Study of changes the Tool Wear of the Cutting Tool Part of Stainless Steels ELC X04Cr18Ni9Ti during Drilling

摘要

The basic hypothesis of this article focuses on the study changes in the tool wear during drilling of stainless steels ELC X04Cr18Ni9Ti. The problem of drilling holes with diameter D=2 to 8 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=8.0 mm when drilling into austenitic stainless steel ELC X04Cr18Ni9Ti. This study also includes an analysis of accompanying phenomena in the cutting zone by measuring some selected parameters.
