Paper Title:
Effects of Tool Geometry and Workpiece Hardness on Surface Roughness in Finish Hard Turning of AISI 440C
  Abstract

In this study, the effects of cutting tool geometry and workpiece hardness on surface roughness in finish hard turning of AISI 440C steel were experimental investigated. Four-factor (hardness, tool geometry, feed rate and cutting speed) two-level fractional experiments were conducted and analysis of variance (ANOVA) was performed. This study showed that the effects of workpiece hardness and tool geometry on surface roughness are statistically significant. Especially lower workpiece surface hardness and larger tool nose angle resulted in lower surface roughness because that the surface hardness influences the workpiece’s flow stress and the tool nose angle changes the contact area between the cutting tool and workpiece.
