Maskinutnyttjande och ställtidsreduktion i en tillverkande industri

Sammanfattning

The report describes a field study conducted at an enterprise, where the company's machine manufacturing was examined with the aim of reviewing current production capacity and presenting theoretical improvement measures using production engineering methods. Various work measurements revealed problematic work practices that were unnecessarily time-consuming, where setup times were highlighted as a cause. Time and frequency studies were conducted to clarify the work process and thus the potential for improvement. A SMED analysis was performed to reduce setup times and create manufacturing capacity. The study clarified a work process with a strong lack of setup routines and work standards. The report proposes a standardized work process as well as a reduction in setup time during setup, in addition to underlying causes of capacity losses resulting from, among other things, poor supervision and material handling. Overall, the work is considered to have high reliability and validity thanks to the use of industry-tested methods that have generated several improvement measures.
