압축냉각공기를 이용한 공구수명 향상에 관한 연구
The study on improving tool life using compressed chilly air
초록
High-speed machining generates concentrated Thermal/fractional damage at the cutting edge and rapidly decreases the tool life. This paper is aimed at improving the tool life using compressed chilly air. In this paper, the experiments were carried out in various cutting environments, such as dry, wet and compressed chilly air. Tool life were measured to evaluate machinability in high-speed milling of various materials. With respect to the cutting environment, compressed chilly air increased tool life. However, the wet condition decreased tool life due to the thermal shock caused by excessive cooling.
