Abstract


The process of reaming stainless steel (X5CrNi18-10) is difficult due the mechanical and chemical properties of the material. A small number of scientific papers address the subject of reaming in stainless steel. The main purpose of the experiments presented in this article is to foreground the influence of the cutting edges roundness to increase the finishing tools durability. This paper also studies the wear behavior of reamers during the machining process and the holes roughness evolution. The article contains details about the microgeometry and wear of the reamer and the holes surface quality.
