Change of Material Deformation under the Machined Surface when Drilling Steel C45 and DIN 1.4301

Abstract:

The basic hypothesis of this article focuses on the study changes in deformation under the machined surface of stainless steels and steel C45 when drilling. The problem of drilling holes with diameter D=5 to 12.5 mm resides in the fact that 25 to 30% of these holes do not comply with prescribed requested requirements. This article presents the results of experiments focusing on the study of the damage process in helical drills with diameter d=8.0 mm when drilling into austenitic stainless steel DIN 1.4301 and steel C45. This study also includes an analysis of accompanying phenomena in the cutting zone by measuring some selected parameters.
