AN INVESTIGATION ON EFFECT OF CUTTING PARAMETERS ON MACHINING FORCE AND CHIP MORPHOLOGY IN CNC TURNING OPERATION OF INCONEL 718

Inconel 718 is widely used in space, nuclear and thermal industrial components due to its ability to maintain strength at elevated temperatures. The exploration of the machining parameters of the material can provide a data to the manufacturing engineer to understand the machinability of the Inconel 718. The effect of cutting parameters on machining force can provide required strength from the cutting tool and machine tool to provide stable cutting operation. Also, effect of cutting parameters on chip morphology can provide insight stability of the operation and safety of the operation. This paper presents the results of experimental investigation on the effect of cutting parameters on machining force and chip morphology in CNC Turning Operation of Inconel 718.The results show that the feed is the most significant parameter followed by cutting speed, depth of cut. The results also show that the chips thickness keep on increasing as the cutting speed and depth of cut are increased. The chip formation is mostly affected by the change of cutting speed followed by the depth of cut and the feed rate.
