The paper investigates the machinability characteristics of the CoCrMo alloy ASTM F1537, usually utilized for the production of joint replacements and fixation devices thanks to its high strength, good wear and corrosion resistance, and excellent biocompatibility. This research work intends to overcome the lack of literature data about this alloy machinability, even if its use in the biomedical sector is intensive and it is usually subjected to various machining operations for the implants production. Turning tests were carried out under lubricated conditions at different cutting speeds and feed rates typical of finishing cutting operations. The alloy machinability was analysed in terms of tool wear and cut surface integrity as a function of the cutting parameters.

Abstract
The paper investigates the machinability characteristics of the CoCrMo alloy ASTM F1537, usually utilized for the production of joint replacements and fixation devices thanks to its high strength, good wear and corrosion resistance, and excellent biocompatibility. This research work intends to overcome the lack of literature data about this alloy machinability, even if its use in the biomedical sector is intensive and it is usually subjected to various machining operations for the implants production. Turning tests were carried out under lubricated conditions at different cutting speeds and feed rates typical of finishing cutting operations. The alloy machinability was analysed in terms of tool wear and cut surface integrity as a function of the cutting parameters.Pubblicazioni consigliate
