Study of analysis of cutting tool wear during drilling of a new stainless steels and accompanying phenomena in the cutting zone

摘要

This article presents the results of experiments that concerned the verification of the tool wear and machined surface conditions of workpieces from a new austenitic stainless steel with Extra Low Carbon (ELC) X2Crl6Ni9MoTi and cutting tool wear. The results of cutting zone evaluation under cutting conditions (cutting speed vc=60 m/min, depth of cut ap= 3.0 mm and feedf= 0.05 mm per rev.) are a definition of shear level angle and the texture angle. For X2Crl6Ni9MoTi steel ΦI is 34°. The acquired results are interesting in that for the defined conditions we can achieve a quality outer surface after cutting with roughness parameters down to around 0.65 urn. Very good results were mainly achieved when cutting speed was 60 m/min and the feed was 0.05 mm per rev. for steel X2Crl6Ni9MoTi.
