  • Archive ouverte HALAn approach to modeling the chip

    The determination of the chip thickness in 5-axis ball end milling is most fundamental to calculate the cutting force which affects the machining stability and surface quality. In the 5-axis ball end milling adding to the parameters of the 3-axis milling we have two important parameters which are the tilt and the lead angles. They affect the engagement region and the chip thickness and modify

    At last a hybrid milling model allowing the calculation of the 3D cutting forces is presented. The interest of the suggested approach is to be freed from classically needed machining tests Those are replaced by 2D numerical tests using the SPH model. The developed approach proved its ability to model the 3D cutting forces in ball end milling.
