Changing Deformation under the Machined Surface in the Cutting Zone for the Different Materials during Drilling

Abstract:

The basic hypothesis of this article focuses on the changes in the plastic deformation under the machined surface during drilling. For experiments applied a new Cast Iron GTW 35-04, Stainless steels DIN 1.4301 and ISO C45 carbon steel. The problem of drilling holes with diameter D=2 to 15 mm resides in the fact that 20 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=6.0 mm. This study also includes an analysis of accompanying phenomena in the cutting zone by measuring some selected parameters.
