The Reduction of Machine Changeover Time by Using the SMED Method

Abstract

The main purpose of the article was the reduction of the machine changeover time in practical terms, on the example of a forming machine in the production process of a trunk shelf, based on the use of the SMED method. The article presented the stages of development and the foundations of the lean management concept. The description of the SMED methodology was made. A forming machine was selected in the manufacturing process of a trunk shelf. The identification and measurement of changeover times in the real model were performed. Two alternative models were proposed. The first of them was made based on the division of activities into external and internal, and the delegation of external activities to be performed by the production staff. The second alternative model included investments. The proposed and implemented improvement actions brought benefits in a reduction of the changeover time of the tested machine.
