The Effectiveness of the Single Minute Exchange of Die (SMED) Technique for the Productivity Improvement

Abstract

The Single Minute Exchange of Die (SMED), a process-based innovation originally published in the mid-1980s, involves the separation and conversion of internal setup operations into external ones. Traditionally some of the manufacturing company facing the problem loss of available time due to spent time for the changeover processes. Changeover process time meaning changing the programming or operation sequences on the machine based on process requirement during the change from one to another one model especially for the mixing parts. SMED technique is a systematic approach that enables to reduce dramatically the set-up time or changeover time. Normally in the SMED technique, it was segregated between internal and external set-up. External set-up means any processing time was done up front which is before machine stop and internal time is any tasks was performed during machine in operating, which is considering changeover time. The impact to organization that it was increasing the productivity, capacity and at the same time increased the revenue. This paper focuses on the improving the productivity on the CNC machine process through implementing SMED technique and eliminating waste in the case study company.
