A Comparison of Machinability in Hard Turning of EN-24 Alloy Steel Under Mist Cooled and Dry Cutting Environments with a Coated Cermet Tool

In this current research, mist cooling and dry cutting effects on cutting force, flank wear, chip morphology, crater wear, surface roughness and microhardness of chip have been evaluated during hard turning operation of EN-24 grade steel having hardness of 48 HRC. Water-soluble oil was applied for c...

Description
Summary:In this current research, mist cooling and dry cutting effects on cutting force, flank wear, chip morphology, crater wear, surface roughness and microhardness of chip have been evaluated during hard turning operation of EN-24 grade steel having hardness of 48 HRC. Water-soluble oil was applied for cooling and lubricating purposes in mist cooling, and a comprehensive comparative analysis was performed with dry machining environment. Dry machining was found more effective as compared to mist cooling technique against the chip microhardness and cutting force. For other responses like crater wear, flank wear, surface roughness and chip morphology, the cooling setup having coolant delivered in mist form performed better than dry machining owing to reduction in cutting zone temperature and complimentary modification in chip–tool interaction during hard turning.
