With increasing complexity of machine tools, virtual commissioning (VC) has been established as an essential part of the engineering process. To describe all the different machine variants virtually, the sub-models of the machine modules must be...

Software sensors are becoming increasingly important in production and logistics, as they can solve complex measurement tasks and can merge measured variables from existing physical sensors. This article analyses and presents the potential for...

Industrial robots play a central role in the flexible automation of production systems. However, engineering such increasingly complex systems becomes more difficult by the use of specialized and often manufacturer-specific control and simulation...

Nowadays, the productivity of machining production processes is still significantly limited by dynamic process instabilities. An a priori determination of these limits enables a main time minimizing manufacturing process. However, conventional...

Cutting tests on steel are used to demonstrate the improved stability of a tapered roller bearing spindle compared to a conventional spindle using a new fast measuring method.

With direct trajectory generation on surfaces in numerical control (NC), the trajectory is generated by defining the free-form surface to be produced. The advantage is that there is no dicretization of the path during data transfer from Computer...

In this work, a machine learning model is trained on the basis of an autoencoder. The aim of the model is to recognise faulty cuts during laser cutting, as faulty cuts lead to high reject rates. The literature shows that it is possible to recognise...

Manufacturing of individualized products in small quantities combined with short innovation cycles poses challenges for production technology. Reconfigurable production systems with flexible functionality and technology can be part of the solution....

With the rising popularity of Open Platform Communications Unified Architecture (OPC UA) and Companion Specifications (CS), a universal understanding of OPC UA models becomes increasingly important. Thus, the OPC Foundation published a Best...

This paper introduces an innovative methodology for a chatter alert system that also enables the real-time utilization of simulated stability boundaries. Key components include the concurrent identification of cutting stiffness to enhance model...

The introduction of electromechanical power steering in passenger cars enables increased energy efficiency and thus follows the global trend of developing efficient machines and systems. An application-specific design of ball screws enables the...

Mobile robots enable the automated intralogistics of Industry 4.0. Prerequisite is a secure wireless connection to fleet managers or control systems . Private 5G campus networks with licensed frequencies are a promising solution. For this reason,...

This article presents a methodology for the near-real-time recording and documentation of greenhouse gas emissions in complex value creation networks. The methodology is conceptually based on relevant standards and approaches in the context of...

Twelve interviews were conducted with IT system users and providers to analyze the adaptability of IT systems in manufacturing companies. By methodically analyzing the interviews, it was possible to identify the factors that influence the duration...

The programming and control of robot systems lacks standardization, resulting in time-consuming and costly reprogramming by experts when boundary conditions change. To reduce the programming effort, a software framework for BPMN-based programming...

Efficient factory planning is becoming increasingly important in an ever more dynamic competitive environment. The automated generation of planning information from production data provides an approach to avoid errors in factory planning, accelerate...

The traceability of objects throughout their entire life cycle is an important prerequisite for the efficient management of circular value creation. To ensure this traceability with consistent data even in complex and dynamic value chains,...

The concept of circular value creation describes a sustainable economic system. However, it is currently challenging to extend the product life cycle so that products remain in the economic system long-term. Approaches are required to diagnose the...

In the context of this article, a method is presented on how to select a suitable assistive robot based on physical limitations. To achieve this, the body functions of a physically challenged person are compared with the requirements of an assembly...

The engineering tool CARA (Computer-Aided Risk Assessment) from the Fraunhofer Institute for Manufacturing Engineering and Automation IPA aims to ease the implementation of applications with human-robot collaboration in industry by simplifying and...

The article provides a brief summary of how machines can be integrated to ensure energy flexibility of companies, that means their ability to adapt quickly and process-efficiently to the energy market. The focus is on the „smart connector“, a...

Physically strenuous activities cause musculoskeletal complaints over time and prevent skilled labour access and retention. This article presents models and methods for digital ergonomics for the efficient and holistic planning of manual labour and...

Digitalization and sustainability are megatrends of the present and the future, with digitalization offering the chance to support the sustainability management of companies. The sustainability platform EcoHub allows for collecting corporate data...

This paper presents the development of an adaptable mold. The mold should be automatically adaptable to any geometry in order to produce fiber composite components cost-effectively. In the project, the mold is adapted by a robot. The robot adjusts...
