Kapacitetsmätning av ett system för automatisk materialhantering

Sammanfattning: In order to be competitive in today’s manufacturing industry, companies are required to constantly improve the performance of processes and optimize the use of resources. It is therefore important to get a good view of the conditions in a production plant. The purpose of this work is to evaluate and document the effectiveness and degree of resource utilization in the Engcon FMS-plant (Flexible Manufacturing System). The aim is also to identify possible improvements. A well-established procedure to determine the efficiency of a process is the so-called Overall Equipment Effectiveness (OEE) method. With deeper knowledge thanks to the preparations, consisting of literature research and some research at the production plant, the practical part of this work started. The main source of information was the Fastems software that controls and plans production.  The rest of the information was provided by Henrik Mäki at Engcon and Emil Martinsson at Strömsunds Kvalitetslego. Some manual measurements were also required. All gathered information was examined and compiled before the calculation work began. Results show an OEE-value of 89,6 %, which is a high number indicating  an efficient plant usage. Despite of the high OEE-value, there is still room for improvements. At the start and finish of an EC206, order the machining process is slightly inefficient, but this could be prevented by adding a larger variety of machining programs. This would decrease milling time, but the benefits and drawbacks of such a measure have to be analysed before implementation. In order to get an accurate result, easily analysed data have to be used. The information behind the OEE-value in this report was a bit hard to interpret at some times but I do not think it has affected the result too much.
