Investigation Into Coal Cutting Operation by Using Conical Pick of Cast Iron with LH710 Coated Tip

In the present paper, analysis of coal cutting has been carried out by conical pick which was developed by cast iron mixed with 21% (by weight) mild steel. The conical tip of pick was coated with material LH710 (hardness 40 RC) which is basically an alloy of Fe, Mn, Cr and Ni. The coal sample was cut linearly by using shaper machine. Parameters as depth of cut, amount of coal removed and temperature generated during cutting were analyzed for different tilt angle of tool and best compromise was found out among them.
