概要: This paper deals with the machinability of BN added Steels in end milling. The cutting tests were carried out by end mil … ling carbon steel JIS S45C, S55C and these BN added steels with carbide tool and TiAlN coated carbide tool. Tool wear, cutting temperature, and, surface roughness were measured and discussed. In end milling BN added steel with square end mill, the progress rate of flank wear width was decreased and fracture at corner was suppressed in comparison with that in machining standard steel. In case of ball end mill, flank wear in end milling BN added steels were smaller in comparison with standard steel. In case of S45C, boundary wear was observed, however it was not observed in end milling BN added steel. BN added showed almost the same surface roughness as standard steel. The temperature of flank wear part in turning work based S55C were 50 °C higher in comparison with S45C base work. The temperature of throw away end mill was higher 100°C in comparison with solid square end mill. There were not significant difference between the temperature in end milling standard steel and BN added steels. 続きを見る

概要: This paper deals with the machinability of BN Added Steels in turning with several cutting tools. The highest Al content TiAlN coated carbide tool showed smaller flank wear and crater depth than those of the other TiAlN, TiC, TiN and … TiCN coated carbide tools. It shows that these tool wears depend on the affinity between tool surface and adhered layer including AlN. The wear of the alumina ceramic tool in turning BN added steel was smaller than that in turning standard steel. However the wears in turning low Al content BN added steel and high Al content carbon steel were almost the same as that in turning standard steel. It shows that appropriate Al and BN in work material are necessary to obtain the longer tool life. The wears of the TiC added alumina ceramic tool and the CBN tool in turning BN added steel were also smaller than those in turning standard steel. 続きを見る
