Abstract

An important property of the metallic biomaterials used in medical applications is their machinability. A good knowledge of this property is a major advantage in terms of the changes that have been made lately in the medical practice due to the shift to value-based healthcare solutions that have led to increased cost-cutting requirements while keeping the same qualitative requirements for this type of products. Having a good biocompatibility and mechanical properties, the Co-Cr alloys are very often used in medical applications such as dentistry and orthopaedics. When talking about machinability, one of the most important technological parameters in machining process is represented by the cutting forces which are used for determining the necessary machining power and dimensioning the cutting tools. The aim of this research paper is to present the experiments conducted in order to determine a cutting force prediction mathematical model when turning a biocompatible CoCrMo alloy by using TiAlN PVD coated inserts.
