In-Process Measurement of Barkhausen Noise for Detection of Surface Integrity during Grinding

Applied Sciences, 2022
The Barkhausen noise (BN) analysis is a method increasingly used for the post-process assessment of thermo-mechanical surface damages from grinding and has several advantages compared with the established nital etching method.

Mechanically Robust and Depolymerizable Polyesters With Near‐Complete Monomer Recovery for Circular Additive Manufacturing

Advanced Materials, EarlyView.
A sustainable δ‐lactone‐based polymer platform enables multimodal additive manufacturing through DLP, DIW, and FFF, combining tunable crystallinity, photocurable networks, mechanical robustness, and functional response. The printed materials can be mechanically reprocessed and chemically depolymerized into recoverable monomers, demonstrating a closed ...

Study of thresholds to burning in surface grinding process [PDF]

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2005
This work aims at finding out the threshold to burning in surface grinding process. Acoustic emission and electric power signals are acquired from an analog-digital converter and processed through algorithms in order to generate a control signal to inform the operator or interrupt the process in the case of burning occurrence.

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Development of Non-Destructive Technology for Detecting Grinding Burns

International Journal of Automation Technology, 2013
The nitric acid corrosion method that is currently in use in the production field to inspect for grinding burns on workpieces has some disadvantages: its detection levels depend on people and equipment, and is a destructive inspection method that does not allow for a total inspection.

Monitoring of Grinding Burn by Acoustic Emission

, 2012
La combinación de señales de emisión acústica y potencia de corte se ha utilizado con éxito para determinar los parámetros indicativos de combustión (Kwak y Ha, 2004). Estas señales, adecuadamente manipuladas, permiten la implementación de un sistema de control de quemado en tiempo real, optimizando así el proceso de molienda (Dotto et al., 2006). Esto
