Abstract

The tool setting process of a rotary draw-bending process is very complex. Only experienced machine operators know which settings lead to a good result in relation to the bending task. Up to seven individual tools can be installed, positioned and set in the process independently. A complete set of tools consists of: pressure die, mandrel, wiper die, inner and outer clamp die as well as the bend die and the collet. [2] Furthermore there are the axis settings, which can be adjusted with the parameters distance, force, angle, torque and time. If a defect occurs after the successful set-up process the machine operator has various possibilities to solve the problem. The effects of the different setting parameters and the procedure for the fastest possible elimination of the error are often unclear. The goal is to be able to use an adjustment support for the setting process by means of physical-analytical principles and systematically constructed FE simulations at the bending machine. In order to evaluate the bending result, the condition of the bending component is examined concerning the quality characteristics, cracking, wrinkling, cross-section deformation and elastic recovery. [1] Based on performed and analyzed FE simulations, adjustment recommendations regarding the respective quality characteristics are to be established as well as predictions about possible defects. The simulation and calculation results flow into a database. This is used for the implementation of an electronic expert, who uses a visualization aid to provide the machine operator with information and recommendations on the setup settings. This avoids errors during the equipping process and saves setup time. Machine operators and particularly trained staff are guided and supported in their work.

Abstract

The main objective of FIBRE4YARDS project is to maintain European global leadership in ship building and ship maintenance, through implementation of the Shipyard 4.0 concept in which advanced and innovative FRP manufacturing technologies are successfully introduced. This project has received funding from European Union's Horizon 2020 research and innovation programme under grant agreement n°101006860.

Abstract

TSI is currently, among other activities, developing and managing smart manufacturing in the framework of the FIBRE4YARDS project, which has as one of its main objectives to increase the production capacity of shipyards for ships made of composite materials through the implementation of highly automated methods and the implementation of Industry 4.0 technologies. Within the project, several demonstrators of different parts of a catamaran and a patrol boat will be built using new manufacturing processes that will have the industry 4.0 philosophy implemented. For this, TSI has designed and built 6 monitoring systems, one for each manufacturing process, and collaborated in the development of the IoT platform for the Shipyard4.0. The objective of TSI is to improve the knowledge of the state of the manufacturing processes and to visualise in real time the parameters of interest of the different manufacturing processes.

This research has been carried out in the framework of the FIBRE4YARDS project, composed of relevant stakeholders from the shipbuilding and FRP sectors. This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement no. 101006860.

Abstract

Since many modules of a ship cannot be practically reduced to a single structure, joining technologies are employed to join various
substructures and transfer loads between the different components. These joining methods include welding, mechanical fastening, adhesive bonding, overlamination, and hybrid joining. In the current study, a comprehensive review has been conducted on the mechanical performance of the common joining techniques in the marine industry.

Abstract

Aerospace industry is well known to be one of the most demanding sectors to work with. It is strongly normalized, monitored and audited on behalf of airworthiness. In this scenario, continuous improvement is a must, to comply not only with requirements, but also lead times and costs. TITANIA, one of most recognized materials testing labs working for aerospace, moved to a tailor-made integral management system to deal with the high volume of data they deliver to their customers. After a two years effort, now is exploiting its results by offering better lead time compliances, robust test reports and new data analysis services. Digital transformation has pushed TITANIA into Industry 4.0. This paper presents the followed methodology and the first results obtained.
