Study on Cutting Force and ToolWear while Milling Ni3Al-Based Superalloy
Ni3Al-basedsuperalloy is a kind of typical hard-to-cut material due to its low thermal conductivity and high strength at elevated temperatures, which lead to dramaticaltool wear in the milling progress.To understand the cutting force and the tool wear behavior in milling process, the influence of cutting parameters on cutting forces and tool wear in the milling of Ni3Al-based superalloy by using carbide coated milling cutter is investigated in this paper.Through orthogonal experiment, a linear regression is carried out with the results and an empirical formula for milling forces applicable to the test condition is derived.The results show that the cutting forces increase with the increase of cutting feed rate, radial depth and axial depth of cut.Besides, thefeed per tooth is the main factor affecting of cutting force,andaxialdepth of cut has greatest influence on tool wear.The proposed research provides the basic data for evaluating the machinability of milling Ni3Al-based superalloyand the recommendedcutting parameters can be applied in practical production.
