"Cryogenic machining technology" is a method used to produce high-performance parts in industries such as aerospace and aviation in an eco-friendly manner. It involves spraying cryogenic substances like liquid nitrogen onto cutting tools to cool them, followed by manufacturing and processing parts.

At this time, the cutting tools cooled to cryogenic temperatures exhibit high strength, extending the tool's lifespan and demonstrating excellent wear resistance. This leads to significant efficiency gains in parts production, and since environmentally harmless substances like liquid nitrogen are used, it is recognized as an eco-friendly machining technology.

The "numerical analysis model" developed by Professor Kim's research team is a process prediction system that mathematically analyzes the effects of low-temperature substances on cutting tools and workpiece materials in terms of machining load and material temperature. The research was supported by the National Research Foundation of Korea.

Professor Kim stated, "Cryogenic machining is an eco-friendly technology applicable to various industries and simultaneously a technology that can improve process efficiency. Understanding and utilizing cryogenic machining technology is expected to help enhance the competitiveness of parts production in industries such as aerospace, space, and nuclear power."

Meanwhile, the research was published in the SCI-level international journal, International Journal of Advanced Manufacturing Technology.
