Effect of cutting parameters on tool wear when trochoidal pocket milling Ti6Al4V

Despite being an attractive material for aerospace components such as engine parts and airframes, titanium alloy is categorized as a difficult-to-machine material which results in rapid tool wear and tool failure. It was reported that trochoidal machining method is preferred as compared to conve...
