| Abstract: | Through the cutting experiments, the mechanisms of tool failure when turning Stellite alloy, a difficult-to-machining material, with two kinds of carbide cutting tools, YG610 and YS8, were investigated. Results show that YG610 has better toughness and hardness than that of YS8, and its tool failure mode is represented as the tool wear. YS8 has high hardness and insufficient toughness, and its tool failure mode is mostly the tool breaking. |
