Abstract
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 mu m. Furthermore, tool wear performances are observed for each experiment condition.
