The Development of Micro-Cutting Technology and Micro-Machines Abstract: Micro-machining technologies are set to become an indispensable key technological force in the future; among these, cutting technology, as the most fundamental processing step, requires continuous study and mastery. At the same time, micro-machines have emerged in response to this need.

Flame cutting uses oxygen as the auxiliary gas; it enhances efficiency through the energy released by the oxidation of the metal, making it suitable for processing thick steel plates; fusion cutting utilises inert gases such as nitrogen, resulting in smooth, oxidation-free cut edges.
