insert in finish hard turning compared to multilayer TiN and ZrCN coated carbide inserts. Thrust force (Fy) is found to be the larger component of turning forces. Chipping and catastrophic failure of uncoated carbide insert is primarily due to such higher thrust force (950 N) and found unsuitable in hard turning within the parameter investigated. It is also evident that turning forces for ZrCN coated carbide insert are slightly lower than TiN coated carbide insert during machining. This reason may be attributed due to the higher growth of wear during initial period of machining using TiN coated carbide insert.
