Development and experimental validation of a macroscopic analytical model aiming to generate metal-FRP stacks drilling cutting force and torque

摘要: Composites materials and especially FRP are increasingly employed in many fields of applications (transport, aerospace, …) due to the current trend improving global energy performances new designs notably by mass saving. However use metallic such as aluminum titanium alloys is still necessary cases a lot structures made dual technology called stacks (panels composed different layers metal bounded together). Combining properties these offers advantages regarding mechanical structural aspects. This nevertheless for same reason that machining drilling laborious task: tools cutting conditions way too divergent avoid vibrations, problems dimensional tolerances delamination composite. The knowledge characterization forces first step solve issues. purpose this article provide an accurate macroscopic analytical model fitted compare it quantitatively with experimental tests. given divided two parts (i.e. respectively adapted materials) based on discretization edge. proposed algorithm able predict accurately force torque along time function conditions, tool material configurations. A reverse least squared method used obtain empirical input parameters, allowing minimize number tests parameters.
