Effects of microstructure of 38XH3MΦA steel on abrasion wear of instrument

Abstract

This paper concerns with effects of various types of microstructure on machinability of 38XH3MΦA steel. The machinability of steel is preliminarily evaluated by measuring the abrasion wear of end mill cutters upon machining samples of different microstructures in the same cutting condition. The obtained results can be the base for choos- ing optimal microstructure to machine this type of steel.
