Surface quality and dimensional precision significantly affect to strength and performance of working machine parts that are contacted one another. Additionally, cutting tool geometry and cutting parameters are the most important factor affecting to cutting force, surface roughness and productivity in machining. In this paper, optimization of cutting parameters and tool nose radius (variables) was performed for which F-c and R-a are occurred in machining of AISI 316L austenitic stainless steel. For this purpose, the machinability experiments were carried out using Taguchi's L-9 orthogonal array. An analysis of variance (ANOVA) was employed to determine the level of contribution and effects of variables on Fc and Ra values measured during the machining experiments. Optimal values of variables which were obtained using the S/N ratios were found at different levels for F-c and R-a. According to the ANOVA results, the most significant variable affecting to cutting force and surface roughness values was determined as feed rate.
