Quality Improvement In Manual Assembly By Software-Based Evaluation Of Human Misconduct
(European Safety and Reliability Association, 2019)
For reaching a level of high quality, production processes must be carried out both, economically and reliably. Despite automation and digitalization, manual assembly operations still constitute a key element for creating efficient production processes. However, in practice, creating robust and efficient manual assembly processes often fails because the occurrence of human errors cannot be quantified prospectively. Therefore, a corresponding procedure has been developed at the institutes of the authors. The module-based ...

Microstructural and Mechanical Properties of AISI 4140 Steel Processed by Electron Beam Powder Bed Fusion Analyzed Using Miniature Samples
(ASTM International, 2022-02-26)
The present study reports on the identification of an adequate process window for electron beam powder bed fusion (E-PBF) of AISI 4140 steel. For characterization, only miniature samples were used. It is clearly revealed that, for comparison and evaluation of different conditions, the use of such small samples is absolutely sufficient, even under fatigue loading. The initial E-PBF as-built condition is compared with conventionally heat-treated conditions (i.e., normalized as well as quenched and tempered). Based on ...
