An Experimental Study on Machinability of Micro Alloyed Steel with K20 Single Layer (TiN) Coated Carbide Insert

Abstract:

This paper presents the experimental study on machinability of micro alloyed steel. Raw material of chemical composition 38MnSiVS5 of diameter 60 mm and length 250 mm was machined using the medium duty lathe of 2 kW spindle power using K20 PVD single coated (TiN) Carbide insert. The investigation (turning) is carried out with three levels of cutting speed, feed rate and depth of cuts. An average surface roughness(Ra) of machined component and power consumption by the main spindle are measured. The optimum machining parameters have been identified. Results show higher cutting speed influence the good surface finish on this steel. In particular, surface finish is directly proportionate to the cutting speed.
