@inproceedings{265, 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.}}, author = {{Hinrichsen, Sven and Riediger, Daniel and Unrau, Alexander}}, booktitle = {{2017 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM)}}, isbn = {{978-1-5386-0948-4 }}, keywords = {{injection moulding, machine tools, maintenance engineering, productivity, projection-based assistance system, injection molding tools, assembly activities, assembly process, assembly errors, tool maintenance, disassembly activities, economic potential, Industrial Engineering Lab, Ostwestfalen-Lippe University of Applied Sciences, toolmaking, Tools, Injection molding, Maintenance engineering, Usability, Task analysis, Workstations, Morphology, assembly assistance systems, assistance systems, maintenance of injection molding tools, manual assembly}}, location = {{Singapore}}, number = {{1}}, pages = {{1571--1575}}, title = {{{Development of a Projection-Based Assistance System for Maintaining Injection Molding Tools}}}, doi = {{https://doi.org/10.1109/IEEM.2017.8290157}}, year = {{2017}}, } @inproceedings{432, abstract = {{The trend of increasing technological complexity of machines mainly correlates with the integration of additional functions in machines. Increasing functionality of the machines leads to an increased number of control elements, which limits the clarity of the machine operation and leads to higher cognitive demands in the machine operation. Due to the growing functional range of production machines the demand of usability for the operating systems continues to grow. The selection and design of icons for the identification of controls contributes significantly to usability, especially for intuitive operation of production machines. The aim of this study is to investigate the intuitive usability of production machines, to consider its use of graphical elements (icons) and to derive recommendations for a demand-oriented selection and design of icons. To achieve this goal, laboratory studies at five modern production machines (laser sintering machine, CNC universal lathe, plastic injection molding machine, laser processing machine, woodworking machine) - each with different operating concept - were performed. The results of the study show that the used symbols in the examined machines are only limited self-explanatory and intuitive, and thus have significant deficits for easy and intuitive operation. Especially the combination of screens and electronic keys or switches was often criticized and leads to uncertainty in the operation. As a result, recommendations for the design of icons on production machines are given. }}, author = {{Riediger, Daniel and Hinrichsen, Sven and Schlee, Alexander}}, booktitle = {{Production Engineering and Management}}, editor = {{Villmer, Franz-Josef and Padoano, Elio}}, isbn = {{978-3-941645-11-0}}, keywords = {{Usability, production mach ine, icons, usability, hum an-machine compatibility}}, location = {{Trieste}}, number = {{1}}, pages = {{123--130}}, publisher = {{Hochschule Ostwestfalen-Lippe}}, title = {{{Ergonomic Design of Graphical Control Elements on Production Machines}}}, year = {{2015}}, } @inproceedings{4330, abstract = {{Catchwords such as “Cyber-Physical-Systems” and “Industry 4.0” describe the current development of systems with embedded intelligence.
