of current state value stream map from the production line. The second step is the use of Single Minute Exchange of Dies to propose and carry out improvement actions in bottleneck process. In this study, the aerospace engine case production lead time was reduced from 9 weeks to 7 weeks by VSM method. The SMED method was applied to improve bottleneck's setup time from 95.68 minutes to 76.97 minutes. The lean manufacturing tool can help factory to reduce inventory in the WIP.
