Multi directional turning tools can perform various operations such as cutting, grooving and profile turning with high performance on their own. Tool change and setting times are reduced considerably with the use of these tools. This study discusses surface roughness and wear behavior for different cutting speeds, chip breaker types and nose radii in the rough turning of AISI 4140 steel with physical vapor deposition coated cemented carbide multi directional turning tool. Experimental results based on Taguchi's L8 orthogonal array are assessed through the analysis of variance, main effects and interaction plots. As a result, optimum roughness and an roughness increase percentage are obtained at 0.803 mu m and 19.92 %, respectively.
