The Effect of TiAlN coated Ball End Mill and MQL Cutting Condition on Cutting characteristic of High Hardness Steels
고경도 강재의 MQL 가공시 초경 볼 엔드밀의 TiAlN 코팅 조건이 절삭 특성에 미치는 영향
Abstract
This paper is studied on the effect of TiAlN coated Ball End Mill and MQL(Minimum Quantity Lubrication) cutting condition on cutting characteristic of high hardness steels. KP4 steels[HRC32] and STD11[HRC60] heat treated steels were used as the workpiece and WC-Co ball end mill and single and multi layer TiAlN coated ball end mill were utilized in the cutting tests. MQL device was used to spray botanical oil coolant. Result showed that TiAlN coated ball end mill were increased the cutting length than WC-Co ball end mill in the cutting speed[
