  abstract     = {{n the last years, Additive Manufacturing, thanks to its capability of continuous improvements in performance and cost-efficiency, was able to partly replace and redefine well-established manufacturing processes. This research is based on the idea to achieve great cost and operational benefits especially in the field of tool making for injection molding by combining traditional and additive manufacturing in one process chain. Special attention is given to the surface quality in terms of surface roughness and its optimization directly in the Selective Laser Melting process. This article presents the possibility for a remelting process of the SLM parts as a way to optimize the surfaces of the produced parts. The influence of laser remelting on the surface roughness of the parts is analyzed while varying machine parameters like laser power and scan settings. Laser remelting with optimized parameter settings considerably improves the surface quality of SLM parts and is a great starting point for further post-processing techniques, which require a low initial value of surface roughness.}},

  abstract     = {{Additive Manufacturing has arisen as a ground-breaking set of technologies that, thanks to their capability of continuous improvements in performance and cost-efficiency, was able in the last years to replace well-established manufacturing processes. Proficiency in the fabrication of highly complex parts forced this astonishing development. This research is based on the idea that through the integration of additive and conventional manufacturing technologies it is possible to achieve great cost and operational benefits especially in the field of tool making for injection molding. Such an integrated manufacturing solution could overcome the limitations of independent additive, subtractive, and post-processing procedures by strengthening their potentialities. The present study highlights the opportunities of a synergy between the above-mentioned manufacturing technologies for the optimized fabrication of injection molds. An additive manufacturing process chain is presented, and special attention is given to the surface quality and its optimization directly in the Selective Laser Melting process. The potentialities of the Laser Surface Re-melting technique are analyzed, and the process optimization leads to a reduction of 45% of the average roughness directly in the SLM process.

  abstract     = {{The maintenance of a tool for injection molding or forming is usually accompanied by its disassembly and assembly. The duration of the assembly activities is often a large part of the total activity time for the maintenance of the tool. The degree of performance of the employees in the execution of these disassembly and assembly activities is often low. In addition, allowances occur (e.g. searching for work equipment). At the Industrial Engineering Lab of the Ostwestfalen-Lippe University of Applied Sciences, a prototype of an assistance system was developed to support the assembly activities in toolmaking. With the help of this system, the operator is guided step by step through the assembly process. The economic potential of the system exists in the reduction of training times, the avoidance of assembly errors and the increase of labor productivity.}},
