Investigation on Machinability in Finish Turning of AISI 52100 Steel Using Different Tool Inserts in Dry Machining

This paper concerns with machinability studies in finish turning of AISI 52100 steel using various tool inserts. This steel is applied in different structural and other industrial applications. Turning tests are performed under different cutting velocity and feed with plain, narrow groove and wide groove coated carbide tool inserts. Using these diverse conditions, types of chips formed, cutting force, etc., were noted, and machinability of the tool-work combine under different conditions is explored, so that some conditions can be found out at which good machinability can be achieved. Although narrow or wide groove chip breakers are used, chip breaking is not much observed in general. Fair machinability is observed while turning using all the three types of inserts. However, fairly good tool performance is obtained when plain carbide insert is employed at higher cutting velocities of 174 and 274 m/min at the chosen feed even in dry condition.
