Machining of EN-31 Steel and Experimental Analysis of Various Process Parameters Using Minimum Quantity Lubrication

Abstract

The paper presents an experimental study of surface roughness and tool wear in turning operation of EN-31 alloy steel with ceramic tool under different cutting parameters. The investigation shows impacts of three distinctive cutting parameters in particular cutting velocity, feed rate, and depth of cut influencing surface roughness just as tool wear amid turning task of EN-31 alloy steel. The exploratory setup comprises of three diverse cutting rate, feed rate, and depth of cut for turning of EN-31. EN-31 is chosen as the work material in view of its more application. EN-31 has been utilized for ball and roller bearing, turning instruments, beading rolls, punches, and dies, and by its character, it has high opposition nature against wear and can be utilized for parts abstract to serious abrasion wear or high surface loading. From exploratory investigation, it is seen that turning of hardened steel with minimum quantity lubrication (MQL) gives better surface roughness and tool wear when contrasted turning without MQL. The outcomes demostrated that when MQL is connected in machining procedures can diminish the cutting temperature and gives lubrication between tool and workpiece. These lead to longer tool life and enhanced surface quality.
