SURFACE MICROHARDENING STUDIES ON STEELS AFTER HIGH FEED MILLING

Abstract

The paper deals with the impact of high-speed machining production methods on the integrity of component surfaces. One has to point out that cutting conditions during machining have a significant impact on the final properties of surface and subsurface layers of the workpiece. The conclusion summarizes and analyzes achieved results of experimental activities on stainless austenitic steel 1.4301, hardened tool steel 1.2343 and high-speed steel 1. 3344 (ASP 2023). The results of the work experimental parts demonstrate influence of cutting parameters on selected surface integrity ones, specificallystrengthening of surface and subsurface layers. The performed experiments show that microhardness of a surface layer of machined material can be influenced by suitable cutting conditions and other cutting process parameters.
