The contribution proposes the individuation of innovative methods for the design of systems-products in production through the use of virtual reality, from the interaction between the discipline of design and the technology in the manufacturing systems in constant evolving. Industry 4.0 represents the transformation through digital information systems that generate a productive and socioeconomic change and the level necessary to address the major contemporary competitive challenges. The new production paradigm a new level of human-machine interaction. The role of the person changes and takes on greater importance in the digitized factory through the contribution of Ergonomics, highlighting the centrality of design by the virtual ergonomics that allows the preliminary verification of the issues related to the postures of the operator of production during the working activities increasing the well-being. Virtual technologies and discipline of design anticipate new design experiences and multiple scenarios for the configuration of new products and services.
In current industrial systems, automation is a very important aspect for assessing manufacturing production performance related to working times, accuracy of operations and quality. In particular, the introduction of a robotic system in the working area should guarantee some improvements, such as risks reduction for human operators, better quality results and a speed increase for production processes. In this context, human action remains still necessary to carry out part of the subtasks, as in the case of composites assembly processes. This study aims at presenting a case study regarding the reorganization of the working activity carried out in workstation in which a composite fuselage panel is assembled in order to demonstrate, by means of simulation tool, that some of the advantages previously listed can be achieved also in aerospace industry. In particular, an entire working process for composite fuselage panel assembling will be simulated and analyzed in order to demonstrate and verify the applicability and effectiveness of human–robot interaction (HRI), focusing on working times and ergonomics and respecting the constraints imposed by standards ISO 10218 and ISO TS 15066. Results show the effectiveness of HRI both in terms of assembly performance, by reducing working times and ergonomics—for which the simulation provides a very low risk index.
The aim of the present paper is to propose innovative methods for ergonomic design of tools, equipment and manual tasks on workplaces of an automotive assembly line, in order to increase worker's welfare and system's performance by improving general safety conditions. The manufacturing industry is heading to the ever more pushed use of digital technologies in order to achieve very dynamic production environments and to be able to develop continuous process and product innovations to fit into the so called Fourth Industrial Revolution, also identified as Industry 4.0. The main goal of Industry 4.0 is to "re-think" factories through the use of digital, to reconsider the design approach and to monitor the production process in real time.The research addresses the evolution of industry 4.0 in relation to the discipline of "design", where the management of knowledge in the production process has led to the strengthening and improvement of tangible goods. Starting by current ergonomic analysis models and innovative approaches to the process design of industrial production line, the manufacturing processes in the virtual environment were defined and optimized with the use of innovative 3D visualization technologies. The constant interaction among the different disciplines of design, engineering and occupational medicine, enables the creation of advanced systems for simulating production processes based on virtual reality and augmented reality, mainly focused on the needs and requirements of the workers on a production line with the main objective of bringing out the interaction between real and virtual factory (Cyber-Physical System -CBS).The objective is to define new models of analysis, of development and of testing for the ergonomic configuration of processes, that improve and facilitate the human-machine interaction in a holistic view, in order to protect and enhance human capital, transferring the experiences and knowledge in the factory system, as key factors for the company and for the sustainability of workers welfare levels.
Automation plays a key role in the realisation of the Factory 4.0 and technological research, combined with the use of innovative materials, contributes to the improvement of products in terms of functional, technical and production quality. Within this context, the so-called Digital Twin allows to reproduce the real behaviour of a production system in a virtual environment, giving the possibility to numerically perform the desired analysis. Human-robot interaction (HRI) is increasing in those workplaces where the manual activity is not safe nor efficient in terms of performance (e.g. cycle time) and it is characterised by several levels of interaction (cooperation, collaboration and coexistence). The aim of this paper is to propose a numerical procedure that, based on the simulation, allows verifying the process feasibility, validating the interaction between human and robot and programming the logic controller to be implemented on the real robot. A case study about assembling of composite components of an aircraft fuselage panel is proposed. The use of the robot allows to speed up the processes of drilling and sealing, leaving to human less dangerous operations.
