Research, activities and impact
Akash Nag explores non-traditional machining techniques such as microabrasive waterjet and electric discharge machining as modern alternatives for precision materials processing. In the case of micro-AWJ, the focus is on harnessing the energy of finely controlled waterjets with high abrasive velocity to enable precise cold and damage-free micromachining. Research with WEDM demonstrates the ability to ultra-precision machine electrically conductive materials using spark erosion, allowing complex geometries and mirror-like surface finishes to be achieved without mechanical stress.
Together, these studies demonstrate how µ-AWJ and WEDM can serve as complementary technologies for advanced manufacturing, particularly in fields such as biomedical engineering where surface integrity, precision and functional performance are critical. Most of the research is conducted in the context of ongoing projects provided by the Czech Republic Grant Agency and European Union projects (REFRESH).
“My goal is to improve the development of precise and energy-efficient material processing techniques that reduce environmental impact while optimizing performance. These technologies offer significant potential, particularly in fields such as biomedical engineering where precision and surface integrity are key. I aim to translate these capabilities into practical applications that will bring significant benefits to industry and healthcare. This includes improving the functionality of medical implants and facilitating the manufacture of complex micro-components while minimising waste. For me, science is not only a pathway to knowledge, but also a means to solve real problems and create value in key areas.”
