Abstract [en]

This report constitutes the result of a master thesis that was composed at Presetting- and Sharpening at Scanias engine department in Södertälje. The department works as a service organisation for the production lines and its purpose is to maintain the right quality on tools within machining.

This is done by resharpening of drills and by turning and changing inserts on milling tools. The tools are then adjusted according to given tolerances to obtain correct quality on processed parts. The master thesis project consists of two main parts; analysis of flow and waste within the department with the goal to make the processes more efficient. The other part treats development of an assembly station for milling tools with the aim to improve the ergonomy. The mutual connection for the master thesis project lies within the ergonomy which has been a problem on the assembly station. The demands for the station has been developed mutually to ensure good ergonomy, flow and quality on the work performed on the station. In addition to this, a digitizing has been made of the department to illustrate the proposed changes.

Through observations, interviews and simulation of flow, wastes and bottlenecks have been detected. For the development of the assembly station the product development process Ulrich and Eppinger has been used.

The work resulted in a recommendation to institute routines and standardized work methods for how the work is supposed to be performed by operators. A routine should also be instituted on the milling handling station that means that the automatic measurement station always is prioritized by operators to guarantee maximum productivity. Finally, the wash process should be prioritized as a critical part in the daily work and thereby receive machine ownership, and thus make sure that knowledge about the wash process is obtained. The development of the assembly station led to three level based solutions that were supposed to be implemented today, within 1-2 years and a vision about the future's possible assembly station.
