Abstract

This article presents the results of experiments that concerned the verification of machined surface conditions of workpieces from a new austenitic stainless steel with Extra Low Carbon (ELC) Cr22Ni9MoTi compared with stainless steels Cr18Ni8. The results of cutting zone evaluation under cutting speed 80 m/min, depth of cut 2,75 mm and feed 0,08 mm per rev., a definition of shear level angle Φ1. For Cr22Ni9MoTi steel Φ1 is 36° to 39°. 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 μm at cutting speed 80 m/min and feed 0.08 mm per rev.
