“a Study of Tool Wear in Turning of Pure Aluminum and Drilling of Cfrp /ti
نویسندگان
چکیده
Tool wear in turning of pure aluminum and drilling of carbon fiber reinforced plastics (CFRP)/titanium (Ti) stacks was investigated due to their importance in modern manufacturing. Although pure aluminum is a ductile metal while CFRP contains brittle carbon fibers, there exist also few important similarities which impact tool wear. For instance, neither work material contains inclusions harder than the tool material. Thus, in both cases, the abrasive wear mechanism, which comes from the hard inclusion abrading the tool surface, cannot explain the tool wear. Thus, selecting a tool material solely based on higher hardness does not always provide a longer tool life. This study presents a new explanation for tool wear with these work materials based on our experiments.
