In this study, optimization of process parameters of drilling operation in an horizontal machining center with C35 Mod BY workpiece material with TiCN coated indexable drilling inserts has been targeted. Surface roughness, perpendicularity and cylindiricity were selected as performance characteristics. Controlled factors were selected as hole diameter, hole depth, feed-rate and peripheral cutting speed. A L9 (34) orthogonal array has been employed and experimental runs have been planned. The performance characteristics were measured and various signal to noise ratios were calculated. Analysis of Variance has been carried out and effect levels of the controlled factors has been analyzed. From the analyzed data confirmation experiments have been carried out and the results were analyzed.
