Studium obrabialności stali nierdzewnej X2Cr18Ni8 poddanej wierceniu

STRESZCZENIE: Przed wdrożeniem nowych tworzyw konstrukcyjnych do procesu obróbki skrawaniem niezbędne są precyzyjne i niezawodne informacje o ich obrabialności, przy czym powinny być one sprawdzone aktualnymi metodami. W artykule przedstawiono wnioski z badania obrabialności austenitycznej stali nierdzewnej X2Cr18Ni8, opisano także właściwe parametry strefy skrawania w procesie wiercenia. W artykule skupiono się na analizie czterech podstawowych parametrów obrabialności stali w wybranych zakresach.

SŁOWA KLUCZOWE: wiercenie, strefa skrawania, odkształcenie plastyczne, stal nierdzewna, obrabialność.

ABSTRACT: Precise and reliable information on the machinability of a material before it enters the machining process is a necessity, and hypotheses must be tested through verification of actual methods. This article presents conclusions of machinability tests on austenitic stainless steels X2Cr18ni8 and describes appropriate parameters for the cutting zone during the process of drilling. The article focuses on the analysis of selected domains through four basic some parameters of steel machinability.

KEYWORDS: drilling, cutting zone, plastic deformation, stainless steels, machinability, machined surface.
