With the invention of new technologies and development of the new materials, wide ranges of materials are made
available for their usage in medical applications. These materials are referred as biomaterials, among which the metallic
biomaterials have become an intensive source of interest for the researchers, doctors and surgeons owing to its costs and
highly impressive properties. The metallic biomaterials play a predominant role in dental and orthopedic fields as a structural
biomaterial in surgeries. Among all the metallic biomaterials Co-based alloys, Ni-based alloys and Ti-based alloys are gaining
more popularity owing to their high mechanical strength and fracture toughness. However, utilizing these materials require
high degree of machining. In the current study, an effort has been made towards improving the machinability of Ni-based alloy
without making use of any coolant or lubricant during the machining operation keeping in mind the aspect of sustainability.
The machinability of the alloy is improved by altering the cutting tool properties and conditions by making use of the
mechanical treatment technique i.e. micro abrasive blasting. The process improves the cutting tool performance by altering its
surface and sub-surface properties thereby improving the characteristics of machined surface. Dry machining of these metallic
biomaterials with the use of altered tools is not only an effort towards sustainability but also helps in reducing any type of
reactive action between the two.
