Experimental study on adhesive wear of milling insert with complex groove

Abstract

This paper presents an experimental study on the adhesive wear of a milling insert with complex groove when milling 3Cr-1Mo-1/4V and 0Cr18Ni9 steels. Experimental measurements of milling temperature and milling force were performed. Then the adhesive behaviors and mechanisms between the steels and uncoated carbide were analyzed and discussed. It is found that the high temperature gradient, thermal stress, alternate compressive stress, and tensile stress in cut-in and cut-out, provide a situation for adhesion. Some suggestions for avoiding adhesive wear and the mechanism of adhesive wear of the insert are presented.
