Abstract

In the present-day manufacturing industry, achieving machining accuracy, high production rate, high material removal rate and increasing tool cutting life is becoming more vital and a particularly difficult task. Machining of hard material imposes a lot of challenges, mainly high temperature generation between tool-workpiece interface. Enormous heat generation adversely affects surface roughness, tool life, dimensional quality of the workpiece and deteriorates the tool life significantly. The use of proper lubrication in machining processes is critically important to modify the conditions of contact area by effective control over frictional interaction which should ensure change in tool-chip interface and machining mechanics. In the present work an experimental investigation was carried out on various MQSL parameters on surface roughness and tool temperature in turning EN 31 steel and the results are compared with dry turning. In order to apply lubricants at shearing interface (chip flow at the rake face of the tool) high velocity MQSL set-up is fabricated. The present work has achieved significant results and helped in concluding the influence of lubricant parameters of MQSL in turning process. © Published under licence by IOP Publishing Ltd.
