Experimental examination of tool wear during turning of Ti-grade 2 alloy in dry and minimum quantity lubrication (MQL)

Abstract

In any manufacturing industry cost and productivity are the major concerns to be taken care. There are several factors which can be used to control these factors and while it comes to machining tool wear plays a major role in deciding the productivity and cost of the machining process. Recently many studies have been done on the different alloys of titanium and it is found to be very useful and difficult to machine material as well. In this work turning of one of the titanium alloys is used to study the tool wear behavior during dry and minimum quantity lubrication (MQL) machining conditions. In the current work tungsten carbide (WC) insert is used for machining process. After the machining Taguchi’s analysis is used to analyze the results obtained after the machining. In this work spindle speed, feed, and depth of cut are taken as the input parameters along with the machining condition. From the results it is found that MQL provides the better results to minimize the tool wear.
