An Investigation on Machinability during Turning Hardened Steel in Dry Condition
Abstract Turning of hard materials is usually experienced to have poor machinability. However, to have high productivity, it is desired to go in for turning of hard materials. In the present work, turning of hardened AISI 4340 steel is explored to judge machining performance of plain and groove-type chip breaking TiC coated carbide inserts under dry conditions under different cutting velocity and feed. AISI 4340 steel is considered to be hard and difficult-to-machine. Hence, machinability of this tool inserts and workpiece material combine under different conditions is explored. It is found out that at a cutting velocity of 272 m/min and feed of 0.1 mm/rev, better machinability has been achieved with the wide groove tool insert than that with the other tool inserts used in this work, and hence, may be recommended.
