Abstract: The major needs of machining are high material removal rate, good work surface finish and low tool wear. Industries are hiring to increase economical benefits by reducing the cost of production. These objectives can be achieved by using proper cutting tool material and cutting parameters. This report presents comparisons of two different coated carbide inserts under different cutting parameters used during machining of cylinder liners made up of grey cast iron. The comparison has been realized through the tool life tests and productivity. The measurement has been carried out from rough boring operation at three cutting speed (Vc) and feed rate (f). Depth of cut (doc) is kept constant at 1.5mm. Cutting tool used in this work is titanium nitride (TiN) coated carbide and comparing with Multilayer coated tool is titanium nitride (TiN) + titanium carbo nitride (TiCN) + Aluminium oxide (Al2O3) coated carbide inserts. The type of the insert is SNMG 120408. Cutting conditions used is speed (Vc) 100m/min, 125m/min, 150m/min. Feed rate (f) 0.25mm/rev,0.3mm/rev,0.35mm/rev. Finally results of the present work determine the appropriate parameter for increasing the tool life, and productivity.
