Additive manufacturing in production: challenges and opportunities

Abstract: Additive manufacturing, characterized by its inherent layer by layer fabrication methodology has been coined by many as the latest revolution in the manufacturing industry. Due to its diversification of Materials, processes, system technology and applications, Additive Manufacturing has been synonymized with terminology such as Rapid prototyping, 3D printing, free-form fabrication, Additive Layer Manufacturing, etc. A huge media and public interest in the technology has led to an innovative attempt of exploring the technology for applications beyond the scope of the traditional engineering industry. Nevertheless, it is believed that a critical factor for the long-term success of Additive Manufacturing would be its ability to fulfill the requirements defined by the traditional manufacturing industry. A parallel development in market trends and product requirements has also lead to a wider scope of opportunities for Additive Manufacturing. The presented paper discusses some of the key challenges which are critical to ensure that Additive Manufacturing is truly accepted as a mainstream production technology in the industry. These challenges would highlight on various aspects of production such as product requirements, process management, data management, intellectual property, work flow management, quality assurance, resource planning, etc. In Addition, changing market trends such as product life cycle, mass customization, sustainability, environmental impact and localized production will form the foundation for the follow up discussion on the current limitations and the corresponding research opportunities. A discussion on ongoing research to address these challenges would include topics like process monitoring, design complexity, process standardization, multi-material and hybrid fabrication, new material development, etc.

Challenges for maintenance of PLC-software and its related hardware for automated production systems: Selected industrial Case Studies

Abstract: The specific challenges for maintenance of software and its related hardware for the domain of automated Production Systems is discussed. Presenting four industrial case studies from renowned and world market leading German machine and plant manufacturing companies, these challenges and different solution approaches are introduced with a focus on software architectures to support modularity as a basis for maintaining long-living automated Production Systems. Additionally, most critical aspects hindering classical approaches from software engineering to be successful, e.g., modes of operation and fault handling, are discussed. In the last decades, research in the field of software engineering for automated Production Systems (aPS) has been focusing on developing domain specific model-driven engineering approaches supporting the development process, but mostly neglecting the operation, maintenance and re-engineering aspects. However, the success of model-driven engineering in aPS industry has been limited because the effort to introduce model-driven engineering and to change the entire existing legacy software is estimated as too high and the benefit as too low against the background of customer specific solutions expecting a low degree of reuse.

Microstructure and mechanical characterisation of SLM processed Haynes® 230®

Abstract: Selective Laser Melting (SLM) enables the production of complex near-net-shaped parts especially out of difficult to machine Nickel based alloys like Haynes ® 230 ® . However, exact knowledge of the SLM processing windows and the corresponding mechanical properties is essential for a target-oriented part design as well as post process planning. Especially the high cooling rate of the small weld pool characterizes the SLM process and is known to cause material microstructures different to standard wrought or cast material. Samples are built with different heat input levels and are analysed for their density, poreand crack sizes. Optical and scanning electron microscope (SEM) and electron backscatter diffraction (EBSD) are used to characterize the material microstructure. Static tensile test samples were built in either 0° or 90° orientation for the evaluation of mechanical properties at room temperature and anisotropy as well as the influence of the different heat input levels are assessed. It is shown that the alloy itself is well suited for the SLM process allowing the consolidation of nearly defect free material with improved mechanical properties with regards of yield and ultimate tensile strength compared to cast as well as wrought material.

Autonomous Guided Vehicles: Methods and Models for Optimal Path Planning

Abstract: This book provides readers with extensive information on path planning optimization for both single and multiple Autonomous Guided Vehicles (AGVs), and discusses practical issues involved in advanced industrial applications of AGVs. After discussing previously published research in the field and highlighting the current gaps, it introduces new models developed by the authors with the goal of reducing costs and increasing productivity and effectiveness in the manufacturing industry. The new models address the increasing complexity of manufacturing networks, due for example to the adoption of flexible manufacturing systems that involve automated material handling systems, robots, numerically controlled machine tools, and automated inspection stations, while also considering the uncertainty and stochastic nature of automated equipment such as AGVs. The book discusses and provides solutions to important issues concerning the use of AGVs in the manufacturing industry, including material flow optimization with AGVs, programming manufacturing systems equipped with AGVs, reliability models, the reliability of AGVs, routing under uncertainty, and risks involved in AGV-based transportation. The clear style and straightforward descriptions of problems and their solutions make the book an excellent resource for graduate students. Moreover, thanks to its practice-oriented approach, the novelty of the findings and the contemporary topic it reports on, the book offers new stimulus for researchers and practitioners in the broad field of production engineering.

Engineering method for the integration of modules into fast evolving production systems in the process industry

Abstract: The reduction of the required effort for integration of a module into a production plant is the fundamental aim of modular plant architectures. An essential prerequisite for efficiency is to shift engineering efforts from the classical site-engineering to the engineering of plant modules. In such a scenario, the engineering of the entire system can be subdivided into two separate engineering phases, namely: a) the module supplier engineers and builds the module and b) the plant engineer uses the modules. This article presents an architecture that simplifies the integration of modules into production plants by using an information model — Module Type Package — for transferring and storing necessary engineering results during module-engineering.

The Adapter module: A building block for Self-Learning Production Systems

Abstract: The manufacturing companies of today have changed radically over the course of the last 20 years and this trend certainly will continue. The increasing demand and the intense competition in market sharing are radically changing the way production systems are designed and products are manufactured pushing, in this way, the emergence of new manufacturing technologies and/or paradigms. This scenario encourages manufacturing companies to invest in new and more integrated monitoring and control solutions in order to optimize more and more their production processes to enable a faster fault detection, reducing down-times during production while improving system performances and throughput along time. In accordance with these needs, the research done under the scope of Self-Learning Production Systems (SLPS) tries to enhance the control together with other manufacturing activities (e.g. energy saving, maintenance, lifecycle optimization, etc.). The key assumption is that the integration of context awareness and data mining techniques with traditional monitoring and control solutions will reduce maintenance problems, production line downtimes and manufacturing operational costs while guaranteeing a more efficient management of the manufacturing resources.

Implementing Manufacturing as a Service : A Pull-Driven Agent-Based Manufacturing Grid

Abstract: Presented at the 11th International Conference on ICT in Education, Research and Industrial Applications: Integration, Harmonization and Knowledge Transfer Lviv, Ukraine, May 14-16, 2015. Author supplied: Abstract. User requirements and low-cost small quantity production are new challenges for the modern manufacturing industry. This means that small batch sizes or even the manufacturing of one single product should be affordable. To make such a system cost-effective it should be capable to use the available production resources for many different products in parallel. This paper gives a description of the requirements and architecture of an end-user driven production system. The end-user communicates with the production system by a web interface, so this manufacturing system can be characterized in terms of cloud comput- ing as the implementation of manufacturing as a service, abbreviated to MaaS.

An Ontology-Based Smart Production Management System

Abstract: The evolution of manufacturing technologies has allowed for rapid prototype development and easy transfer of ideas from design to production, even in the convenience of the home office (via 3D printers). It has also created an unstable market environment. This situation calls for novel solutions in manufacturing that allow high adaptability and responsiveness. The use of smart, agent-based systems empowered by semantic technologies could provide the solution. The authors' ontology-based smart production system is based on the use of agents. They present both the system architecture and a framework for deployment under a living lab environment. They also give special focus to alleviating obstacles met in the small-series-like ramp-up of highly customized products, such as aircraft.

Analyzing the engineering effort for the commissioning of industrial automation systems

Abstract: In the industrial automation a paradigm shift from centralized, static automation structures to reconfigurable manufacturing systems (RMS) might be lie ahead. RMS are seen as a key enabler for the required changeability of future production companies since they can reduce the engineering effort needed for the reconfiguration of existing or the construction of new production systems. However, it is not clear how the companies can benefit from RMS in detail. For example, the reduction of engineering effort cannot be expressed in figures by today. But such information is necessary to convince the industry of the advantages of the new production principle. Indeed, existing RMS paradigms like Service-Oriented Architectures are rarely used in the practice of automation. The basis for analyzing the advantages of RMS is an analysis of the status quo in the industrial automation. Regarding the engineering effort of current automation systems, this paper will present a case study considering the effort occurring during the commissioning process of a production system constructed by state-of-the-art components. The evaluation of the study can serve as a reference when comparing the engineering effort of RMS with today's systems.

Laser Additive Manufacturing with Crack‐sensitive Materials

Abstract: Laser additive manufacturing is state-of-the-art and regarded as a key technology in the future of production engineering [1]. Originating from a computer model, a new freedom of design can be achieved by simply adding layer by layer. Beyond the new perspectives and extended possibilities of conventional processes there are fields of application which already have been opened up. One of those is the highly innovative but demanding field of processing with heat resisting alloys (see Fig. 1). This field of engineering has traditionally been a door opener for hightech technologies such as aerospace or energy [2, 3].
