Tool wear analysis of cutting Ti-5553 with uncoated carbide tool under liquid nitrogen cooling condition using tool wear maps

Abstract

Tool wear experiments involving Ti-5553, a newly developed titanium superalloy, were carried through cryogenic machining with liquid nitrogen. Tool wear modes under various cutting parameters were observed and recorded, and the tool wear mechanism was analyzed. The tool wear map for the rake face was constructed to analyze tool wear qualitatively. Using the experimental results, the tool wear map for the flank face was developed to analyze tool wear quantitatively using the three-dimensional isosurface and response surface methodologies. This new method of combining the tool wear maps of the rake and flank faces provides a quick and useful reference for selecting suitable cutting parameters.
