Optimization of Surface Roughness Performance in The Turning of AISI 4140 Steel With Multi Directional Cutting Tool

15863

Presented study discusses the turning of AISI 4140 steel with groove cutting tool at the rough machining conditions (high feed rate and depth of cut). Experiments based on Taguchi’s L8 orthogonal array at the different levels of cutting speed, chip breaker type and nose radius conducted. As a result of the analyses carried out at the confidence level of 95%, nose radius has the most significant effect on the roughness followed by chip breaker type and chip breaker type–nose radius interaction, and optimum roughness is obtained as 0,572 μm. Furthermore, tool wear performances are observed for each experiment condition.
