Carbon Fiber Composite Materials Finite Element Simulation Analysis of Cutting Force

Carbon fiber composite material as an advanced composite material is widely used in aviation, aerospace, defense and automotive, electronic information and high-speed machinery and other civilian areas. Since the carbon fiber composite material having a large strength, anisotropy, and poor thermal conductivity and other characteristics. Especially interlayer low intensity, under the action of cutting force when cutting prone to delamination, tearing and other defects, especially in the process of drilling, processing quality is difficult to guarantee. For this stage of carbon fiber composite material machining problems, in this paper, based on the mechanical properties and the finite element technology of the cutting process, to establish the carbon fiber composite material drilling finite element model, and application Deform-3D finite element simulation software to simulate the drilling process of the carbon fiber composite material, to simulate and analysis drilling force and torque for drilling process and verify the simulation results through experiments. More research has important significance to reduce surface defects and tool development and design of the carbon fiber composite material processing.
