...Ye Qi; Vinh Nguyen; Shreyes Melkote; Michael Varenberg This paper presents a study of the wear of high-speed steel cutting tools modified mechanochemically by shot peening their rake faces with a mixture of Al 2 O 3 and Cu 2 S particles. This treatment has been recently proved to reduce cutting...
