CBN 볼 엔드밀의 절삭 및 마모특성에 관한 연구
A Study on the Cutting Pertormance and Wear Characteristics of CBN Ball End-Mill
초록
This paper presents the experimental results on the cutting performance and wear characteristics of CBN ball end-mill. The influence of cutting fluids and rake angles on the tool performance is reported. It i found that the neat cutting oil is beneficial to obtain good surface roughness and 30 .deg. of rake angle gives the minimum tool wear. The microscopic investigations reveal that the coated carbide endmills wear by fracture whereas the CBN endimills wear by attritious mode.
