Cryogenic turning of titanium alloys: Machinability characteristics and environmental consequences

The physical and mechanical qualities of titanium alloys make them popular in the aircraft industry. Machinability remains the key difficulty in improving productivity and surface quality with these mate-rials. Cryogenic machining has recently become popular as a low-cost and environmentally friendly method of cooling. A strong contender for applications requiring vigorous metal removal, especially from complicate-to-cut materials. When it comes to tool life and surface quality, cryogenic machining and flood machining are compared in this study. Cryogenic and flood turning examination on Ti-6Al-4 V at several cutting conditions were used for this type of analysis. The co-indicator method was used in order to relate environmental effect of every technology in a life cycle analysis. An improvement in environ-mental performance, as well as an increase in tool life and surface quality, was achieved by the use of cryogenic technology in place of flood.Copyright (c) 2022 Elsevier Ltd.
