Research on the Cutting of High Nitrogen Austenitic Stainless Steel

Abstract:

The high nitrogen austenitic stainless steel is a kind of difficult-to-machine material. On the basis of material properties analysis, and through comparison test of tool wear resistance, this article made a study on the typical wear & breakage patterns and wears mechanism of insert during the cutting process, and made an analysis on the affection of the mechanical properties of tool materials of various brands to the cutting technological parameters. The results show that the tool wear and breakage are mainly expressed as adhesive wear of rake face and micro chipping of end cutting edge. Compared with the other inserts, YG8 has the best property and a longest life span within the 50~75 m /min cutting speed range.
