INFLUENCE OF THE FEED VARIATION ON TOOL WEAR WHEN MACHINING INCONEL-600

Experimental results of the turning of Inconel 600 show that it is pos sible to change the tool wear mechanism and to increase tool life subs tantially by a proper variation of the cutting feed rate throughout th e cutting process. Experiments clearly demonstrate this phenomenon and show a decrease of approximately 33% of the tool wear. Comparison bet ween constant and variable feed processes are based on constant volume of material removed in a given time span, therefore maintaining a con stant process efficiency for both cases. The results presented in this paper are based on a limited number of experiments and are therefore preliminary in nature.
