Development of Cutting Forces and Surface Roughness Prediction Models for Turning a CoCrWNi Alloy

Abstract:

This paper presents a research conducted in order to identify the cutting parameters effect on turning cutting forces and on the resulted machined surface quality for a CoCrWNi alloy. This alloy is a biomaterial used in medical applications for implants manufacturing. The main objective of the research is the development of prediction models for the turning cutting forces and the Ra roughness parameter for dry longitudinal turning with TiAlN PVD coated inserts. In order to achieve this objective, thirteen processing experiments were carried out, during which the cutting forces and roughness parameters were registered. The research results consist of the prediction models for cutting forces and Ra roughness parameter.
