Grinding is a widely used process in many industries due to the precise geometric tolerances and excellent surface finishes it can offer, which makes it very useful when high quality parts have to be manufactured. Due to the wear that the grinding wheel suffers, a process known as dressing is periodically carried out to recover the cutting ability of the wheel. Dressing is an extremely important part of the grinding process, as it can alter and improve the cutting conditions of the wheel.During the dressing of vitrified bonded CBN wheels, the real dressing depth of cut is significantly lower than the theoretical depth of cut, leading to dimensional errors in the dressed grinding wheel, which consequently translate into the ground part. However, while deformations during grinding have been widely studied, this phenomenon has not been yet analyzed during dressing. Therefore, the main objective of this work is to determine the influence of the dressing parameters on the real depth of cut. Also, the effect of dresser wear and the deformations has been determined separately.To this end, a new methodology has been developed to measure the real depth of cut using a laser displacement sensor. Moreover, experimental tests have been carried out to characterize the influence that the dressing speed ratio (q d ) and set depth of cut (a d_set ) have on the actual depth of cut (a d_real ). It has been seen that the use of negative q d results in a more accurate real depth of cut, and therefore a more efficient dressing process. While the error using negative q d is about 10 %, using positive q d is about 25 %.

Industry 5.0 arises as a logical advance of Industry 4.0 to enhance the values that were being gradually abandoned due to the rapid technological advancement. These values focus on the human being, the sustainability and the continuity of the industrial system become the main objectives to be maintained during the development of the new smart industry model. These objectives allow the design of work environments within Industry 5.0 that ensure the adaptation of workers to technologies of Industry 4.0, in a sustainable way and that strengthen a resilient industrial system. In the present work the use of Value Sensitive Design (VSD) methodology for the redesign of manufacturing workplace in accordance with the values established by the Industry 5.0 is proposed. In this process, the VSD tripartite methodology allows to maintain the values of Industry 5.0 throughout the design process. Moreover, the integration of this methodology with the Axiomatic Design (AD) allows to achieve specific design parameters that meet the needs of the different stakeholders. The application of this model seeks the development of symbiotic work environments, in which workers increase their different physical, sensory and cognitive abilities with advanced technologies. The design of a work environment following the proposed model promotes a social smart industrial environment in which the safety and health of workers is ensured.

In today’s society, technology dominates most areas of human life. In particular, video games play an important role and manufacturing companies do not stop innovating to present their interactivity and playability through the hardware they introduce in the market. To be competitive in this sector it is necessary to innovate from the early stages of design to obtain products that are totally innovative in their form and interactivity but that do not cause difficulties in the subsequent manufacturing phase. By applying emotional design methodologies we will be able to establish requirements and design specifications necessary to present innovative controls to the market and facilitate the subsequent manufacturing processes. This method will be applied considering the haptic part of the controller, mainly the enveloping part, to define its characteristics, from the manufacturing point of view, to obtain an innovative product that connects with the emotions and sensations of the end user, including new functionalities in the market. To design the external part of the controller through the proposed methodology for the design of the external surfaces, also for the grips, ergonomics will be taken into account.

On traditional manufacturing systems such as machine tools (MTs), the increase on their operational capacity goes hand in hand with the improvement of its efficiency and accuracy. To do that, there are two types of verification methods, direct and indirect methods. The main aim of this job is to develop a test part to machine that allows determine the influence of the geometric errors of a three linear axes MT using volumetric and geometric methods. When the test part is machined, all axes of the machine are moved simultaneously. So, the difference between machined and test part design are, among others, the results of MT geometric errors. These errors can be reduced using volumetric verification techniques and MT compensation. Moreover, a proper test part design provides a work piece than can be used as a reference artefact for MT calibration. Nominal data of the test part can be obtained using a coordinate measurement machine. So, if the MT measures the machined test part using a probe, the difference between real and nominal coordinates could be used to obtain MT geometric errors. Therefore, the test part has to be designed to allow an easy data capture of the MT; taking into consideration the different kinematic models used to improve its accuracy. The new test part developed consist of a rectangular block with grooves and battlements on its external faces and an internal pyramidal structure. In addition, a series of conical holes are strategically located along the surface to improve data capture and errors identification. Synthetic tests show that this test-part design provides good results using volumetric and geometric techniques.

Despite environmental general conscience, heavy use of paper is still one fact in nowadays factories. The shorter the manufacturing production, the greater the tendency to employ paper to support quality tracking of pieces; using it to register measurements or nonconformities. This tendency increases drastically in some manufactures like aerospace, where typical production ratios vary between 9 and 18 subassemblies per month. The current work presents an automatic speech recognition system, meant to replace paper by a digitalized version of the manual writing task. The work presents (i) industrial use cases with benefits and requirements; (ii) the system architecture, including several tested free Automatic Speech Recognition modules, their analysis; and (iii) some open-source supporting modules that improves its functionality. The work concludes presenting several tests, showing the system performance against different kind of industrial noises, low to high quality microphones and users with different dialects.

Human needs and motivations depend on the person, on different generations, and on the life cycle period with its past experiences and future expectations. Moreover, the technological development goes along the organizational and human factor development leading to changes in the way of working of past and actual environments. Therefore, how the technologies of the fourth industrial revolution are impacting the human needs and the organizational development is a challenging research and practical gap. Therefore, the research question is how to integrate the human factor in the future organizational environment of the fifth industrial revolution. The paper presents an analysis of different areas impacting the challenge such as: human needs theories, management and leadership development, organizational development along the industrial revolutions, as well as the evolution of the different human generations towards a preliminary evolutionary model based on human needs. Moreover, other factors are analyzed such as the needs of human beings in the environment of influence of the organization as well as the life cycle of the human factor. Furthermore, the paper analyzes the human-machine interaction in different horizons from strategic to operative associated with Industry 4.0 technologies impacting the organizational sustainability and human well-being. For that purpose, a Human Digital Twin (HDT) model is developed with different levels influencing the human decision-making process with the goal to serve the human being to open new ways of working. To sum-up, the analysis and conceptual model presented serve as basis to derive future course of actions at the individual as well as in the organizational level based on the prediction and analysis of potential scenarios with their own risks and opportunities considering the human factor as an active element within the organization supporting new ways of working by considering the dynamic needs and motivations of the interacting agents.

The Forming Limit Curve (FLC) shows the limit combinations of principal strains on the sheet surface that can be successfully achieved before necking appears. Above the FLC, Atkins in 1996 proposed the existence of an unstable region where localized necking develops before reaching at the Fracture Forming Limit (FFL). Only the methodology for the evaluation of the FLC is covered in an international standard ISO 12004-2, where the basis of the tests consists of stretching of a previously clamped sheet blank over a Marciniak or Nakazima punch, providing an almost linear strain path in the sheet surface of the specimen. On the contrary, in single-point incremental forming (SPIF) processes, the hemispherical-shaped tools usually employed are relatively small compared to the general dimension of the specimen, producing a highly nonlinear strain path derived from both the incremental nature of the process and the severe curvature imposed by the small radii of the punches used in the forming process.Many authors have observed fracture strains in SPIFed samples well above the FFL obtained with Nakazima tests under the ISO 12004-2 standard. At the macroscopic level, the reason for this behaviour has been explained mainly based on the effect of bending and the difference in the stress triaxiality level, among others. This research analyzes the initiation of ductile fracture in Nakazima and SPIF specimens under a scanning electron microscope to elucidate the reasons of those differences at the microscopic level.

Product data management is the practice of assimilating, processing, protecting, and storing product data. One of the main concepts of Industry 4.0 is the application of data-driven policies to optimise industrial processes and monitor product life cycles. Consequently, a data management discipline within an organisation has become increasingly prioritised to address significant challenges such as data silos, security risks and general decision-making bottlenecks. The application of digital transformation technologies is needed to capture data from various industrial operations and product status in a smarter way. In addition, the data that is collected can be very useful in the maintenance phase of a product; in fact, it allows us to know the 'history' of the product under consideration, thus making risk factors understandable and giving us the possibility of defining intervention methods well in advance. The implementation of Blockchain (BC) technology in the storage of data that can be used for the maintenance of a product, can be seen as a solution to the problems behind the management of product data, in fact, it allows the acquisition, storage and processing of these in a secure, transparent, and decentralised environment. The present work in this regard studies the effects of BC on the performance of a product data management system in the maintenance process. The main critical issues in maintenance data management were identified and the potential of using blockchain technology was studied. A framework was developed to reproduce the operation of a BC for maintenance data management, and a set of key performance indicators (KPIs) were outlined to assess the effects of BC on the performance of a product data management system in the maintenance process. The results demonstrate that it is possible to improve a company's performance and make it more resilient through the collection of data within the BC, as it allows in-depth analysis during product maintenance planning and provides decision-makers with a single source of truth and insight to make complex decisions.

The industrial manufacturing systems are increasing in complexity to market changes. One of the best challenges of this complex systems is reach the schedule production baches without unexpected failures, looking for the zero defects. The presence of Multistage Machines (MSM) at industrial manufacturing systems allow to produce big batches in very short times. Nevertheless, these types of machines normally are manufactured as an ad hoc machine and have not maintenance strategies tested for preventive or predictive actions. Also, if a component of this machine fails, the entire machine fails, causing the loss of the production batch. Recent publications have developed local preventive and predictive maintenance strategies for industrial multistage machines, as an individual machines with local work conditions in different places. Nevertheless, the accumulated knowledge of a MSM cannot be used as relevant information to improve maintenance actions in other MSM. This research develops and proposes a network system, called Master Maintenance Management (MMM) to establish a continuous connection with all MSM, working as a datalogger who collects all relevant information for all MSM and suggest maintenance warning predictive and preventive warnings for machines and use them for preventive actions in the rest of each MSM working at the same conditions. So, the capability of one machine for take a local predictive action is performed by the MMM to take a preventive action in the other machines connected to the same network. This approach has been developed with thermoforming multistage machines, who have local preventive maintenance strategy based on individual maintenance times and predictive maintenance strategy based on some distributed sensors in the machine and a behaviour algorithm, called Digital Behaviour Twin (DBT). The most relevant benefits of this approach are the limitation of unexpected failures in the connected machines by using accumulated information of other MSM, the change of the predictive actions to preventive actions, and the machine perform by design changes suggested with all the database collected.

Professional diving is an occupation that includes a wide spectrum of different activities, but with the same common denominator: its performance underwater. It is carried out in both fresh and salt waters and encompasses such disparate tasks that professional diving is currently present in numerous productive sectors: hydrocarbon extraction, offshore platforms, port maintenance, public works, civil engineering, infrastructure hydraulic, power plants (hydroelectric, thermal and nuclear), shipbuilding, underwater construction, aquaculture, ship and boat salvage, NDT filming and reporting, teaching and training, and scientific research (geological, biological, archaeological, etc.). It is also characterized by being one of the most dangerous professions and presenting very specific risks, derived from the workplace in a hyperbaric environment, combined with to other hazards of the work activity similar to those of the ground workers. The objective of this study is to analyse procedural models based on the UNE_EN_ISO 45001:2018 Standard, applied to the execution of thermal cutting and underwater welding works. In order to carry out this work safely and in the most effective way, it must be systematically analysed, generating procedures and work instructions based on the tasks considered critical, and essential knowledge for all personnel who perform them. Such procedures and instructions should be based on a systematic analysis of the steps taken to perform each task, including the risks involved and the safety measures to be taken to control, reduce or, where appropriate, eliminate them.
