Abstract Application of aluminium alloys has increased for light-weighting the sheet metal parts in manufacturing of automobiles. Formability is important in sheet metal forming of aluminium alloys. In the assessment of formability of sheet metals, stretch flangeability or edge formability is an important aspect in application such as flanges or plunged rims. The stretch flangeability refers to the ability to avoid cracking during hole expansion and it is evaluated by performing the hole expansion test. Besides material properties, hole making process also influences the stretch flangeability

The great differences of technologies and systems of each steel mill and the multiple restrictions, methods, and techniques, within a wide dynamic strongly concatenated, do not generalize automation systems feasibly.

Abstract:

A drill bit integrated with a retractable deburring cutter can be used for drilling and deburring exit burrs in a single process. In preliminary works, the authors learned that the retractable cutter may cause hole widening during its passage through the holes. A new design for the deburring cutter is proposed to avoid hole widening. With the new design, mild exit burrs (types I and II) are successfully removed. For large exit burrs (type III), however, the deburring is likely to be incomplete.

Abstract:

Abrasive Waterjet (AWJ) machining is considered an excellent alternative to conventional machining processes due to its superb machining characteristics. More specifically, Abrasive Waterjet drilling is nowadays a promising non-conventional process for obtaining high quality holes. In the present study, drilling experiments based on Taguchi L9 orthogonal design method were conducted via AWJ on carbon fiber reinforced polymer (CFRP) plate at various waterjet parameters, namely, different pressure, abrasive mass flow rate and standoff distance values. The purpose of the experiments was to invest

In response to fragmented approaches in green manufacturing research, this study proposes an integrated decision-support framework that unifies production process diagnosis, multi-resource optimization, and data-driven analytics to enhance sustainability in complex manufacturing systems. Combining theoretical modeling (e.g., dynamic resource-element networks), empirical case studies (12 cross-industry cases in automotive, electronics, and textiles), and systematic diagnostics, the research addresses inefficiencies in traditional ERP-MES-PCS architectures, where manual decision-making and disco

Abstract:

By filament winding technology, a pin hole can be formed in the process of composite manufacturing through wrapped fiber tow around pin, so fiber tows around the pin hole are continued. The paper presents the failure analysis for this kind of pin hole. The experimental results and numerical results show that the pin hole has a good tensile bearing ability. According to Hashin criteria, numerical results show that main failure modes are fiber tensile failure and matrix tensile failure which are agreed with the experimental results.

Abstract:

The monitoring of surface finishing processes in aerospace manufacturing industry becomes one of key issues to maintain the overall quality of product or part. To date, the surface quality monitoring post machining processes such as deburring, use visual inspection, surface roughness test or laser gap gun. The whole manufacturing process then requires a considerable amount of time as the production line must be halted due to these measurements taking place. This study presents an online monitoring system to measure the chamfer quality of replica boss hole post-deburring process. Vibration sign

The COVID-19 pandemic has caused millions of deaths and devastated communities across the globe. Vaccines will play a key role in bringing the pandemic under control, with successful clinical trials, authorizations and roll-out having now occurred in several countries. However, large-scale manufacturing of such vaccines remains a bottleneck to delivering doses to billions of people at risk of infection, as well as producing new versions of the vaccines that target variants. Here we discuss the current status of manufacturing, focusing on the adenovirus-vectored vaccine developed by the Univers
