Abstract

Austenitic stainless steels have a wide field of applications, highlighting the field of biomechanics and in particular, in the manufacture of different prosthetic cutting elements, which require a high surface quality to complete their service assignment, in particular resistance to corrosion and its aseptic characteristics. The objective of the work is to obtain the best surface quality during the finishing machining of AISI 304 steel on a CNC lathe. In carrying out the experiments, the cutting speed (2 levels), and the feed rate (4 levels) were used as independent variables. The depth of cut   remained constant. Titanium nitride coated plates were used as cutting tools. The process was carried out with refrigerant fluid. As a result, the influence of the feed speed and cutting speed on the surface roughness values ​​was determined, obtaining Ra values ​​of 0.198 and 0.204 µm. The experimental results obtained were subjected to a multiple regression analysis, demonstrating that the model is highly significant and fits well to the available data.
