Machinability

Machinability is a relative measure of how easily a material can be cut with a sharp tool while providing a high-quality surface finish and long tool life. It is influenced by the material's hardness, tensile strength, and thermal conductivity. In steel manufacturing, elements like sulfur or lead are sometimes added to improve machinability by acting as internal lubricants and breaking up "chips." For a researcher, a high machinability index means lower energy consumption and faster production cycles during the final fabrication of components.
