Experimental Investigation on the Machinability of Iron Based Superalloys
In this study, drilling experiments of Incoloy A-286, which is a iron based superalloy, have been carried out. Three different feed rates, three different cutting speeds, two different point angle and three different tool coatings were chosen. Optimum cutting conditions were determined in order to obtain minimum drilling forces and torque. The effects of cutting speed, feed rate, tool material on the thrust force were obtained. Experimental findings indicated that generally, cutting forces increased with a higher feed rates but decreased with a lower point angles.
