This paper presents the experimental work developed to measure the learning process through concept map analysis. The development of a concept map is requested by the students for each chapter or theme of the subject. As a result, maps from engineering courses have been analyzed. The measurements carried out consider several parameters, such as ind...

This paper presents a case study on the development of reconfigurable and lightweight fixtures for aircraft assembly, which are essential for modernizing and automating tooling fixtures in the aeronautical industry. Our study utilizes generative engineering and other design techniques to optimize performance and meet design objectives. Generative e...

This contribution discusses the lack of modernization and automation in the tools used for assembling structures in the aeronautical industry, which is a disadvantage for the Basque industry's competitiveness. The paper suggests that significant innovation in these tools will result in savings in their development and subsequent maintenance during...

Riveting is the most important method for joining two sheets of different materials. In order to promote electromagnetic pulse riveting (EMR), the influence of the impact velocity will be studied in this paper in order to correctly model the electromagnetic field of the riveting process. There are many parameters associated to the riveting process,...

Aircraft manufacturing companies often need to fabricate small amounts of sheet metal parts, as small batches, spare parts or for the design phase of larger batches, in order to shorten the ramp up to production. The materials used by the sector are lightweight and high resistance alloys and their forming requires heat assistance, to increase their...

Fastening is a recurrent assembly operation at the aerospace industry. Among the many different types of fasteners being used blind ones offer particular advantages but there is yet a lack of reliable installation monitoring methods for their massive adoption. The present paper proposes an installation evaluation solution for blind fasteners that i...

The experimental characterization of the material under shear loading is essential for researchers to study the plastic behavior of materials during manufacturing processes. Indeed, regardless of the loading mode, ductile materials mainly deform plastically under shear loading. Thus, for such material behavior analysis, shear tests are very useful....

Abstract The use of lightweight materials such as high-strength steel, aluminum alloys, and composites is increasing. The joints of dissimilar alloys as the aluminum alloy 6082-T6 and the HC420LA steel are studied in this work. The selected joining process is the magnetic pulse welding (MPW) which enables welding of these two alloys, being non-joi...

Wire Arc Additive Manufacturing (WAAM) is one of the most appropriate additive manufacturing techniques for producing large-scale metal components with a high deposition rate and low cost. Recently, the manufacture of nickel-based alloy (IN718) using WAAM technology has received increased attention due to its wide application in industry. However,...

Materials undergo various loading conditions during different manufacturing processes, including varying strain rates and temperatures. Research has shown that the deformation of metals and alloys during manufacturing processes such as metal forming, machining, and friction stir welding (FSW), can reach a strain rate ranging from 10⁻¹ to 10⁶ s⁻¹. H...

After some years of practice, common misunderstandings and lack of conceptual organization/structure have found from the learning results of Industrial Drawing students. This article presents an experimental work developed in order to measure the learning process through the concept map analysis. The main aspects to investigate are map complexity,...

The present work focuses on the manufacturing of Ti-6Al-4V parts using hot single point incremental forming (SPIF), a non-conventional forming technology mainly oriented toward the fabrication of prototypes, spare parts, or very low volume series. In the used procedure, the entire sheet is heated and kept at uniform temperature while the tool incre...

Hybrid stacks made of carbon reinforced plastic (CFRP) and Ti-6Al-4 V alloy (Ti) are often drilled together to reduce positional errors, enhance tight tolerances and minimize machining time. However, this is a complex task due to the dissimilar properties of each material. Tool geometry has a significant impact on the machinability of CFRP/Ti stack...

The present work focuses on a new approach to hot form hard-to-work materials by Single Point Incremental Forming (SPIF) technology using a global heating of the sheet. A set of trials was carried out in order to identify the optimum temperature cycles to minimize geometric distortions associated to each process stage on the fabrication of parts ma...
