Comparison of Round Insert's Lifetime when Milling Inconel 718

Abstract:

This article focuses on the analysis of tool wear mechanisms in milling of Inconel 718. Inconel 718 is tough and highly temperature resistive material, which is used due to its excellent properties especially in aggressive corrosive medium. Machining of this alloy is still complicated. The feasibility of four inserts tested for milling of Inconel 718 has been shown in the work. Different cutting speeds and feeds were used. Experimental tests were performed in order to analyze wear patterns evolution. It was found influence of cutting conditions and type if insert in tool wear mode.
