【Abstract】 A mathematical model for numerical emulation of cutting forces in drilling using drills with indexable inserts based on oblique cutting theory combined with experimental approach is developed. With the help of this model, the influence of the spacial location of the inserts on the drill body upon the cutting forces and torque can be studied. As a result, the optimized inserts location parameters, which will generate minimum radial cutting forces, can be determined for a given cutting condition.更多还原
