Abstract

This paper is about the tribology factor regarding the chip formation in machining hardened carbon steels using coated carbide tool. The machining parameters considered for the investigation are cutting speed, feed rate, and depth of cut under dry cutting condition using coated carbide tools. The chip shape formed is due to the combined effect of machining parameters. The favorable type of chip which gives good surface finish is formed when the depth of cut is high. The small value of coefficient of friction shows that the shear angle is larger which results in smaller shear plane angle that gives lower value of cutting force needed to remove the chips and lower cutting temperature results during the machining process The interaction effects of the variables have been considered to draw the graph. Three levels of the feed, speed, and the depth of cut is used to generate readings.
