Toward sustainable manufacturing: A triple-bottom-line review of dry machining of titanium alloys

Titanium alloys are vital in aerospace, biomedical, and energy sectors due to their high strength and corrosion resistance. However, their poor machinability and the environmental impacts of conventional coolants necessitate sustainable alternatives. This review critically evaluates the dry machining of titanium alloys...
