High productivity micro rotary swaging

open access: yesMATEC Web of Conferences, 2018
Rotary swaging is an incremental forming process with two main process variations plunge and infeed rotary swaging. With plunge rotary swaging, the diameter is reduced within a limited section whereas the infeed rotary swaging enables a diameter ...

Electropolishing and Shaping of Micro-Scale Metallic Features

open access: yesMicromachines, 2022
Electropolishing (EP) is most widely used as a metal finishing process. It is a non-contact electrochemical process that can clean, passivate, deburr, brighten, and improve the biocompatibility of surfaces.

Adaptive laser shock micro-forming for MEMS device applications.

open access: yesOptics Express, 2017
Laser shock micro-forming is a non-thermal laser forming method that uses laser-induced shockwave to modify surface properties and to adjust shapes and geometry of work pieces. The magnitude and spatial distribution of the laser-induced shockwaves depend

Thermo-micro-mechanical simulation of bulk metal forming processes

open access: yes, 2019
The newly proposed microstructural constitutive model for polycrystal viscoplasticity in cold and warm regimes (Motaman and Prahl, 2019), is implemented as a microstructural solver via user-defined material subroutine in a finite element (FE) software ...

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Development of a new machine system for the forming of micro-sheet-products [PDF]

open access: yes, 2008
Most of the developed micro-forming machines were based on standalone concepts which do not support efficient integration to make them fully automated and integrated.
